We managed to replace the backlight in my Dell inspiron 6000 but the screen does not light up evenly. It is bright at the bottom and darker at the top. Also the brightness adjustment does not work.

It’s possible that the backlight lamp is not seated correctly inside the LCD screen.

It is bright at the bottom and darker at the top. Also the brightness adjustment does not work. I would greatly appreciate any comments from any one who has had the same problem. By the way I also replaced the inverter at the same time so i know it is working. Many thanks We managed to replace the backlight in my Dell inspiron 6000 but the screen does not light up evenly.

I have been thinking it is the LCD, too. But like you say It would be wise to check the cable connections to the video card/motherboard. I guess it will just take diving into the lower half of the laptop to learn how to access those connections. I assume by removing the keyboard. I may have to return for more questions later. If any new advise and wisdom is out there for me, please don't hesitate. I am not a bad do it my self guy, but this laptop/electronics thing is not my comfort area at all. But I think I will be getting better acquainted real soon. Than you again, Keven. cj2600, thank you. I have been thinking it is the LCD, too.

I think he was joking. :) Or maybe he wasn't a technician at all. Your problem is not related to the inverter board, that's for sure. Let me explain myself. The inverter board is a power supply for the backlight lamp inside the LCD screen. All it does is converting low voltage DC power into high voltage AC. If you can see the top 1/3 of the scree and it's bright, it means the backlight lamp and inverter board work properly. When inverter fails, the ENTIRE screen is completely dark. I think you have damaged the LCD screen. Keven,

It looks great up there. But the bottom two thirds is completely gray. I light gray, and has no image showing through at all. This happened about a year ago. I can hook up to an external monitor and with good results, but it takes a lot of guessing to find the right place to click on the laptop monitor to open the right controls for setting the laptop to work on the ext. monitor. But that is not the question I have. I talked to a gateway service tech on the phone. Even though my warranty is long over he was nice enough to tell me he thought my problem is for sure the back light inverter. He told me it would cost 150-200 to fix. I just today looked and found ebay has them for under $10.00. I even opened the screen and verified the cables are connected on both ends and also the p/n. I am not sure how to check the cable as it is connected to the mother board. Anyway, what do you think my problem is? Please email your reply if possible. But I am going to book mark this site too.

Depending on how far back it is moved the screen will either go mostly dark with a few lines showing (no image) or it will still have all colors Image can mot be seen). In only 1 out of 100 times can you move the screen back to get the correct image. The solution to getting your screen back is make sure it is displaying in color mode (Not Dark) 1. Put it to sleep and then wake it up (100% recovery) 2. Alt Ctrl Delete (50-75% recovery) 3. Alt Ctrl Delete then if still unreadable arrow key down once and enter (Switch User) (90-95% recovery) Notes a. This only happens when you move the screen. b. It works perfectly with ext monitor even when the screen is dark. c. I have taken the screen cover off and determined the issue is under the left side hinge where the cable from the screen (not the cable to the invertor) goes into the motherboard. My questions are: 1. If it is a short then why does it come back to life after the above procedures. Wouldn't it stay off until the short was resolved? 2. Can I go into the connection on the MB or is this better left to laptop techs? Thanks for your help and thanks for the service you provide here.
