Plasma TV turns off by itself-won't sty on for

7 times blink is a Y sustain PCB defect. Facing TV from the back... its the board on left attached to the upper and lower buffers

Tv have problems with it 2 backlight buffer boards,like to help the tv Plasma screen panel to stay consistantly lite with same brightness.Take ur tv back where u bough it.Trade it in for another tv this tv have deffective and dying backlight buffer boards.

Flashing error codes could be the Direct tv box itself.Because tvs have problems within itself don't flashes error codes on the tv screen,the problems,just show up.Tries tv and Direct tv satellite box unplug,replug it back like about an hour later.By letting the tv resetting itself back to the factory setting and the Direct tv box updates it softwares data's.The problems should be solved,if have the same problems,first call Direct tv for a replacement box,see how it work out.Than turn ur attention to the tv.

Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

The TV needs a new Power Supply inside.

It could possibly be something wrong with the computer inside the tv. And you can either pay to get it repaired or buy a new one unfortunately. I would try to contact the makers of the tv though first and make sure to have the model number and all of that ready.

my less than 2 yrs. old hardly used Samsung plasma is turning off automatically for no reason within 10m minutes of watching. What could be the problem??????????

Here's the number to HP case management 877-917-4380 ext.79, try this number and be firm that they need to fix this, I just had an HP plasma that was 3 yrs old replaced for free, no charge. Good luck

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.
