IGT G23 MLD Back Monitor Intermittent Issue

[froggy2066]

The back monitor on my G23 works for about 15-30 minutes then the graphics begin to jitter. After about another 15 minutes or so the screen will turn all white and I have to unplug the vga and plug it back in to get it working again. All 4 fans are on and spinning. Is the back monitor going bad?

Too bad you didn't detail whether you pulled the VGA off of the brainbox or off of the monitor header plug.
It sounds like the graphics card on the MPU is heating up...check the fans on, around, and in the brainbox.
It would be the vertical upright circuit board/card that your video cables plug into on the front of the brainbox.

It could also be a cold solder joint on a header connector.
Re-flowing the solder on the pins may help.

Sorry i didn't specify in my original post, I have to unplug and replug the VGA that goes between the 2 VGA ports on the back of the monitor.
The front display works 100% of the time with zero issues, its just the back monitor giving me problems

ok...but why would the black connector video plug coming from the brainbox be so loose?

That’s not my machine it’s a picture from the internet I used to reference the VGA cord I was talking about. The black cable is fully seated and screwed on my machine and I’ve already reseated that cord as well

Try another monitor to see if the white out happens?
Plug the black connector from the internet picture you used in the last Reply, into any old, known-good desktop computer monitor.
If the whiteout/jitter happens after 15-30 minutes, then you KNOW the problem lies with the graphics card heating up, and not the monitor.
