I recently purchased a new WXGA+ screen for my Dell XPS m1530 laptop. The old screen was cracked.
Upon installing the new screen it did not display. After some fiddling I finally got the screen to display, but it was very dim as if the inverter board were not working. I then replaced the battery and restarted the computer, only to have it refuse to display again.
I know the video card is not bad because it outputs to an external monitor just fine, and I am pretty sure the new screen is not bad considering that it worked at least once. I am a little lost here trying to figure out what exactly could be wrong.
To recap here are things that I have tried:
attaching new screen + new inverter = no signal
old screen and old inverter = no signal
removing power sources and removing excess charge via holding the power down.
I would have thought it was just a bad inverter board considering that it worked once but with no backlight, but now I am not getting any signal at all from either screen.
My last thought is that it might be the LVDS cable?
