Panasonic TC-P55VT30 SU board?

[djw43]

Hello,
I have a p55vt30 with 7 blinks, I isolated SU/SD/SC closed SC50 and I have fans and an LED on both SC and SS.
I have a short on TPSC1 which is no longer a short with SU out of circuit.

The service manual shows the board for SU is TXNSU1PAUU TNPA5340 but the currently installed card is TXNSU1NVUU TNPA5340AK.
Are both cards compatible, and mine is faulty, or not compatible and I need the other card?
Any help would be much appreciated,
thanks,
dave in NJ

The TNPA5340AK is for PDP- MC140FJ1431 Panasonic 50"GT +VT models
and the TNPA5340 with no prefix is for PDP-MC140FU1431 50"ST models, so I would say your set has the correct board fitted and would need to be replaced with a like for like TNPA5340AK ,but check your panel sticker number for PDP fitted as they may well have fitted both hope this is of help Flocko

yes manual does say that but there may have been a production change/panel variation and so the Su may also have been revised and matched accordingly. Looking at both very litlle difference, removal of a single ceramic cap on the 5340 variant will give you the same board. I would expect it to work, no idea on the long term affects if any.

these are hard to find and expensive. i see a pair from St30 which is the 5340 no suffix $100 USd but why not consider getting yours repaired at $50 which is very cheap as i see over $100 just for repair on ebay.

A lot of people get their Sc boards done there with excellent results.

not sure on their success rate with the buffers but very good reports on most other boards
