Possible issues are backlight failure or defective LCD panel.

If you have been using this monitor for some time, it's possible that the CCFL backlight is starting to wear out. That would mean it is time to buy a new units. Backlights are not a usual item that is serviced by replacement. Otherwise, there could be an issue with the backlight circuitry or there may even be a failure of the main board. Advise taking it in for service to get a more accurate diagnosis.

The LCD panel is most likely defective. Time to replace the unit.

The volume up button may be jammed in the down position. Try pressing the button to free it. Otherwise it could be a shorted volume up button.

The VA2037a-LED model does not have audio. It's the VA2037m-LED model that has audio.

Plug in the audio cable from the computer to the audio input port. Then adjust the volume to the desired levels.

Disconnect it from computer and power. wait 15 minutes and plug only the power back in, press the power on button. The monitor may display a message that there is no signal or something like that. If that happens the problem is either the cable or the computer. If you get no message then look for the menu button and press it to see if any thing appears. If not find the manual on line and read it. Many times monitors get over-driven by computers to the point that they can't display OR they self destruct. OR Another way is to just unplug everything computer and monitor for 15 minutes. Plug in monitor first then plug in computer and press the power button, the display should display the booting information if the cable is good and the monitor is good.

Something inside is going bad; most likely the switch itself.

Separate wiring so there is no cross-talk of signals. If speakers fail, buy new set <$20.00 (walmart), and hook up, then you have great sound.

Hi Walt, You probably don't want to hear this but your monitor is old. If a monitor has lasted 5 years with reasonable use, then it has performed well. When I was researching your product I saw it was offered for sale in 2006. When electronics start to have issues like this, it's a sign to buy a replacement.

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor. 2. Verify the monitor cable is firmly connected to the computer and the monitor. 3. Verify that you have turned the monitor power switch on. 4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works). 5. If the power light on the monitor is not on, try a different power cord. 6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced. 7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

While booting the PC changes resolution several times. It could be that by the monitor finally locks onto the signal, the PC changes it again so it tries to lock on again. Question is, does the video stay on when the PC finally stabilizes onto the desktop screen?

Getting the parts needed and repairing this monitor would probably not be cost effective. If nothing happens when you try to turn it on (i.e. no lights or LEDs come on) then it probably is the power suppley circuitry that is failing. If you are technically capable, you could remove the covers and look for a blown capacitor (the loud bang sounds like a capacitor).
