Vizio Plasma (VP422) Random shutoffs.

[sattech200]

Evening everyone.

Have a Vizio VP422 Plasma that will randomly shutoff to standby randomly agter being on for 2-15mins. When it does this i just press power button and it will turn back on for another 2-15mins. Dosnt seem to matter what input its on although it seems the longer its been powered on the quicker it'll shutdown but thats not set in stone.

I have cleaned and reset all connectors plus performend a thourough visual inspection and see nothng.

It does have a couple of verticle lines which i suspect is from a failing screen but it would work perfect for the kids.

Ive been trying to research this problem but seem to be coming up empty handed.

Any help or sugestions would be GREATLY apreaciated.

Will upload pics of boards shortly.

Thank you

Id suspect solder joints on the Psu start there.

ok, I cleaned up a bunch of them but still having the issue. After working with it more I've found that it is a much more consistent shutdown right at about one minute. This sounds to me like a protection shutdown but I'm not finding any information about that.
