SERVICE DESCRIPTION - PLEASE READ IN FULL!
Coppell TV Repair LLC offers REPAIR SERVICE for power supply board Samsung BN44-00162A used in a number of 50'' plasma TVs such as Samsung HP-T5044, Samsung HP-T5054 and Samsung HP-T5064.
REPAIR SERVICE means that you have to send us your malfunctioning board which we will attempt to repair, test and return back to you.
Failure symptoms
We have seen power supply board BN44-00162A fail in several different ways and of course there sure are failures we have not seen.
Probaby the most known symptom is the TV taking a few attempts to turn on, caused by bad electrolytic capacitors; those can usually be seen bulging if you look at the power supply board. This is what Samsung settled a class action lawsuit for, even though this is not the most serious and not the biggest issue with the TVs using this power supply board.
Either way, if your power supply board has bulging output low-voltage capacitors we recommend you replace them yourself or bring it by any electronic repair center and have them replaced. We do that for $20-$30 a board for walk-in customers (note: prices are always subject to change) including the parts, as long as they are the usual low-voltage (up to 35V secondary side capacitors) and not the big ones for the mains or sustain voltage (as they cost significantly more).
Another mostly certain symptom of a failed power supply is if the TV is totally dead - no front LED indication, no response to buttons, just totally dead. Most of the time in such cases there will be an open main fuse (near the AC cable connector) and possibly signs of burning on some components on the board like the large green thermistors; the later is not a must, though, as other components such as power transistors or diodes may also fail and not have signs of a failure.
Do not try replacing the fuse - that will not help.
A third failure symptom is the TV clicking on and then right back off or , sometimes, back off after a few more seconds; sometmes you may even see an image for a second. This one is not so reliable of a symptom because many things may cause the TV to shut off and an internal problem in the PSU is just one of them. But we've seen enough and can testify they tend to develp on those boards.
For a bit more on how you can possibly test your power supply and get a better indication on whether it is bad and if it needs this service read our blog article on testing BN44-00161A, BN44-00162A and others like them.
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.
Warranty and returns
We offer 90 days warranty on the serviced module.
During warranty customer can return the board for subsequent repair, exchange or refund, subject to applicability, availability and choice.
Shipping costs to our facility are always paid by the customer, return shipping is always paid by Coppell TV Repair LLC.
In order for any warranty to be valid we must receive boards here in good physical condition, without traces of tampering and with our service tag on them.
Boards returned with request for refund or exchange that are testing all right (we can provide video proof if requested, so sign the board before returning it) are subject to restocking fees comprised of the forward shipping cost and the cost of ensuring the board is functional prior to releasing it for use.
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 or request higher than advertised amount for repair. You will be given the option to choose if you want that or your board back should we determine that it would likely cost more than advertised to service the board.
If you have any questions do not hesitate to ask.
