Coppell TV Repair LLC offers functional board TNPA5341 used in a number Panasonic plasma TVs.

Coppell TV Repair LLC offers fully functional SU board TNPA5341 as shown on the picture.

It is used in Panasonic TC-P55GT30, Panasonic TC-P55ST30 and possibly others.

The board is a used one.

It may have been serviced by us if it was found failed, but most of the these boards we see have not failed. In fact, it would be a good idea to make sure your board is indeed bad before you order one!

In either case it would have been tested in a live set and is guaranteed to be functional.

Upon receiving and installing it we kindkly ask that you return your old defective dud back to us. We would provide return shipping label if you agree to send the old board.


A failed Panasonic TXNSU1PAUU / TNPA5340 SU board or TXNSD1PAUU / TNPA5341 SD board will cause failure to power on the TV and 7 blinks at the front power LED indicator.

Each buffer board can and should be tested for shortage as shown on the below videos.

More impotantly, as the video shows, a failure in either buffer board (SU or SD) is often times accompanid with failure in the SC sustain board.

We offer a repair service for the SC board TNPA5351 as well and we STRONGLY recommend that you test and send that board as well; you can initiate the repairs service for either of the boards and send them all along (SC, SU and SD).
