I had two broken lcd panel of laptops, and have been looking at this
for two weeks, and I didn't know anything at all when I started.
On the first one I had to replace the panel, and I managed to
misconnect the inverter before powering up, and I am pretty sure I
killed it, so I will have to replace that now. But the good part is
that the panel was just 80 euros and pretty easy to replace and it
would all work fine if I was not completely handicapped.
This site helped me a lot :
On the second one, I thought and hoped the problem was just the
inverter. I bought a new one only to realize the old one was perfectly
fine. So now I am pretty sure it's the backlight.
I have been looking several times at this article :
But I am 99% sure I will either break something while trying to
disassemble or never manage to assemble it back. so I will just buy a
new panel, that's the easiest :)
On the other hand, if you know you are going to buy a new panel, you
might have nothing to lose trying to fix the old one and possibly
