You replaced the broken LCD screen in your laptop with a new screen but it’s not working. Does this sound like your problem? Let’s find out what could be wrong and how you can fix it.
First of all, I assume that your new LCD screen is compatible with the old one. Different screens require different video cables. Make sure you new screen is compatible with your laptop.
OK, let’s say you accidentally damaged the LCD screen in your laptop. A part of the screen still works fine but you cannot use it like that so you decided to replace the screen yourself. You can find LCD replacement instructions in service manuals or this DIY site.
You did some research and purchased a compatible screen, installed it into the laptop, turned it on and… The new screen is not working!!! What could be wrong?
Before you start to panic, check all cable connections again. Check connection between the video cable, LCD screen and inverter board. Reconnect cables just in case.
Take a closer look at the connection between the video cable and LCD screen. It’s possible you accidentally pulled the video cable from the connector during the screen installation.
The video cable has to be seated properly, all the way down.
Also, on some older LCD screens there are very thin pins inside the connector. Take a look inside the connector, make sure there are no damaged (bent) pins.
You can straighten bent pins with a very small screwdriver but this procedure requires a lot of patience and concentration.
Fortunately, most newer LCDs have a different type of connector, without fragile pins inside.
OK, you have reseated all connectors and cannot see anything wrong but the new screen still is not working. What’s next?
Remove the new screen and connect the old one. If the old one works properly (except the damaged area) but the new one is dead, apparently the new screen is defective and has to be replaced. Hopefully it has warranty.
Here’s another scenario. The new screen kinda works. You can see a very faint image but there is no backlight.
If that’s the case, disconnect the new screen from the inverter board and plug in the old screen instead, as it shown on the picture below. If the backlight inside the old screen lights up, apparently the new screen has defective backlight lamp and has to be replaced.

I’m absolutely at my wits’ end here. I have a newly released laptop with a messed up screen, and I can’t find any websites selling the screen part # or model # at all. The official vendor’s website lists the screen, but as out-of-stock, and at either $600+ or $900+. Obviously, I can’t replace my laptop screen with the exact model it came equipped with. So my question is: How do I find out which screens are compatible with my laptop? What are the main sources of incompatibility? I know that my screen was TFT Active Matrix with LED backlight, so I can’t order any with the CCFL backlight. But apart from the size + backlight, is there any way to find out for sure if a certain video cable is compatible with my laptop?
I’ve googled everywhere and this blog seems to be the most helpful and knowledgeable, so I’m really hoping to get some glimmer of hope that I won’t have to put up with a broken screen for the rest of my laptop’s lifetime because I can’t afford a replacement screen. =\
September 24th, 2008 at 6:06 pm
just purchased replacement laptop screen for Dell B120 but replacement lights up but doens’t work, double checked to make sure connections are good, they are. I put the old screen in and can see parts of my desk top. Tried the old inverter with the new screen. Is this a case of a defective screen?
September 24th, 2008 at 10:31 pm
I have old Toshiba laptop tecra a20, first hinges broke down and now I can’t see good on the moniter. how i can solve to change the monitor and the hinges or only the hinges
September 24th, 2008 at 10:31 pm
Valerie,
So they already sell laptops with LED backlight? I’ve never seen or repaired one yet. I guess you can search for the LCD part number on the back side of the screen and then google it.
September 24th, 2008 at 10:41 pm
Remon,
First of all, make sure the new LCD screen is compatible with the old video cable. If you purchased the same screen (same model), apparently it’s a defective one.
September 24th, 2008 at 10:51 pm
duale,
You’ll have to find out why your LCD is not working properly. Take a closer look at the video cable. Maybe the broken hinge damaged the cable. Also, it’s possible the video cable got pulled from the connector on the LCD screen. Try reconnecting the cable, so it makes good contact with the screen.
If reconnecting the cable fixes the video problem, all you have to do is replace the broken hinges.
September 28th, 2008 at 8:04 am
I’m repairing an M55 for a friend. The video is intermittent but mostly absent. It’s a black screen with the back light on. When I unplug and plug the monitor cable you can see the video momentarily. I checked all the connections and they are tight. Any ideas as to what could be the issue?
Thanks, Jim
September 29th, 2008 at 9:12 pm
Jim,
Can you get the video if you move the video cable? I’m thinking maybe the video cable is bad and it’s shorted inside.
Did you test the laptop with an external monitor? Is the external video output working fine?
September 30th, 2008 at 1:18 pm
Strangeness continues….from the top…
User told me that it sounded like the computer was starting but nothing appeared on screen. I get the laptop home and….it boots up fine, I can see the screen.
I take it apart to check connections. ribbon to back of monitor is tight, ribbon to motherboard is tight. Put it back together. I walk it around a bit and jostle it to recreate ‘light travel’. I put it down, pick it up, repeat.
Start it back up, no monitor, but there is a back light. Take it apart, connections solid. When I do unplug/plug the cable from the motherboard the monitor does flicker back on.
I just plugged in an external monitor and that comes up fine. I hit fn-f5 and that cycles through the monitors and the laptop screen does come on. I unplugged the external, shut down the notebook and came back 5 minutes later and it turns on fine even without the external monitor.
Thoughts?
October 9th, 2008 at 8:34 pm
Hey!
I attempted to fix my laptop screen as well. The new screen lit up completely white but there was no picture. I checked all the connections and tried again with no luck.
My old screen worked on one side where you could see the screen properly. I reinstalled the old screen so I could return the defective one and now this screen is not working either!? The screen is completely white…even the undamaged part! Does this mean the new screen is not defective after all? I did have some trouble connecting the “visual” port or whatever…
Please help!! I am sick of this bulky monitor and would like nothing more than a fully functioning laptop! : ) Thanks!
October 12th, 2008 at 10:32 pm
Kaitlin,
It’s possible you accidentally damaged the video cable while replacing the LCD screen. This is just a guess.

