This is not good. Was your tv unplugged or just power button off when you left for vacation. PlasmaTvs are highly susceptible to damage from power surges caused by lighting. Leave unplugged for at least five minutes then plug back in and see if this helps.

It's definitely an overheating problem if your plasma turns off by itself after a while. I would suggest to place a cooling fan near the back of it as a temporary fix.
There could be a power supply issue along with a Ysustainer board but in order to know that for sure, you should use a hair drier and blow hot air to the power supply and see if the TV turns off, if the time that the tv turns off is shorter when blowing hot air to the power supply; then is the power supply issue.
Good Luck.

It related with Power Board(50%) or Y-Main(50%).
But, if you use the power bar with surge protacton, need to check
the power bar's lamp when the TV is turning on & off.

TV turns off by itself & won't turn back on til unplugged, then plugged back in


Well, first your model number is the 42 inch, but I digress...

I had a similar problem with a Viewsonic 27 inch, with the blinking power light on a failed power-up. It turned out that replacing the power transformer was the ticket. However, as I have the 50 inch Panasonic plasma, I know that the transformer is built into the set itself. I'd still suggest that this is what needs replacing though, as this is different from a set being on but having no picture.

Inability to turn on plasma screen


You have a power supply fault or one of the drive boards that drive the plasma screen is loading down the power supply. This power supply may be part of the entire main board. Good Luck
