Question about Panasonic Viera TH-50PX80U Plasma TV

1 Answer

I have a Panasonic TC-P50V10 and I got the "won't turn on three blinking lights" I got my hands on a service manual and diagnosed the problem as a faulty A Board: TXN/A1DRUUS. Of course no place on the internet stocks it. Panasonic can get me the part for $440.00 (I can just buy a new TV). So I am trying to decided what is wrong with the board maybe I could fix it. None of the capacitors look blown (or anything for that matter). TV went out after we lost power. Any help Would be AWESOME. Thanks in advance for YOUR time. Charles

Actually, troubleshooting and repairing a Plasma display is a very skilled work. Everybody thinks that, it is nothing difficult case, and can do it easily for everyone, like a dress change. These devices have the most updated technology, and all are working with software support. Even an experienced service technician might take some time to locate the exact faulty component. I'm doing the service work, since 40 long years, still doing the same.
Keep in mind, that, to the device before you, and which you're trying to repair, you should have enough practical experience in servicing it.
It is not a toy. Never make it irreparable. Do you think that a plasma TV, works only with some capacitors on its circuit. Don't you see any other components on its circuit board? Each and every component you see in the circuit board, have its own duty, when the set is switched on. If any one of them is faulty, the picture will show its consequences.
Mr: Charles, this is not an easy work to do for you. Contact any service technician, or contact the authorized service centre for Panasonic.
If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

SOURCE: no picture and power light blinks 7 times on my viera tc-p50st30 plasma tv when it is turned on

That can be caused by either the SC or SD board. Contact the people at www.tvrepairworld.com they can assist with proper diagnosis and they also should have the replacement board

My panasonic tc-p50g15 red light blinks three times wont turn on


The 3-blink power light code on this model indicates a fault in the A-board (the one with all the input jacks) on the 3.3v line, according to the service manual for this model. The easy solution would be to replace that entire board (Panasonic part# TXN/A1FFUUS), however its somewhat difficult to find in stock now and when you do, it tends to be expensive. I have the same T.V. with the same problem. Currently, I am trying to isolate the exact board component responsible for the failure, but as of yet no luck on that. If I do find it, I'll post back with more information on what the problem was with mine. Meantime hopefully this at least helps you and others with the same issue to narrow the problem down a bit. :)
