Help needed pls - LCD, inverter

[jw2k_fr]

Hi

I have an old Dell Inspiron 5000e which has a display problem.

The machine powers up and will boot to XP, but the display is only visible on an external monitor - the laptop's display panel goes to a uniformly white screen (although when looking down almost from directly above the display I can see vertical lines in the white screen).

As I understand it, the problem could be one of the following:

1) There could be a problem with a loose cable or connection from the graphics card to the panel (have checked, couldn't see anything wrong)

2) It could be a problem with the inverter

3) It could be a faulty panel

I understand that the inverter is responsible for generating an AC supply for the panel but due to the fact that the panel lights, is the problem likely to be with the inverter or the panel?

Thanks in advance
James

Could be a damaged cable.. since they are twisted every time you open and close the lid... they're pretty cheap to replace.. I would try that first.

Weenis: Have checked cables and all looks okay. I may yet replace them, but I have a feeling that's not the problem.

Any other suggestions?

Thanks

Well as you mentioned it could be the inverter, it doesn't seem like that.. because you said it can boot to a white screen.. so I'm sticking with bad cable, or dead display.
