My monitor displays the picture bright and clear for only a few seconds after I turn it on. Then it just goes totally dark. Pressing the buttons and checking the cables didn't help one bit. However, turning it off and then back on agains displays the picture from my monitor crisply for just a few seconds and then goes dark again. Please help! Thank you!
Make sure the 'VGA' lead is plugged in properly. if still dark turn up the brightness on the monitor. if still dark after that, go onto the computer settings and turn up the brightness on the display settings.
Hope this helps!!!

The problem with this monitor is a leaking capacitor on the power supply board. It is the middle one at the top in a row of three. The value is 10V 1000uf. Common problem for these.
Remove 4 screws from back of display. The case can be popped apart with a small flat putty knife at different points along the two seams. Three latches on each side and two at top and bottom. Push and twist at the latch points. There is a metal cover over the two boards. Power supply board to left. Screws and plugs can be romved. Unsolder Capacitor and replace. Radio Shack probably has them. Maybe a couple bucks. Be sure the power has been off for a while. These also have problems with the button board and corrosion at ribbon cable.

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.
