Game monitor. Green snow/haze issue since getting it, but worked acceptable for few years. Then it got worse, tweaked voltages and works fine again and mounted it on a stand with wheels, but no sound so had to go through the issue of taking it off (2 person job), find that I forgot to hook up soundamplifier PCB and remount it (3 person job).
But now it developed a new issue: it works fine, but after a few minutes, the screen goes black.
I am pretty sure the on-screen volume control does not show either, but the sound still does work (so it does not go into some protection mode).
Questions: when googling "plasma picture goes dark" it keeps mentioning shining with a torch to see if it still has some (dark) picture showing but without the back-light being ON, but plasma's don't have a back-light, correct?
Other likely culprits (again, according to google) are capacitors on the power supplies, but Tom66 mentions in his repairthread that it is not likely a powersupply fault if you still have sound.
He does mention "if you have sound and the TV will respond normally - then it's likely a Y-sustain or Z-sustain fault." But I am not sure what would cause it to function normally for a while before going into 'errormode', so I was hoping this would trigger some great ideas on where to look from you lot before having to take it down again...
Thanks!

whereas before it would do so within 5 minutes.
