Question about Panasonic TH-50PC77U 50 in. Plasma TV

Open Question

How do I diagnose problems with Plasma TV. Does anyone know of a company that would diagnose and repair Plasma TV circuit boards via mail?

My Panasonic TH-50PC77U stopped working, no picture or sound, but powers on, I can access the Menu and make changes. 2 weeks ago the picture and sound slowly started to get distorted, while flipping channels sometimes the screen from previous channel would freeze on the next channel. Now, I have no picture or sound. I tried reset from the menu options, but didn't work. I am looking for a company, where I could take out the circuit boards and ship it to them for diagnosis and repairs. Would appreciate any help in diagnosing which circuit board is defective and causing the problem.

Yes the control board would definitely be the offender here. But a word of caution. Oftenj when this board goes 2 other boards are also compromised and not always obvious at the time people think they can just swap the board out.
It went for a reason, not just old age. So it is better and cheaper in the long run to get a professional to check it out.

Also from a safety aspect, this is the High Tension area of the TV. Also be aware that radiation of the X type is in abundance at the rear of the tube. The TV must be grounded when opening ( but my advice is dont!) Let the professional do it

Repair power board


How do you know that it's the problem? Do you hear the relays come on? Does your tv blink? How many blinks? That is a vital part in diagnosing a panasonic tv.

My panasonic viera 50 inch plasma wont turn on. When i turn it on a red light comes on and nothing else


I had the same problem with a Panasonic Viera Plasma TC-P50S3 with 14 flashes. I used an ohm meter tocheckcontinuity of the boards inside, starting with the power board (power to TV off). Check YouTube for videos on how to do this. The SC card showed a fault (It was reading close to zero ohms on both pins. I could find no one who supplied SC boards and could only find repair kits. Repairing a circuit board is outside of my ability, time and tools. I found a place online to send the SC board in for repairs. $65 plus shipping. I was getting $350 "ballpark" quotes from Panasonic authorized TV repair shops. If none of this works for you, there are TV salvage companies who will pay you some cash and pick up TV from you. You can also sell it on craigslist for salvage parts or part it out separately. The various boards seem to cost around $100 each and you likely have four or five in your TV. At least for my TV, the parts don't seem to be out there, so there is a demand for the salvageable parts.

Something short circuit with its circuit board. you must have through knowledge in electronics, and work experience to do repair work to this Plasma TV. As you know, plasma TVs are the latest technology devices, and a mere knowledge in electronics will not help. It will be best to get this set repaired by any experienced service technician or by the authorized service center for Zenith at your town. [Short circuit protection circuit energized, and latched the relay, not to supply voltage to damaged circuit board is the problem] The click sound you heard was the latch sound of the protection relay.

I have a dell 50' plasma tv when turned on does nothing. no audio or screen display. dell tells me $1500 for shipping or s.o.l. they know there is a problem but hope custs dont complain. help


If the TV is under warranty, give them hell. Shouldn't pay more than the TV is worth for shipping, any less a dime.
If not under warranty, best to have a TV tech to come to your home to diagnose the problem. Depending on where you live, independent TV repair shop will charge about $100 for the diagnoses service. Common things that go bad for plasma TVs is the Power Supply Board or the Y buffer/main parts. Basically, cheaper to have someone come to you.

I have the same problem with my LG TV . Mine is also a 42"


Most likely the TV has a power supply related problem. The most common thing to go out 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't actually look at the tv over the internet.

If you have some electronic experience, if you can find and purchase a Service Manual over the internet; 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 $20. And most cases the new part cost less than $15.

I hope I shed some light on the subject for you.

Listen folks, these tv.s do not operate as the old tv. The tv breaks down, you simply change the board you know that has the problem only. You can solve the problem yourself if you want, but you have to know how to diagnose a problem in the new tv. First, you have a power supply board, main digital board, inverter board, and converter board. In your case you need to change the main input digital board. You can e-mail me at Stevebuy31@hotmail.com
