Monitor turns on and off?

The LED light goes from green, to orange, to OFF repeadly.  I unplugged the monitor for a week (from power and computer) and when I plugged it back in it seemed to be working. I unplugged the computer cable and I saw the Self-Test so I thought that the monitor was fine. A couple hours past by and the monitor start doing the same thing. I can see the Self-Test if I unplugged the computer cable, it doesn't switch on/off. I change the cable from the other monitor and the monitor worked for a couple hours and it quit working. This monitor has only  VGA connection. I had an extra new cable so I changed it but it made no difference.

What color is the power button LED when switching on/off? Are you saying during the Self-Test that it doesn't switch on/off? Use the monitor cable from the other monitor on the Dell. Waht happens?

I can not see my Self Test anymore when switch on/off. I unplugged the cable and the monitor keep going on/off.

If under warranty, it should be replaced. I have to check the warranty status. Send me the following in a private conversation (Click my name, click Send a Message) -

Hi Chris

All of the sudden my LED display began turning on and off by itself. Even when the computer is not on, the LED display will just turn on. While I am using the computer, the LED display will just turn off. Any thoughts?
