Hi all,
Seems we had a bit of a thunderstorm here last night while I was gone and now my monitor is acting freaky. Here's the scenario:
I came home this morning, everything was off. I powered up the system, everything functions normally. All the noises are their happy selves, the monitor lights up, begins displaying the normal series of graphics/text and whatnot..
After about 30 seconds or so, however, the Monitor drops back into "standby" mode.. like it's not getting a video signal.. (screen goes black, power LED switches from green to amber) The computer, however, is still running, making all its happy whirring noises, etc.
I press the power button on the monitor. The monitor powers down. I press the power button again, and the monitor comes back to life, with full display, no distortion, no problems.... for about 4 seconds, then drops back to "standby".
repeated pressings of the power button produce the exact same result. If it let it sit a while turned off it will last 30 seconds or so of full display before dropping to standby.. if I immediately cycle the power after it shuts off, the display will only last for 3-4 seconds.
This *appears* to be a monitor issue... the rest of the tower acts like everything is happy. (I'm actually currently downloading a bunch of stuff on that machine with the quirky monitor hooked up to it right now) Everything was working fine yesterday when I left.
Ok.. relevant system bits... The system is a recent build... I put it together oh, about a month ago. Video card is a nVidia GeForce 6800 model by eVga. Running an AMD Athlon 64 X2 4800+ with 1gb dual channel ddr400, 1 TB archive storage, 74 gig 10krpm SATA "Raptor" system drive, and a beefy 650 watt power supply. Running XP Pro.
I googled for this problem, and I found a bit on a monitor troubleshooting site that suggested the following:
If twice, then the power supply is shutting down as the controller still thinks it is on and you are resetting it. A couple of possibilities here would be low voltage or high voltage regulation error (excessive high voltage is sensed and causes shutdown to prevent dangerous X-ray emission). A partially dried up main filter capacitor could also cause a shutdown but there might be other symptoms like hum bars in the picture just before this happened. Clipping a good capacitor across the suspect (with power off!) would confirm or eliminate this possibility.
Well, I'm not so much of a chiphead that I have a bunch of capacitors lying around or would even know where to clip them to.... but It doesn't seem like a capacitor issue to me.. the voltage regulation error seems closest.
The question is, how might I try and fix it if this is indeed what the problem is, just to rule it out? I don't really have the money for replacing the monitor at this time...
