Hi all. I recently got a thinkpad that wouldn't boot. It turned out the motherboard was bad. I put it back together and the screen no longer works. When it is switched on there is a bit of flashing here and there like it is doing something and then it just stays black. The computer works on a monitor but not on the screen. I bought another thinkpad and swapped the screen but same deal. I know the fault lies in the screen area somewhere but I'm pretty sure the ribbon is ok and plugged in properly. Could the inverter cause this and if so how did it go wrong? I didn't touch or damage any components in the screen casing although I have taken it apart.
Also I havn't put all the screws back in while testing it, could this affect it's operation with an earth problem or something?
Any ides appriciated.
Thanks.

Sounds like me when I rebuild a carburetor and I have a bunch of parts left :thumbsup: It's possible. When you changed screens did you reuse the wiring harness? the wire might have kinked and broke even if the insulation is intact

I think, Mark that you've hit the nail on the head. I cannot possibly see any other reason. Now to search ebay for a replacement, joy!
Thanks for your input.
Phill.