Hello
I purchase new lcd screen Samsung LTN150P2-L01, which was delivered with inverter (Ambit Rev:5 K021031.00, K021032.00, K021033.00) its SXGA+, my old, original screen was LG PHILIPS LP150X08 with the TDK inverter (TDK TBD281NR-1 EA12B281T).
The problem is that mam laptop compaq nx6310 has got output for inverter with 6 pin’s (like with old TDK which has 6-pin on input) , and my new inverter (which was delivered with new lcd screen) has got 16-pin input. Ofcource i can connect my new lcd screen to the old inverter, but what is the risk i damage the lcd or whole laptop (montherboard etc) ? How check compatibility of those two inverters?
Thanks
October 18th, 2008 at 1:39 pm
I recently purchased a new LTN140P2-LO1 screen as well to replace the one i had broke. I took it apart…put in the new monitor following instructions and when i plug it in I see a faint “HP: logo that pops up and then fades then the screen is black. I tried to plug in the old monitor and the same thing happend. I plugged it in following instructions and double checked the video cable connection. Did i somehow damage the video cable?
October 21st, 2008 at 8:23 am
All… don’t laugh here… I needed to replace the LCD on my Dell D630 so I bought the matching part # off Ebay. When it arrived, I went to install it only to find it had no screw holes for the inverter I was going to use off my old LCD display (the inverter was working fine so I was going to salvage it). So, I email the Ebay seller about not having anywhere to attach the inverter and they reply to tell me that my model doesn’t need the inverter… it will work just fine without it. I can’t see why Dell would put a part that isn’t needed in a laptop… they are too cheap for that!
Am I crazy? Is the Ebay seller?
Thanks!
November 3rd, 2008 at 7:27 pm
I bought a new replacement Inspiron E1405 screen on Ebay. I replaced my old one. When the monitor came on it showed the Dell logo and I was happy but then when the computer went to desktop I have a fragmented screen and when the mouse moves to the right side of the screen it flickers. Does anypne have any ideas? Thanks

Hi all,
I want to ask a question. I have a Toshiba A200 with a damaged screen (15,4″). I have found a same size screen from an Acer 1670 laptop.
Should I be able to fit it in my laptop? I am asking, because the Acer one will cost half the amount of a new one from Ebay.
In general, is there a way to make sure that the Acer screen is compatible before I buy it?
November 24th, 2008 at 11:39 am
Hey,
The backlight to the new and the old screen don’t work anymore, all the cables are connected correctly, but the backlight still does not work. Is there something else that could be wrong with my laptop? such as unplugged cables inside the main board?
Thanks if someone could help me out…I’ve been trying to find some place to fix my laptop, but then I can’t find out answers.

