I have a similar problem with another LCD monitor (Compaq FP5315). The monitor comes on and then flashes on and off repeatedly, but only when the video cable is attached to the computer. When it is not attached to the computer, the monitor displays the message about no signal or whatever is on the screen and the power stays on indefinitely. When I switched to another computer, it didn't do it for awhile, but after 30-60 minutes, it started flashing on and off repeatedly. Since it works without the video cable attached, I'm assuming it's not the power supply, right? Any thoughts on what it might be?

THere are speakers on the monitor, but I can't hear anything. The volume is on everywhere. There is a green hole in the back of the monitor. Do I need a cord?

Yes you need a stereo jack to connect the monitor through the audio port (green hole) to the green port on your soundcard chip. You can obtain one of these from maplins or Radioshack or similar, which will be cheap. Make sure you tell them you wanta jack with stereo

I have a Compaq FP 5314 that flashes on and off at about every four seconds. It works on XP and shows everything up to the OS coming on. That is all the bios type info, but then starts flashing as above....

The problem is that UBUNTU is setting the screen-resolution to some values that your monitor does not support, e.g., 1920-by-1080, or not setting it to 60Hz.

During boot-up, your monitor uses 800-by-600, so it "initially" works, both with UBUNTU and XP.

Windows "detects" the monitor, and selects "usable" settings.

Attach a new monitor to UBUNTU, and then set the video-resolution to 1024-by-768 and to 60 Hz -- your Compaq should support those settings.

HP Compaq FP5315 15" LCD monitor

It needs the power supply board fixed. I have fixed several like this. It needs 5 or 6 capicitors and a 7.5v zener diode which is really easy to do if you know how to solder. If you dont know how to solder you need to take it to a repair man or buy a new one.
