It started last week when after turning back on from sleep mode, the backlight turned on then off. I brought a light to it, and still saw an image so I suspected it was the backlight or power supply.
The next day, I took the case off and looked around a bit on the inside, but came to no solution.
Plugging it in, I found that the backlight worked again, though the picture was a little dark.
Two days later, the backlight again went out after I came back from sleep mode.
I turned it off and left it alone for a few hours. After this, I turned it back on, and the light worked again!
A day later, the same thing happened.
To recap, these are my symptoms:
1. Monitor's backlight does not turn on after coming back from sleep mode.
2. After turning the whole monitor off and letting it rest for a few hours, the backlight will turn on.
3. When the light is on, the picture is noticeably darker, but lightens after a few minutes. The light bleeding through the edges, as well.
It is a Dell E172FP.
I have an Nvidia GeForce 6800, if that matters.
Basically I want to know if this is at all a common problem, or at least a documented one, and any suggestions on what to do.
Thanks.