December 7th, 2008 at 11:41 am
Shaukat,
Take a closer look at the laptop screen under bright light. Is it completely blank or you still can see a very very dim image.
If there is a dim image, most likely your problem is related to the inverter board. In this case I would try replacing the inverter first.
December 17th, 2008 at 4:32 pm
I have a philips freevent x59. The old screen worked but no backlight. The invertor has been changed and the screen has just been replaced with a new one. It has the same problem. Still no backlight. Is there anything else. I have done the obvious and checked the connections
December 18th, 2008 at 6:35 pm
I have an Acer Aspire 3610, the LCD on it sort of works, it comes on bright white when switched on and then slowly fades in to the normal bios screen (no hdd installed atm) once it’s faded in it works in very very slow motion, i tested it by putting a windows installation disk in and going through the first couple of steps. I could see the WIndows installation menu and the mouse cursor arrow, as i moved the mouse the arrow moved really slowly across the screen, leaving a trail behind it. I’ve plugged a normal monitor in and that worked perfect. So, i’ve ordered a new ribbon cable for the monitor as i suspect that may be where the fault is, do you think that could be it?
January 29th, 2009 at 6:16 am
Hi I have an old HP ZD7000 that had a cracked screen. IT had the partnumber LP171W01(A4)(K1) I replaced it with a compatible one. The backlight comes on but there is no bios screen. I connect the old screen and it works just fine. Aside from the replacement being bad, is there anything else that could be wrong?
February 2nd, 2009 at 10:52 pm
Rick_D,
1. Bad replacement screen.
2. Incompatible replacement screen. Maybe it requires a different video cable. Some LCD screen might look the same but they requires a different harness.

My laptop is a fujisu lifebok e8000 and it uses a samsung LTN150XG-02 glossy LCD screen. i wanted to replace it with a LTN150XG-01 matte screen but it doesnt work. everything works fine as swapped back the old one to post this. Do i have to get the EXACT same model as replacement? or do i have to change the inverter to make it compatible with the new screen? thanks!
March 17th, 2009 at 6:44 am
We have ordered a screen from screenaid and need to find a resolution for our customer. The old screen has a slot on each side of the adapter. But the new screen does not therefore the sodder joints wont allow the video connector to slide into the connector. the video connector has a clip on each side so it has to go past the adapter. Please advice

Hi,
I ordered the same model as the one that broke, connected it, but after 1 second of powering my pc shutdown. After checking it seems the screen I received wasn’t the one I had ordered. Now the laptop doesn’t react to the power button at all.
Do you have any idea what could be damaged and why it was damaged?
Thanks
April 4th, 2009 at 2:55 am
Hi,
I changed my screen for one I thought was identical. When powering up, my laptop shutdown for good. It seems that I should have checked the screen I had received was the one I had ordered
Now my laptop doesn’t react to the powerup button anymore. Do you have any idea what I could have damaged, and why?
Thanks
April 4th, 2009 at 6:57 pm

Repairing LCD is not something you can do it yourself. Atleast not for the people who are not computer savvy. Finding a right technician makes all the difference..
April 15th, 2009 at 7:26 am
Mr.LCDrepair,
I agree but not with the whole statement.
I wouldn’t recommend repairing LCDs for people without experience, but replacing the LCD is a different story. It’s not as difficult as it looks like. If you are careful enough, everything should be fine.

I JUST BUY A NEW LCD SCREEN FOR MY LAPTOP I HAVE AVERATEC 4100
AND THE SCREEN DONT SEE ANY IMAGE JUST BLANK I PUT BACK THE OLD ONE AND DO THE SAME THING NO IMAGE I DONT NO WHAT HAPHEN BUT I CONNECT TO VIDEO PORT OF MY LCD TV AND WORKS FINE BUT NOT ON MY LAPTOP PLEASE HELP THANK YOU
April 27th, 2009 at 9:46 pm
RAUL,
1. Make sure the LCD cable is properly connected to the motherboard.
2. Take a look inside the video connector on the motherboard. Make sure all pins inside are straight and there are no bent/damaged pins. Very carefully straighten the damaged pins if you find any.
3. Could be defective video cable.
April 29th, 2009 at 11:57 am
I replaced the LCD screen in a Toshiba Satellite Pro 6100 with a replacement screen for that model. After connecting cables and powering up, it switches from gray, grayscale, red, green, blue, and then white to black 4 times quickly. Then it repeats over and over. I first thought the computer was just calibrating the color on the new screen, but it never ends. I took the screen off and reconnected the cables to make sure they were seated well. Same result. Any ideas?
April 29th, 2009 at 12:40 pm
Ed Aycock,
What was wrong with the old screen?
Did you test the laptop with an external monitor? Does it display image on the external monitor?
Take a look inside the video connector on the motherboard/video card. Make sure all pins are straight and there are no damaged pins. Maybe you accidentally damaged pins inside the connector?
April 30th, 2009 at 6:49 am
What was wrong with the old screen?

The old screen was cracked. I tested with an external monitor and the display was perfect.
Take a look inside the video connector on the motherboard/video card. Make sure all pins are straight and there are no damaged pins. Maybe you accidentally damaged pins inside the connector?
I checked pins inside the screen’s connector and they look good. I checked the pins on the cable and cleaned them. I don’t have the laptop apart to address the video card or motherboard. The screen is powering up, but not receiving image or signal from the computer. It is going through the color scale like a test pattern. I gave the right part number to the vendor, but maybe I just got a bad replacement screen.

