Monitor goes off after only a few seconds. Blue light goes orange.

Try a different monitor, check the connections to the pc. When the monitor light changes to orange, press the spacebar to see if the light changes back to blue. Your pc power settings might need to be re-adjusted, is the pc going to sleep or hibernating too soon?

I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?

Let me know what happens with the testing above or if you need further instructions to carry out testing.

Thanks, Jim

check the power supply and rem or proccesor

Without looking at the monitor to confirm this, I suspect you have failing capacitors which power the HT circuit, simply, the power needed to light the display, is leaking to earth, capacitors have lost the ability to store the charge necessary to illuminate the screen, which is why it is working erratically.
You need to get this checked out by a TV technician.

the monitor is not getting any video information from your computer .. check the connection at the computer to make sure it is fully plugged in .. make sure the video card (if it has one) is securely in place ... make sure the monitor is actually plugged into the right connector .. you may have a bad video card or a damaged cable to your monitor .. you can plug the monitor into another computer to make sure its ok ..

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

In My Computer, find the icon for Display and configure the energy saving features so that your monitor doesn't sleep as soon.

If you need more help, I will be more than happy to assist.

You have a burned out Backlight Fluorescent Bulb.
