Repair service for Samsung Y-Main board BN96-04574A used in a number of 50'' plasma TVs


Coppell TV Repair LLC offers a REPAIR SERVICE for your Samsung Y-Main board BN96-04574A as shown on the picture and is used in a number of 50'' plasma TVs.

REPAIR SERVICE means that you have to send in your malfunctioning board in order to get it serviced and returned to you.

The most common cause for failure of Y-Main LJ92-01399A is a failure of one of the two buffer boards at its output. Because damaged buffer board can kill the sustain and an already killed sustain could damage a working buffer board we ask that you send us all three boards.

Processing time

Typical processing time for the repair is within two business days; if we have any probems that require more time (be it overload or technical problems) we will contact you with an update and request for more time.

We have a fairly high success ratio, but we still do not guarantee success; if we can't get the board to work, though, you will not need to pay.


Presently we do not charge in advance for repair services.

Instead, once the board(s) are received, tested, found to be defective, serviced and tested again to success we send a payment request to the customer.

If something along the process - such as unexpected difficulty or finding a board to be functional - arises we contact the customer via email and/or phone and disscuss options.

Minimal charge / diagnostic fee

If a board arrives and is determined to be functional we charge up to $25 for diagnostic fee.

For explanation of why do we do that please read this article.

Board requirements

We ask that the board arrives here in good physical condition and without traces of tampering. If someone (other than us, that is) has already attempted to service the board then please contact us with a description/pictures and do not directly place an order. We reserve the right to refuse service to boards that have signs of repair attempts.

If you have any questions do not hesitate to ask.
