Brief summary of the past:
1. Screen started displaying horizontal lines.But still worked after touching here and there. I therefor assumed that the screen is fine, and the cable is the problem.
2. Bought a new cable.
3. This didn't fix it.
so I assumed it was the top part of the screen, where the cable connects to the lcd.
So i bough a new screen.
4. this didn't fix it as well.
so now i have a new screen, and still ALL I SEE IS WHITE LIGHT coming out of it.
should I now assume it's this little part that the cable ALSO connects to?
i am talking about the part that sits under the screen, and there are 2 cables connected to it from each side: one from the lcd panel itself, and one from the video card (as the video cable has this intersection, where 1 becomes 2).

I have some news.
So here is what I thought of: I downloaded a LIVE CD of Linux Puppy (knowing it can fully run from the CD and boot from it).
I than managed to get the external monitor working (once puppy ran), BUT, here is what I get:
please see video:
Please analyze - does this shade new light on the issue?

it's weird, because I have tried to reload puppy, and it won't show a picture this time (tried it 3 times). And I know it loaded, because I can hear the CD working and the HDD light flashing.
Why would it show up once, and now it won't?
Yes, the LCD did cam bear. That is, no video cable (if that's what you mean).
I am really lost.

Yes, weird. It may be the graphics hardware on the motherboard. Inverter is possible also, I guess.
I have no further ideas at this time, sorry.
If I think of any, I will post or PM you.

looks like an inverter problem . Some guy i know had the same problem and he said it was the inverter ... i hope so , because if it's the motherboard you'll be hard pressed i think to get a new one for a good price ...

With a bad inverter, the backlight would not light up.
That's my understanding, at least.
So, if everything else is correct, cables, panel is right model,
etc., you may be right. GPU or other motherboard problem.

Yes. I am also assuming this (tell me if correctly so): when a laptop is connected to an external monitor, the inverter becomes irrelevant (that is, the inverter is not needed - not used - to produce the picture).
If this assumption is right, than it means that even if the laptop's display is malfunctioning, I would still get an image from the external display.
Is this a right assumption?
(i am only going over these issues so I will know i am not giving up on my main - and best - computer of the house)
