Hi.
Anyone`s got to a clue on the issue? I have the same problem with a fujitsu-siemens monitor (scaleoview c19-6). It goes on for 2 or 3 secs, then goes black, although the power led is on (green). If I turn it off then on again, it goes on for another 2-3 secs, then black...
It behaved the same with 3 different computers (I was looking for freq incompatibility between video board and monitor).
Sure it looks like something related to capacitors, but what am I looking for? Signal circuitry or backlight?
Thanks fellows!

Hi. I have the same problem with Acer AL1511 monitor on AcerPower F1 PC. It initially appears to start up fine then goes blank with a "No Signal" message display. I am able to prevent this from happening by constantly jiggling the mouse (small movements back and forth) during startup until the logon is displayed. It's a pain and I'd love to know how to FIX it.