Hi, I just replaced the LCD for my dell 1500, I can see that it works, but the computer keeps booting and rebooting in a loop. Help! It does it about 5-6 times then turns off. It goes to the XP screen then back to the Dell screen, then back to XP screen. I can’t get into the safe mode or set up menu even.
May 13th, 2009 at 12:34 pm
Misty,
Here’s something to try. Unplug the LCD cable from the motherboard and start the laptop with an external monitor. Do you still have the same rebooting problem even when the LCD is unplugged?
If yes, your problem is not related to the new LCD screen. There is something else going on inside the laptop.
June 2nd, 2009 at 3:19 pm
I had a dc jack replaced on a laptop. I shipped the MB when it cam back I put it back together. the HDD spins, HDD light goes on then off but nothing shows on the screen. I checked all the cable several times and disassebled the laptop at least 4 times. I don’t hear the fan spinning or cd rom.

Hi,
I have a Fujitsu Siemens Amilo Pro V2010 which shows a dark screen with a faint image. I have tried the screen attached to another (working) V2010 and it works. I then checked the broken V2010 with an external monitor and that works as well. Is it possible that the video chip could be damaged in a way to make it look like a backlight/inverter problem?
Yours in puzzlement,

I replaced my lcd screen in my Dell Inspiron 8600, but the screen cycles through colors of red, blue, green, and white. When I connect to an external lcd it shows a blue screen and reports that a hardware error has occurred.
August 20th, 2009 at 12:36 pm
I am with purple vertical stripes on my screen. Follow the link for the problem with images, I believe to be the screen, but told me to be the reverse lcd or flat cable.

I have two broken laptops: Packard Bell with dead motherboard and Dell with screen that shows faint image. I’ve tried to fix Dell by replacing screen and inverter bought on eBay, but it did not help. I wonder if I can take the screen, inverter and cable from Packard Bell and use them all in Dell?
Thank you in advance
August 26th, 2009 at 10:59 pm
Max,
Most likely not. These are two different models.
August 26th, 2009 at 11:17 pm
Almeida C.,
It’s not the inverter, that’s for sure.
Can you test the laptop with an external monitor? Are you getting same problem on the external video or not?
If the same stripes appear on both, internal and external screens, you have a bad video card.
If stripes appear only on the laptop screen and external video works fine, it’s possible you have bad LCD screen (more likely) or faulty cable (less likely).
September 22nd, 2009 at 2:56 am
Hi
I’ve replaced the screen on my sons girlfriends laptop (MSI PR210 YA Edition Pink Laptop) but it now has little flashes of coloured lines going down the screen. I can see everything okay but the lines are really annoying!
I’ve checked and it’s the right screen etc and when I connected it to my monitor the lines are not there.
I’ve checked all the cables and they all seem fine, but i’ve noticed that the metal lip on top of the video cable lead isn’t touching the connection on the screen. i’m talking about a miniscule gap but I wondered if they need to be touching to get a complete connection.
September 22nd, 2009 at 10:44 am
cliff,
That means the video card works properly and the problem is somewhere inside the display panel.
1. Try reconnecting the video cable on the LCD screen if you haven’t done it already. It’s possible that the video cable is not making good contact with the connector on the LCD screen.
2. Access the video cable and move it a little bit while the laptop is on. Will it change anything on the screen? If moving the cable affects image on the screen, it’s possible you have a faulty video cable.
3. Could be defective LCD screen.
September 26th, 2009 at 4:47 pm
A friend has a Toshiba P200 with a problematic screen, first the keyboard went, then a couple of weeks later suddenly the LCD screen stopped working for no apparent reason, an image can be obtained on an external mointor. He’s rplaced the keyboard and a damaged monitor cable to no avail, then the inverter, and finally the screen each with no success, we’ve upgraded the memory and hard drive in the process so in my opinion that rules out any software issues, advice please…
October 13th, 2009 at 5:55 am
Machine:
Lenovo 3000 N200 Model 0769-AH8
Problem:
I had my original LCD screen broken – LTN154X3-L06 / LTN154X3S2LV3.1 (on PCB)
so ordered one from a US based online store. The new one i got has this written on its pcb: LTN154X3S4LV3.2 (on PCB) and LTN154AT07-002 on a white sticker.
The new screen has same size and resolution and backlight type.
After changing the LCD, I get contents only on 2/3 of the screen…1/3 of the right width of the screen is filled with white and other colored vertical lines.
(so from left end to more than half towards right, the picture/desktop is perfect like nothing has happened. Rest of the screen on right has multi-colored vertical lines)
Any suggestion what is the problem? are the two screens not compatible? Any help will be greatly appreciated…I am in deep trouble due to this problem.
Thanks.
Soni
October 13th, 2009 at 8:30 am
Mukesh Soni,
I think you got a defective LCD screen. Your description sounds like a bad screen.
Contact the seller and replace the screen with another one. Hopefully, you still have warranty.
October 19th, 2009 at 12:12 pm
Hi!
I have a Thinkpad Z61m with a blank screen and no backlight.. An external monitor works perfect but i can’t even see the internal monitor in device manager. – Is it the LCD or the video card? – Thanks
October 25th, 2009 at 9:58 pm
Christian HC,
It’s hard to tell. Are you sure that the laptop screen is completely blank? Maybe the image is still there but it’s just very dark? Take a closer look.
Try to switch video from the external to internal mode using Fn+F7 key shortcut.
October 29th, 2009 at 11:06 am
I had half a screen on my dell vostro 1000. I saw an lcd
replacement advertised for less than dell. When I look at
the replacement it has no screw holes on the frame for the
inverter or the piece on top (mounting bracket )that the bezel is attached to.
Also white tape that says “Do Not Touch” covers the area
of the frame on top were the mounting bracket would go.
How can this be fixed. Does the white tape get pulled back
and the old metal frame removed and goe on the replacement lcd?
thanks
October 29th, 2009 at 8:19 pm
James,
Apparently you are looking at a wrong screen. Try to find a new LCD screen that matches your screen.
It’s normal. You’ll find this warning on most LCD screens.
I doubt it. Most likely the mounting bracket is permanently soldered to the frame.
I had a problem like that last week. I was replacing the LCD screen on a Gateway laptop and purchased a new one with exactly the same model number, but… the revision was different. Instead of Rev.C1 I purchased Rev.C2
The new revision had two mounting brackets on the top and bottom and the screen didn’t fit into the case. I had to send this screen back and replace it with Rev.C1 screen.

