Last night the monitor worked fine. Came in this morning to check email and the monitor was black. It appeared to be on, but no picture. If I turn it off and then back on, the desktop will flash 'quickly' and then go black. There have been no power surges or storms. Other monitors work fine on same PC. Monitor is only 19 months old. Please help.

Re: Monitor won't work
Try adjusting the video connection on the back of the monitor and kinda wiggle it from side to side to see if there's a loose connection.
One other thing to check (In case it's a newer LCD) is that the video isn't switched to DVI (It should be automatic, but it can't hurt to take note of this)

Hi Michael, it does sound like the monitor then. The most likely cause is bad capacitors in the power supply. Typically a cheap repair but you do have to solder and such. Unless you have to have a very expensive monitor its probably better to just replace it since basic monitors are so cheap these days. Good luck.
Firstly check the power cables nd VGA port is it proper or not nd then if this is proper then ur problem might be in RAM remove the ram and rub it with eraser nd insert it again nd check CMOS battery also ....u will surely get a positive result....
Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.
Just fixed mine. Maybe it's a few years late. Hope you guys still have the display. It's the power supply board. I've just replaced 4 bulge capacitors near one edge of the PS. They are 2x1000uF 10V, 1x470uF 25V & 1x470 10V. I salvaged my parts from an old CRT monitor. Hey you can go green with your repairs too!
I had the same problem with an AOPEN 17' lcd that was left behind at a rental property... I plugged it into my dell dimmension 4400 in place of my old analog. It worked fine the fist night, and got up and when turned it on again it had the famed green blinking power light. I switched back to the analog, and just disappointed I plugged in the AOPEN to another power source, and power came on a steady red light. I plugged it back into the puta and it came on again. I have not turned the monitor off again for fear of the blinks, and has been working great for close to a week now. Hope it helps someone else out there. Richard
