SERVICE DESCRIPTION - PLEASE READ IN FULL!

Coppell TV Repair offers a REPAIR SERVICE for the YSUS board shown on the picture and used in LG P50HDTV10A and other 50'' plasma TVs.

REPAIR SERVICE means you have to send us your malfunctioning board that we will attempt to service, test and return back to you.

Failure symptoms

There are several failure symptoms pointing out to that board. Few of them are unique ,though, so pay close attention to avoid creating false expectations in a self-diagnosing experiment:

  • Flashing image on the display of your TV - that's a typical symptom for a failed YSUS board and while not 100% guaranteed if you have it there is next best to 100% chance that the YSUS is bad
  • TV comes up (possibly with sound), but the display remains dark . This symptom is usually preceeded by a reasonably loud pop of death (POD) or, sometimes, a series of pops.

    It is easy to lose the sound when you press buttons randomly trying to make the TV show the lost picture and switching the input or the channel, so loss of sound is not a neccessarily any significant indication here.
    This symptom may also be caused by a failed ZSUS or other board (very unlikely power supply board though).
    One extra thing you can check is the temperature on the YSUS heat sinks after having the TV run for 5-10 minutes with our without sound (better with, takes less time). Both sustain boards should be notably warm to the touch and if one isn't then it increases the odds for this to be the bad board.
  • TV does not want to come up at all - clicks on and then quickly clicks back off. If you have a multimeter, you'll be looking for a shortage in the Vs pins to ground on both the YSUS and ZSUS boards, which are connected to each other with a cable running above the power supply board. Disconnect them before testing for short on Vs to GND pins (GND is also all the metal on the chassis including the back of the plasma panel).

    If you do not have multimeter you can disconnect ZSUS from YSUS and try to power on the TV again; if it comes on and stays on this time then the bad board is the ZSUS board.
    If it still does the same then you've got bad YSUS and/or bad power supply board. Or (unfortunately), it could be something else too, but if the symptom was preceeded by a pop of death then it's likely the YSUS.

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.

Payment

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.
