SERVICE DESCRIPTION - PLEASE READ IN FULL!
CoppellTVRepair offers a REPAIR SERVICE for your 42'' LG Y-sustain board as shown on the picture.
REPAIR SERVICE means that you have to send in your malfunctioning board for us to repair and return back to you. Sale of a serviced board or a trade-in service may also be available, depending on current availability.
The following are popular failure symptoms of a failed EBR31872801 sustain board:
1) (solid) If you find an open fuse on the board (infinite resistance) that is a certain indication that the board has failed. No use trying to replace the fuse alone, it won't help - the IPM and possibly other components need to be replaced.
2) (solid) If the TV starts with a flashing image then it is fairly certain that this board needs servicing. It is not 100% certain, but at least statistically it is as close to there as it gets. The effect a strobing about once every second. Sometimes you can see an image and sometimes you can't.
3) (solid) If the TV refuses to start with the board connected to power, but starts and stays on when you disconncet that board from power then you know for sure it is bad.
4) (medium) If the TV starts, but has dark screen and the heat sink on this board is NOT warm after 5-10 minutes of the TV staying on (ideally with sound so you know it's trying to render an image as opposed to just being on an input without signal and showing a black image) there is a good chance this board has failed.
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.
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.
