Dell LCD monitor flashes white every second, and then goes black
My dell LCD 17" monitor flashes white every second, and then goes black. The green LED also flashes orange. The only way I was able to make it temporairily stop was by giving it a good smack on the back of the monitor. Initially, it would only occur when the computer went into sleep mode, and then trying to come back, this would occur.
As time passed, the flahing got worse to the point where every five minutes this would occur. I broke down and got a new one (the warrenty expired about 2 months before), but I would like to fix the monitor if at all possible without having to spend a lot of money. However, I do not know where to begin. I have it apart, but cant find any obvious problems.
Hope someone can help!! Thanks in advance.

Take a very good look at the power supply capacitors. Are any of the tops of the electrolytic capacitors domed? If you replace them, use a high frequency high temprature replacement to prevent a repeat failure. Don't use a standard 85 degree cap. It won't last.

Hi my name is Rain.
Ok so that im clear on the problem. your monitor will come on but in a matter of seconds it goes to a black screen?
If this is the problem. The answers you seek will most likely
be in your video card.
Try this test:
Unplug monitor from the computer.
Turn on monitor .
Look for monitor self test screen.
If you see the monitors self test screen then your problem indeed is
the video card . You will need to replace the video card inside of the computer.
Hi Gaz, First, verify the monitor is functional. Monitor STFC (Self Test Feature Check) Turn off the monitor Plug the monitor power cord directly into the wall socket to remove any surge protectors or APCs from the troubleshooting equation Unplug the monitor video cable from the back of the computer Turn on the monitor The floating dialog box should appear on screen against a black background. If the issue appears during the STFC, the monitor is defective. What are the results please?

You said the monitor is 2 years old. Do you have the original order number still? Depending on how you purchased the monitor it may have up to a 3 year manufacturer warranty and I may be able to replace it if it is within that warranty period.
Please email me at Customer_Advocate@Dell.com if you can locate the order number and I'll be glad to see if its still under the manufacturer warranty. Include my first name (Todd) in the subject line of the email so it can quickly be routed through to me, and include the order or customer number if you have it.
