Question about Dell E151FP 15" Active Matrix TFT LCD Monitor
Screen now goes white immediately it the beginning it would go white after it was in use for a while. Now it is almost immediately. I have removed the cover from the back of the LCD panel. However I do not see any obvious signs of a component being bad....can someone direct me to the part that usually is the issue? I have two fo these monitors currently with this problem. Unfortunately I have several of these in use and I am concerned they too will start having the same problem.
thanks in advance for any help I have the same problem. When my monitor comes on it is all white and stays that way. I have connected it to a different computor and the problem is still there. I'm looking for a higher technical explanation of the problem. I have a Dell 15" LCD that I just got from someone on Freecycle. It practically seems like some kind of RPG (game) where you just keep levelling up to more and more difficult problems. Past monitors have had obvious damage, a blown inverter, power board, etc., but this is a stumper.
It doesn't always start up white. And out of nowhere it'll just fully kick in and out... suddenly BAM, all white. Then I can just leave it on white for a while, and it'll go back to the normal screen. No amount of powering-on-and-off will convince it otherwise. No bashing it upside the head. Nothing is overheating either. It's got no rhyme or reason... it'll do it cold, warm, been on for hours or just minutes. It'll just go all white all of a sudden.
I sort of guess bad capacitors since that seems to always fix my electronics quirks (like the "close cover" error on the LaserJet IIP caused by a bad capacitor on the density control PCB). But is there anyone that can put a more direct finger on the problem?
The problem with most LCD monitors that go white are one or more of the following in order:
1. Bad or loose VGA/DVI connection cable
2. Bad power inverter board. (Internal part: can be replaced)
3. Bad power supply.
Hope this helps you.
