Our Panasonic 50" TH 42PX75U


well it sounds like something fried inside the tv. In my experience, this sounds like your y-sustain board went bad. it could be your video board also. considering todays value of the 50" panasonic plasma, it will be cheaper to replace it, unless you are willing to spend around $300 to get it fix at a shop.
good luck

Unfortunately your going to have to have it serviced by an Authorized Panasonic Dealer. Independent shops will not be authorized to order parts without the consent of Panasonic. They are rough to deal with.

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.
