LCD Monitor Problem Diagnosis
I have 17 LCD Monitor that I purchased the Spring of 2005. It started acting up around 6 months ago. For periods of time (not always) it would appear to briefly lose the signal every few seconds. I would also typically get a brief signal loss message when I would lose the signal.

The PC recently had a motherboard failure so I upgraded to a mostly new system (Only re-used Monitor, Keyboard, Mouse, DVD-RW Drive, Floppy Drive, Speakers).

Last night I turned on the Newly built PC (Phenom Quad Core) with this monitor attached. During the approximate 10 minutes that I had the PC on the LCD monitor malfunctioned in the same manner as with the old PC and the problem was continuous. Tonight I plan to swap the "problem" monitor with another LCD Monitor.

1. From your experience, what are the odds that it is a monitor cable problem rather than defective monitor? I do not have a spare monitor cable.

2. Are there any other "tests" that I could perform to confirm that the monitor is defective?

I have already selected, but have not ordered, a replacement LCD monitor. I want to feel confident that the monitor is defective before ordering the new one.

Thank You in Advance.

In my experience so far its never been the cable. Its been the monitor a couple of times and the graphics card taking a dump a couple of times. As long as the cable never gets pinched a lot or is subject to constant movement or pulling there isn't anything that can fail there.
