The problem I'm having now is with an IBM Think pad R51 15" diagonal screen. First let me say that from lots of research it sounds like it might be the LCD inverter.
During boot up, the screen won't stay on until Windows comes up. After it has time to finish booting up, I can see the desktop icons using a flashlight. I can then take a small screwdriver and press the little recessed button that the lid presses as it is closed and the screen will come on again for about 2 seconds and it starts all over again.
I can connect the laptop to an external monitor and all works well.
I ordered an inverter that looks identical to the original. It was supposed to be for an R51 ThinkPad but when I compared the p/n and FRU #, the two inverters are not the same. I changed out the inverters but the screen will not stay on... Is it likely that I received a bad inverter or either the variation in the part numbers is the problem?
The numbers on my original LCD inverter are: p/n 91P 7299
FRU 91P 7336 EC J18008.
The numbers on the replacement inverter that I ordered and installed are: p/n 39T0369 FRU# 39T0368 EC J76566K.
Thanks for your time,
