Philips h12y (Vista) – old chimei screen damaged – part viewable. merchant says new LG screen compatible – but just get white screen – external monitor fine. Put old screen back – now also just white (both can be turned off with Fn/F3 keys). Double checked connections at both ends, cable doesn’t appear damaged Do I change inverter and/or cable? If new screen incompatible, has it done any irreversible damage? How can I check if LG screen is truly compatible (with inverter?)?

remark,

But after replace exist only backlight,no imagr.What is the problem,incompatible LCD? Or something else?

Make sure the video cable is plugged correctly into the LCD screen. Try reconnecting the video cable just in case.

I’m having similar issues with my Dell Vostro 1500. I had the 1280×800 resolution screen, but my kids cracked it so I ordered one and it came yesterday. I took the old screen out and unpacked the new screen and have the exact same problem y’all are seeing. The new screen has no mounting holes for the inverter bracket at the bottom and upper screen to back plate bracket at the top. Both of these brackets are screwed onto the screen.

I installed it loose and booted the computer. I got 8 Dell Windows staring back at me, then 8 Windows 7 boot ups then everything goes blank. I re-hooked up the old screen and it works just fine so it’s not the cable. I also tried the new inverter that came with the screen and the problem still followed the screen.

The OEM screen is a Chunghwa CLAA154WB08A. The new one that I got was a Chi Mei N154I5-L01

Hi,

I replaced my dell 17″ WUXGA with WXGA (sharp to LG ) and I used my original inverter board.

It works only while it boots and in safe mode (in safe mode it loads standard VGA drivers). If it loads full Nvidia drivers for my go7900gs it looks its on but doesn’t show anything. I tired extending it onto my TV and it works fine on TV but nothing on LCD screen.

it seems that graphic drivers or graphic bios is blocking the new screen. I also read somewhere that all manufacturers block screens that are not for their line of laptops through bios but i cannot confirm it.

Can anyone help please.

thx in advance

p.s. windows are not the issues since i reinstalled them (win7 ultimate) and LCD screen works while installing but as soon as I update graphic driver it only works on TV or external monitor)

Hello,

I replaced my laptop screen and now the computer has no power at all and wont even come on. I reconnected the battery and on my ac adapter the light is on until I plug it into the computer and then it goes off. I checked to make sure all connection where good and everything looked good. I even tried my old one and now it wont work??
