Blue Flash - video signal lost

#1

My system monitor flashe blue and sometimes returns to normal, but usually loses the video signal and goes into powersave mode (no signal message displays). Turning the monitor off for a few seconds, then back on restores the signal. In 60 sec or less, the problem repeats itself. I also noticed glitches in the output (image skews horizontaly for an instant) just prior.

The issue does not seem to affect the computer yet.

I am thinking the video card is overheating (after shutdown the pcb opposite the GPU (Nvidia Ti4400) was hot to touch.

I removed the AGP card, and inspected it, but have not attempted to remove the heatsink/fan. There does not appear to be any damage (that is visually detactable).

Should I attempt to remove/replace the video card heatsink, or just replace the agp card? Could this be he mobo chipset overheating, or possibly the CPU?

Any advice/suggestions welcome! Sorry for the long incoherent post, but am in a rush (borrowing sister’s laptop).

Have you tried a another monitor? Sounds like it’s dying.

Good thought… I will give that a shot…

but if it is my monitor, I will miss my beloved Sony G400 :frowning:

UPDATE: Dizzy, you were 100% correct! Sound the trumpets! A moment of silence for my dearly departed Sony CPD-G400. :sad:

…and only does not make CRTs anymore :a :a :a
