Panasonic Plasma Died, Then Came Back.....

So Wednesday night my T.V. wouldn't come on. Tried the manual button as well. No dice. Unplugged it for a few minutes. Nothing.

Unplugged it for 1/2 hour. Changed batteries in the remote. Nothing.

Tried it multiple times the rest of the evening, remote, manual, you know, HOPING.....

Brought the bedroom t.v. down, started shopping online.

This thing is only a few years old, but hey, shit happens.

Last night had a thing I couldn't get out of, came home around 7:30 and just for kicks hit the manual button.

It came on, worked fine all night and came on again this morning with the remote.

No storms, outages, etc.

Weird......

There is a type of capacitor used in power supply called electrolytic that use a liquid electrolyte They have a limited life. Used incorrectly the life is more limited. Made incorrectly even more limited.

I suspect they ares beginning to wear out, and will only get worse until it will finally quit for good.

Hope you can keep it alive.. Panasonic was the king of plasma.. and plasma, the king of screens..

I bet you could find a local guy that could figure it out if it becomes a persistent problem.

RIP: plasma

Our 50" Viera Plasma is still going strong at 7 1/2 years old. STILL the best picture ever. Bought it at Christmas 2007, when the price just dipped under $2,500. Yeah, really.

And NOT "Made in China." I'm under no delusions - I'm sure plenty of componentry inside is sourced from China - but I consciously stayed away from the Made-in-China products.

Keep shopping, it's only a matter of time. Had the same TV and after 4 years I went through a similar scenario that ended shortly in a new TV. Repair cost estimates were too high to justify the reinvestment. It was a supreme TV while it lasted though and it took a lot of research and shopping to replace it with a reasonably priced unit. When the time comes look closely at the Sony KDL-55W700B, it surpasses the Panasonic Plasma.

You won't catch me buying a Sony TV again. I used to swear by them. Had three at one point. The two old ones still chug along. But the newer HD set burned me. And their reputation is now garbage. They don't make money on TVs and cheaped out. I no longer trust them, and it pains me to write that.

+1

I researched and researched and all the reviews said the quality was the best for the money. But they don't hang on to them for a few years, they get them in, test them, compare them, then send them back.

Mine went wonky after about three years - a control board creates splotchy squares or lines. Sometimes you can't see them, but most of the time you can. Googled it and this is very common for Sony HD TVs

Cheap electronic boards use electrolytic capacitors. When the liquid start to evaporate, the board acts up as stated above. Cheap PCs are made this way and they eventually fail. A good electronics tech could replace them... for ceramic or SMD capacitors... With luck...
