SOURCE: Panasonic Viera TH-42PV7HS Plasma keeps shutting down
Hi to all, My 42" Panasonic plasma have the same problem. It turned itself off and now red light flashes 7 times, than after short pause 7 times again. And so on. Any ideas what is wrong??

Most likely, the problem is a defective Main Processor Board. This is the board with the antenna, RCA and HDMI plugs. You cant repair or replace component parts on this board, so dont even try. You must replace the complete board. The TV says Sylvania, but it is a bloody Funia TV. Several years ago this foreign company bought out broke-azzz Sylvania . They are still carrying the Sylvania name since Sylvania was a popular TV name in the 70s. Every electronic company in the USA is now owned by the Chinese, so call Funai and order the part from them. Dont be surprise if they dont have a clue what the heck you asking for. America and all electronics have gone to the puddles. Do you know why? GREED.

Really? Nobody has a better solution? I have the same problem and the tv's about a year old. That's it!
Crazy!

Hi,
I own the same TV and had the same problem.
It's the #1 plaguing issue with flat panel TV made by Funai corp. Emerson is made by them.
Normally, when this happens, the TV goes into " Protection Mode " because of a failing circuit board.
The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. But, I can't say it's 100% the problem because I can'tactually look at the tv over the internet. I can only make guesses with the symptom. I'm willing to bet you have the same problem like mine. One of six Inverter Transformers when bad on my Power/Backlight Inverter Supply Board. I replaced it and it works fine again.
You have a few choices:
1. You can try leaving the TV unplugged for 30 minutes so the TV can reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual at Tvtechcenter.com; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $6. And most cases the new part cost less than $15. The service manual at the site is under LC320EM82S.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

Hi.
This sounds like you are experiencing the same thing as thousands of other tv owners right now.
Your tv is suffering from " capacitor flu".
The capacitors that control voltage regulation, convergence, or the ones on the main board have failed.
This is not due to anything that you have done, it is because about 15 years ago, some companies chose to put profit ahead of quality.
There were about 20 electronic component manufacturers in the mid-1990's that mass manufactured capacitors, and they were done so with the wrong formula for capacitance gel. They used a formula which was later determined to be harmful to the capacitors, but instead of pulling those off of the market, they ignored the massive failures and left then out there on the market anyways.
All together, the companies made a combined 50,000,000 capacitors that were junk, and instead of lasting the 25-30 year design like they were supposed to, some of them are only lasting a few months to a few years, at best.
Now, that isn't to say that this means that your tv should be tossed in the trash, but if you take it to get it repaired at places like BestBuy, Fry's, or Staple's...you will want to get an estimate of repair costs before actually having it done.
The reason for this is because to get the proper capacitors put in your tv is a time consuming, and expensive repair.
You may find that the cost of repair is more expensive than the cost of replacing the tv, or you may find that it reasonably priced to get the repair.
That is why I recommend getting an estimate first.
This way, you will know ahead of time which way is the most economically feasible venture for you.
I hope this helps you understand what is going on with your tv, and that it gives you some insight as to how to remedy the situation.
Good luck to you, and have a good day.
