The problem can be the lamp assemblies also, it will be hard to verify unless you have test lamps to find out if it is the lamps or the inverter problem, that is one of the first thing I check first if the board has no sign of damage. I save a lot of lamp assemblies for testing purpose.

Dell monitor screen suddenly went white. Can it be fixed?


I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

2208wfpt flickering, not staying on


The problem is in the power supply/inverter board, there are more than likely one or more bad capacitors that open, "sometimes bulges at top" the other concern is one of the inverter transformers may be bad, or a failing backlight behind the display.

The problem is caused by one or more capacitors that have opened in the power supply/inverter board, sometimes they show a bulge at the top making it easier to spot.

The Dell AS 501 monitor display comes and goes off in seconds. If I switch off and on again, the display comes back and goes off again in less than a second. I repeat this as many times the same monitor...


This sounds like the power inverter is failed.. It's what pumps up the power for the light in the monitor.
You could try unplug the sound bar from the back of monitor if you have the sound bar installed. Just a maybe..
To fix the inverter (replace) is usually better to buy newmonitor unless you do it your self.
The defective LCD Backlight inverter will cause the following symptoms:
  • No Display, but Power Indicate light stay on green (Or Blue).
  • Screen flash on and off and the power indicate light stays on green (or Blue).
  • Dim Display

DELL 2208WFP LCD-Comes on normally, but almost immediately goes dark You can see something on the screen if you look closely. Turn it off and back on you see it then dark. any help?


Hello,

I believe the power led button is still on while the screen goes dark, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes dark after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes dark.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

Dell Monitor won't stay on


When it goes black, does the power buton stay green or is it orange? If it's orange, the power supply/inverter is your main culprit. If the power button stays green, it sounds like the backlight for the display is bad. Either way, unless you have parts for the same monitor laying around to swap out, you're due for a new monitor. The good news- with the economy in the tank, you can search online and find some reputable vendors selling nicely sized screens for less than $100! Heck, I've even seen a 22" for $129 (once but it was there).
