Laptop Monitor dying, want a second opinion

[shavale]

Hello, my GF has a Dell Latitude D600 (very old) laptop that has been working fine for a few years when she suddenly started having a weird problem.

Her screen goes lighter, then darker, then lighter again, and then black.

If I press the "closed lid" button, wait for the laptop to enter standby mode and then tap the button again the problem goes away for a little while.

I'm a computer technician by trade, and I was considering telling her to replace the screen but first I wanted to be sure that it was the monitor's fault and not something else. My line of reasoning was that the wires that connect the monitor to the motherboard might be worn out but without stripping them I cannot be 100% sure.

How does it behave when connected to an exterior monitor? Have you tested the inverter?

The inverter board provides power for the CCFL tube that back lights the LCD screen.

Hi

Thats a VERY old lappy lol.....

Its around an 80% chance its the screen ..about 19% (roughly lol) its the Inverter and 1% cables...

All the best Brett

Hmmm, the inverter board seems likely... I hadn't thought of that. I might try replacing it, ty!
