Repair service for Panasonic TC-P50GT30 plasma TV failed SC board TNPA5335AJ or TNPA5335BJ - 7 blinks LED failure code or other


We offer a repair service for failed Panasonic SC board TNPA5335BK / TNPA5335 used in Panasonic TC-P50GT30 plasma TV.
$84.95

Coppell TV Repair LLC offers REPAIR SERVICE for Panasonic SC board TNPA5335BK based on  TNPA533 PCB as  shown on the pictures.

TNPA5335BK is used in Panasonic TC-P55VT30, Panasonic TC-P55GT30, Panasonic TC-P55GT31 ,Panasonic TC-P50GT30 and possibly other plasma TV models.

The board's product identification TNPA5335BK can be found on the white label on lower right of the board while TNPA5335 can be seen prited in the middle of the PCB close to the buffer board connectors.

Note we also offer repair services and/or exchange service for SU and SD buffer boards TNPA5340 and TNPA5341 (see failure symptoms section below).

We recommend that you send the buffer boards along with the SC board. If you do we will test each of them in a live set and charge you $10 per buffer board test unless it has to be reparied, in which case we'd charge the standard buffer board repair fee as advertised, adjusted for combined return shipping.


HOW DOES IT WORK

To have us examine and possibly repair your board(s) you need to send them or bring them to us.

Start the repair service request through the "Initiate service request" button on the page. Repeat customers are advised to log-in and new customers will have to fill-in a short form with contact information needed for communication and invoicing.

An email with shipping instructions is automatically sent once you submit the form to the email address you provide; it is also shown on your screen.

Following the instructions you package your board(s) and attach the first page of the shipping instructions so that we make a link between the boards and the service request when we receive your package.

You then send the board as shown on the picture to us. You pay for the shipping to a carrier of your choice and nothing to us at this point.

Presently we do not charge in advance, but only after inspecting and possibly servicing the board(s) we receive.

The price shown is for evaluation, repair, test and return within USA of the boards listed in the title or explicitly named in the listing, provided they meet our requirements upon arrival (see related section).

Boards returned abroad tend to have higher shipping cost that will increase total cost of service beyond the amount shown.

Once we receive the package and open it we inspect the board(s) sent.

If the board(s) do not meet our criteria we communicate the problem with you and offer options, the first of them being returning the board(s) back for sole cost of return S&H. Other options may include surcharge for board restoration, board replacement, change of pricing or warranty terms etc.
We may not give any options and simply reject to service a board that was damaged beyond repair (see example here).

If the board(s) pass our criteria we conduct test to determine functionality.

If test passes OK and board(s) appear in working order we communicate that and offer options, among which returning the board(s) without change; we invoice a testing fee and return S&H charge.

We test all boards that are being sent and for every board we test we assess testing fee as described.

If board(s) come in assemblies that require additional dismantling on our end (i.e. with more than what is shown on the pictures) we reserve the right to charge up to $10 for dismantling and re-assembling what was sent plus eventually additional shipping costs if resulting assembly requires larger box and/or is heavier than the regular board as shown.

Boards that test out bad are analyzed and we attempt to repair them.

If we succeed we send a payment request for the amount specified in the listing.

If we fail to repair the board(s) we send you an email with details and usually only request that you pay for the return shipping and nothing else.

Please make sure your TV has the same board before proceeding with this service or contact us if yours is different to see if we offer repair service for it.

FAILURE SYMPTOMS

SC sustain TNPA5335BK fails sometimes when buffer boards fail and sometimes it fails on its own.

When the SC board fails it may or may not take down a buffer board (very rarely both) and the ther way around - when a buffer board fails it may or may not take down the SC board.

We have seen either and all boards fail at the same time and have not been able to establish a firm correlation.

When either board is bad among SC, SU and SD the result will be the same - 7 blinks. Some report also 6 or 10 or 14 blinks, but we can not confirm that at time of creation of this listing.

A defective SC board TNPA5335BK is usually easily identified by testing for shortage on any of the following components: Q621 and parallels, Q401 and parallels, Q421 and parallels Q661 and parallels.
If either of those measures short between any two legs the board has failed.

A defective top or bottom buffer is usually tested between floating ground (metal screws) and output pins for the plasma panel.

SERVICE TIME

All packages we receive are placed in a FIFO processing queue.

It takes 2-5 business days for a package to make its way from the back to the front of the queue.

Once picked up for processing, we make money if we manage to fix the board(s) inside for between 30 and 60 minutes.

Of coruse that isn't always possible, not to mention sometimes there is more than one board in a package.

Add to it that we can't know how many packages we will receive at any given day, how many boards will each contain and how bad the damage on them could be.

Please do not call us a mere few days after you sent your package to inquiry about the status of your service...we just do not have the resources to be giving the same answer to everyone and it only slows us down!

Look at the tracking number, see when it was delivered, give it at leat 2-3 business days (preferably four) and if you have not heard anything from us then contact us saying the package was delivered on this and that date and we'll go look for it.

It's in everyone's interest that we work as fast as possible and interrupting technicians (who answer the phones) to make them go search for package in the queue only to tell you it's there doesn't help anyone.

WARRANTY CONDITIONS

Unless otherwise explicitly stated elsewhere in the listing the boards we sell come with a standard 90 days warranty.

Customer is responsible for return shipping and Coppell TV Repair LLC is responsible for shipping back to customer. Returned boards subject to exchange, service or refund, subject to availability and agreement by Coppell TV Repair LLC and customer.

Returned boards must carry the Coppell TV Repair LLC identification stamp or label and must not have been damaged, modified or otherwise tampered with in order for warranty coverage to remain in force.

Boards returned with request for refund / order cancellation will be subject to restocking fee covering forward shipping cost, transaction cost and $10 fee for the board testing needed prior to slating it for sale again.

REQUIREMENTS FOR THE BOARD(S) SENT IN FOR SERVICE

The board(s) we receive must be physically intact and must have not been tampered with or serviced before.

The advertised flat rate for repair service is only valid when the above conditions are met.

Exceptions are possible and often applied for minor repair attempts, but we reserve the sole right to judge if and when we would consider a repair minor.

If we receive board(s) that fails the above conditions we will contact the sender and usually offer two options: 1) returning the board(s) for the sole cost of the return shipping; or 2) continuing the repair service at a higher cost in case of success.

It is also possible, depending on the condition of the board, to eliminate the second possibility and just flat our reject having to service the board.

Subject to situation and availability we may also recommend replacement of the board, again at the higher than advertised price for repair.

In all cases you will have the option to receive your own board(s) back for the sole cost of the return shipping.
