I’ve searched a number of sites for different laptop repair/disassembly manuals and while I’ve found a few this is by far the most comprehensive. Thanks for the post and thanks for your efforts.
( If you have any info on a quick fix for a BIOS/startup password reset please let me know. I can’t get past the power on or even into the BIOS.)

Thanks

These are a great set of instructions. I have two T43’s. The screen on one went black. Anyway, while replacing the LCD I have managed to damage the LCD connecter cable and now need some advice on how to replace the cable. At the moment I have one machine that I can cannabalise.

I would appreciate some similar set of instructions as above.

Thanks

In reply to jthendrix. @ jthendrix, Most likely this is inverter failure or CCFL failure (backlight lamp inside the screen). Cannot tell without testing the laptop with another inverter or lamp. If you have to guess, try replacing the inverter board first. There is a good chance you'll fix the problem.

right now my t43p’s screen goes out regularly, every 2-5minutes. sometimes i see something faint in the background, more likely if i have white-colored windows opened when it happens. but most of the time i see nothing at all back there. and my usually white letters aren’t reddish or pinkish at all. i can’t figure it out. i’ve gone through BIOS tweaks, multiple scans for malware, going through settings, but nothing so far, and it’s been almost 4 days of constant approaches. can anyone help me out with this? please do if you can :o) thanks!

Thanks for such a great posting. I just replaced my LCD screen on my t43p and everything was exactly as shown in the pictures, even the screen model number and FRU part number were identical. New screen works great. I was worried as I had no way of knowing if it was the screen back light or the inverter that was bad, but the way the symptoms were described (with the pink colors) fit what I was seeing so I took the chance. My screen had actually completely died (no light at all, even when first started up) but it had shown the pink color symptoms for a while before it died. It still worked fine on an external monitor though. The full replacement took less than an hour.

I just want to really thank you. I was looking for about 2 hours on how to find the panel model number for my screen and you really helped me out.

In reply to mikiki. mikiki, Unfortunately, there is no way to tell what is wrong without testing the laptop with another KNOWN GOOD SCREEN. It's possible that when you installed a "wrong" XGA screen you damaged something on the motherboard OR maybe fried the video cable.

Thanks for fast reply.

Notebook works ok with external monitor.
However, when i return both original SXGA screen with original cable, it still shuts down
immediatelly 3-5 seconds after I press power button. Same thing also happens with XGA screen from T42.

So, is motherboard damaged, how can I determine that?
Do you have any more clues after I provided to you with this info?

If i can be sure motherboard is not damaged I would by a new screen, however, if i cant determine if motherboard is damaged it would be too risky to buy a new screen.
