I hope its still under warantee, I just bought a 50" and they told me the extended warrantee was wise as it would cost at least $800 if any thing went wrong, thats about 3/4 what it cost new.

No it's not under warranty which ticks me off when you pay so much money for a tv and under 2 yrs old it stops working. Samsung has the worst customer service I have ever dealt with. Oh ya, I just fixed my bedroom tv and it was a Samsung too only a 1 1/2 old.

Hit the TV hard on the side and if the TV works then look for a cold solder joint around the vertical section. Sometimes these tvs make so much heat it softens the solder joints and by tapping it for a loose connection you can isolate this type of problem. Not that I own a plasma tv but this is how I rule out a loose connection.

How old? Plasma TV screens have a finite, screen life. They degrade from the first day you turn them on. LCD are better and LEDs are the new "supposed", untested long run, standard. Digital modules are just that. In an LCD, pretty easy to replace but very costly. Like 1/2 -2/3s the cost of a new one. I was at a shop and saw a Plasma that was opened up and it was complex. I am an Avioncs tech on Helicopters by trade and I wouldn't have messed with it without a detailed service manual and a class in Japanese. Good luckCentury Hawk Sport, OS .32, Futaba 7C, GY-601 9251

It's been sitting for a year because I bought a new TV instead of waiting for it to be fixed, so it's around 3 yrs old, it retailed for $4,200 I paid something like $2,000 for it.

Plasma has the best picture. It has a 600hz true refresh rate as opposed to the LCD's fake 240hz. LCD can only do 120hz so they interpolate the frames to double it.

The reason LCD's are so popular is in the stores under bright florescent lights, the LCD has a brighter picture. Nobody has that lighting in their living room. People see this brightness and equate it to being an overall better picture. Not so.

If you have a bright room, LCD is better.

This LED TV kick is a false statement also. People think the actual pixels are LED lights. NOT TRUE... It's just the backlighting. LCD's have to be backlit. Plasma does not. All LED means is instead of using fluorescent backlighting they are now starting to use LED backlights.

LED LCD does use less energy and does not generate as much heat. That is a big plus.

But for the discriminate home theater aficionado Plasma cannot be beat. Go to the high end retailers and talk. Plasma is more like a CRT screen... warmer, smoother and easier to watch. LCD is harsh.

Concerning life, plasmas are rated for 7-10 years. Some will last much longer and some may quit sooner. I don't see any reason for an extended warranty though. You are betting it's gonna break. Your chances are more likely that it won't and your first repair might be the same or cheaper than the cost of the warranty.

Off the soapbox....

I have a 65" Panasonic plasma.
My warranty is 1 year on TV and 2 years on the plasma display. Extended warranty is $600 for an extra year and $800 for 2 extra years.

The SD card reader had some problem and would not hold the card in. I had it fixed under warranty. Here's what it looks like "unplugged". We had it off the wall fixed and rehung in about an hour.

I'd still try smacking it pretty good.

What can it hurt at this point?

I would say your TV is screwed. I had a LG 42" plasma and it got the vertical line through the left side and it got bigger and bigger. The plasma TV was less then 2 years old when it happened. I also bought a 60 inch LG plasma and in the fist 2 months the circuit board that turned the TV on and off died. They didn't have the part in stock because it was such a brand new product we had to wait 3 months to get the part from the factory. Then the repair people took another month to put it in because they didn't have the wiring diagram and had to wait for LG to send it out to them. BTW, we paid a little over $10,000.00 for the TV and they wouldn't give us a new one. I eventually sold it before we moved here and the person that bought it had the power supply go up in smoke. They fixed it under warranty because it was under 2 years old. I will never buy another LG TV again. We still have plasma TV's, but one is a 54" Panasonic and the other is a 42" Samsung.

Take Care,
Cheers, Patrick

Panasonic is one, if not the most sought after in large plasma. They are a top name with some of the best performance specs out there for significantly less price than the ridiculous Pioneer and Sony flagships that go for 6000-8000 dollars. Actually my 65" Pany listed originally for $5999. I bought a display unit for $3500. You can get new ones now for $4000 or less.

Always good to buy last years model, NIB preferably.

Look fixable.

Probably little ribbon cables on the side got loose. (ABUS Up and Abus Down/low) (Y-sus and X-sus) Remove every single ones clean and re-seat. Use an eraser to clean them carefully. Or it could be the board that those ribbons cables plug into.

Plasma TV are easy to DIY repair, unless the panel it self has gone bad. Everything in side in modular and you can fix by just replacing broken boards. Usually you don't need to re-calibrate like the old CRT and not as dangerous working the back of the tube.

You can get Service Manual for Plasmas pretty easy if you poke around hard enough. FixYa.com have very good knowledgeable people on there they will help you and you pay them what you think worth for answer. For $10 somebody may have good answer for you.

I was given a broken Hitachi 50" 1080P TV in fix it/Keep it deal. $200 Later it was fixed. Just need to replace a board, took me awhile to find which one was bad though.

I talked to a Tv professional and he has never heard of what mine is doing. I tried unplugging all the boards and blowing the dust off, it didn't work. Then I tried the old slap the crap out it with no luck.

I am thinking it might be something stupid seeing I am having a hard time finding info on what mine is doing.

this may be a stupid question, along the lines of "did you put gas in it", have you tried the TV with a different source? I mean a source on a completely different input?Stupidity can be cured. Ignorance is for life!
