Seen this before? Gradient to white

[Jamesah]

I'm looking at buying a broken Dell monitor and trying to repair it.



The brightness settings function. From what I can tell the backlight is still strong.

If it's bad caps then sweet. I can handle that. Has anyone seen this before? I know it's risky but it could be a steal if I fix it.

There a lot of members that would prefer you do not use in line pictures; suggest you use the managed attachments feature.
I have seen similar though not quite the same problem, with a with the ribbon cable from the logic board to the LCD panel. Try cleaning reseating the cable both ends.

I'll do that from now own. I'm on my iPad at the moment so I can't fix it. I think I'm gonna take the risk and see what happens. Hopefully it's fixable. Thanks for the response. I could see fixing caps and monitors becoming a hobby.

If you think there will be more monitors you will repairing, Even if you find this monitor not repairable you will still end up with some good parts. It is always good to have good ccfls around for testing.
Just don't mortgage the farm to buy it.

No, but I would be very surprised if this was due to a capacitor problem on the power supply/inverter board. Banding like that pretty much has to be on the video board or possibly in some logic in the panel itself. If it is cheap enough it might be worth getting for parts though. I suppose there is an outside chance the +5V from the PS is off due to capacitors, but I would not want to bet on it.

Yeah I do not think this is going to be a capacitor issue, unless it was bad capacitors to start with which caused damage to some other components.
