SERVICE DESCRIPTION - PLEASE READ IN FULL!
Coppell TV Repair offers a REPAIR SERVICE for the power supply shown on the picture and used in Sharp Aquos LC-37D42U LCD TV.
REPAIR SERVICE means that you need to send us your malfunctioning board that we will attempt to service, test and return to you.
Please read below for typical failure symptoms, testing procedures, repair procedure and other important details.
Should you have any questions do not hesitate to contact us prior to submitting the board.
How does it work
First read the failure symptoms and check them against what your TV is doing.
If the listing provides more details or a link to an article with more details on how to test the power supply board or components on the board to make certain it is indeed bad and needs service then follow them - sending a working board to us is a waste of your and our time and your money.
Then you will need to open your TV. Usually a Philips screwdriver and some time and patience is all you need, but remember - do not open or take the board out while the TV is still connected to AC!
The next step is to make sure that your TV has the same board as the one shown on the picture. It is not uncommon for manufacturers to use totally different internals within the same model number and our listings are for particular modules that we are familiar with.
When ready you can click the button saying "Initiate service request" to start the process.
A typical failure symptom for a bad power supply in Sharp Aquos LC-37D42U is a totally dead TV that does not respond to any commands, be it via the control buttons or the remote. Fuses on the power supply board may be blown open or may be still intact - those are practically two different failures resulting in the same symptom - dead TV.
A less popular one would be a TV that attempts to power on, but fails to and falls back into standby mode.
Another also less popular yet always possible failure for this particular board is the TV taking some time or several attempts to power on.
As with any other failure, there is no guarantee that a symptom (other than a blown fuse or other visually damaged component) translates to a necessarily bad board. Failing electrolytic capacitors, for example, can actually perform reasonably well for a while while being visually swollen, i.e. they may be going bad yet not be the source of the current's TV problem.
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.