Hi,
Im trying to replace LCD on asus laptop but there is no display. I have noticed that a pin from ribbon connector is not there so do you think that could be the issue?
November 9th, 2009 at 10:33 pm
Hamid,
It’s possible. Can you get at least the backlight?
November 10th, 2009 at 5:33 am
I replaced an LCD on a Dell Inspiron 1525. I found it online for $120 shipped. It’s a Samsung LCD panel, 1280×800 WXGA 15.4″ screen. It fits into the Dell fine, but there was no bracket for the inverter board. I was able to use plyers and destroy the old screen (was already broke) to get the inverter bracket off that, then use a hammer to straighten it out. I got everything in, and I even had video for a few minutes until I powered it down and shut it off. Now it’s back together and I get no video. The backlight comes on, and you can see it flash when I use FN+F8 to cycle internal / external video. External monitors work fine also. I opened it back up (which is a pain I might add…) and reseated the cables. Still the only thing that comes on is the backlight. I just ordered a new LCD signal cable. Do you think that could be the problem? The LCD signal cable was attached with industrial strength tape on the old panel’s connector. I wonder if prying this tape up also damaged the signal cable.
The monitors aren’t exactly the same, but they state they are for Dell Inspiron 1525’s. Same resolution, same size same signal connector, same mounting holes same brand (Samsung). The only thing different is the placement of a 1cm connector (which is also on the broken LCD) which is not used at all. Also the part number differs (LTN154X3-LOD vs. LTN154AT10) but the thing is I saw the Vista boot screen when I powered it up (while still disassembled).

Keith,
Have you tried reconnecting the video cable on the motherobard (or video card)? Maybe you accidentally pulled the cable from the connector while taking apart the display panel?

Yes. I reseated the cable. I ordered a new cable and will try that as well. Additionally I heard that some people may have issues with a little switch that detects when the laptop is closed. I will look for that as well if I can find it. They say it’s near the hinges.

Well I got the new cable today. Same results. Backlight is A OK. No video on the screen. Screen senses cable because when the cable is removed the screen turns pure white.
Video is fine through the VGA and HDMI outputs.
The replacement screen is going back. I hope they will honor it. It was purchased from eTech.com

Hi. I have 2 same machines and one of them had broken screen. I took a screen from the working one with all cables conencted etc. and ther eis no backlight there. I can see very dark icons. When the screen comes back to it’s parent it works ok. Is tehre anything else apart of cables,inverter, incompatible screen, that can cause such a behaviour?

kukazu,
Are you sure that the laptop with broken screen works fine? Can you get light on the broken screen and the laptop is turned on?
