Introduction

I could not find a replacement part in stock anywhere online as it is no longer manufactured. However, it is possible to send your broken board away by mail to have it fixed. Mine stopped working after a thunderstorm apparently caused an electrical surge.

If you choose to do this keep in mind that you will be unable to use your TV while waiting for the board to come back. The fee for sending the board away for repair was about $95 and took about two weeks.

What you need

Step 1

              Remove TV From Stand

Remove the TV from the stand and place glass down on a flat, soft, and clean surface where you will have easy access to all four sides of it.

Step 2

              Check/Confirm Model Number

The model number of your TV is located on the back panel.
This guide was written specifically for a TC-P55VT50 (55 Inch Panasonic Viera Plasma TV) model year 2012.
Other Panasonic Viera’s may be similar - but I make no promises!

              Prepare TV for Surgery

Remove the power cord and place the TV screen down on a soft surface, like a blanket.

Step 4

              Remove back of TV

The back of the TV is held in place by many small Phillips head screws. Most of these are around the edges but there are also some by the power input and media inputs. Make sure to keep these screws in a safe place!

Step 5

              View of the TV with back cover removed

With the back cover removed we can see that everything is spread out. Be careful of the copper coils in the middle as these are part of the TV’s power supply.
The board we want to replace is located in the lower right - see red box in image.

Step 6

              Disconnect cables and ribbons from board

To remove the board, we first need to remove all the various connectors to it. Note that ribbon cables are a little tricky with the connector folding down onto the ribbon.

              Remove first mounting bracket

Remove the first mounting bracket - note that it overlays the bottom bracket, the order that these are removed is important.

              Remove the board!

Note that there is a small amount of soft silicone under the board so you may have to wiggle it lose.

Step 10

              Mission accomplished - extra credit - clean the fans

Now that you have liberated the HDMI input board you can send it away for repairs.
While you have the cover off your TV - consider cleaning the two fans as mine were dusty and starting to make some noise.

How did you know that board was the faulty part? Thanks

Daniel Moore - Aug 20, 2017

The built in apps still worked, as did the component input. Only the HDMI inputs did not work. Plus, some googling revealed it is sensitive to power surges and we had a storm before it stopped working.

Out of curiosity, where did you mail it for repair?

Daniel Moore - Aug 28, 2017

PTS Electronics, Inc.

No issues, mailed the board in, waited, got it back and it worked. Never had to email or call anyone. It was $95 at the time.
