Coppell TV Repair LLC offers REPAIR SERVICE for power supply board Samsung BN44-00190A / PSPL531801A 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 BN44-00190A / PSPL531801A 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.
HOW DOES IT WORK
To have us examine and possibly repair your board(s) you need to send them or bring them to us.
Start the repair service request through the "Initiate service request" button on the page. Repeat customers are advised to log-in and new customers will have to fill-in a short form with contact information needed for communication and invoicing.
An email with shipping instructions is automatically sent once you submit the form to the email address you provide; it is also shown on your screen.
Following the instructions you package your board(s) and attach the first page of the shipping instructions so that we make a link between the boards and the service request when we receive your package.
You then send the board as shown on the picture to us. You pay for the shipping to a carrier of your choice and nothing to us at this point.
Presently we do not charge in advance, but only after inspecting and possibly servicing the board(s) we receive.
The price shown is for evaluation, repair, test and return within USA of the boards listed in the title or explicitly named in the listing, provided they meet our requirements upon arrival (see related section).
Boards returned abroad tend to have higher shipping cost that will increase total cost of service beyond the amount shown.
Once we receive the package and open it we inspect the board(s) sent.
If the board(s) do not meet our criteria we communicate the problem with you and offer options, the first of them being returning the board(s) back for sole cost of return S&H. Other options may include surcharge for board restoration, board replacement, change of pricing or warranty terms etc.
We may not give any options and simply reject to service a board that was damaged beyond repair (see example here).
If the board(s) pass our criteria we conduct test to determine functionality.
If test passes OK and board(s) appear in working order we communicate that and offer options, among which returning the board(s) without change; we invoice a testing fee and return S&H charge.
We test all boards that are being sent and for every board we test we assess testing fee as described.
If board(s) come in assemblies that require additional dismantling on our end (i.e. with more than what is shown on the pictures) we reserve the right to charge up to $10 for dismantling and re-assembling what was sent plus eventually additional shipping costs if resulting assembly requires larger box and/or is heavier than the regular board as shown.
Boards that test out bad are analyzed and we attempt to repair them.
If we succeed we send a payment request for the amount specified in the listing.
If we fail to repair the board(s) we send you an email with details and usually only request that you pay for the return shipping and nothing else.
Please make sure your TV has the same board before proceeding with this service or contact us if yours is different to see if we offer repair service for it.
SERVICE TIME
All packages we receive are placed in a FIFO processing queue.
It takes 2-5 business days for a package to make its way from the back to the front of the queue.
Once picked up for processing, we make money if we manage to fix the board(s) inside for between 30 and 60 minutes.
Of course that isn't always possible, not to mention sometimes there is more than one board in a package.
Add to it that we can't know how many packages we will receive at any given day, how many boards will each contain and how bad the damage on them could be.
Please do not call us a mere few days after you sent your package to inquiry about the status of your service...we just do not have the resources to be giving the same answer to everyone and it only slows us down!
Look at the tracking number, see when it was delivered, give it at least 2-3 business days (preferably four) and if you have not heard anything from us then contact us saying the package was delivered on this and that date and we'll go look for it.
It's in everyone's interest that we work as fast as possible and interrupting technicians (who answer the phones) to make them go search for package in the queue only to tell you it's there doesn't help anyone.
WARRANTY CONDITIONS
Unless otherwise explicitly stated elsewhere in the listing the boards we sell come with a standard 90 days warranty.
Customer is responsible for return shipping and Coppell TV Repair LLC is responsible for shipping back to customer. Returned boards subject to exchange, service or refund, subject to availability and agreement by Coppell TV Repair LLC and customer.
Returned boards must carry the Coppell TV Repair LLC identification stamp or label and must not have been damaged, modified or otherwise tampered with in order for warranty coverage to remain in force.
Boards returned with request for refund / order cancellation will be subject to restocking fee covering forward shipping cost, transaction cost and $10 fee for the board testing needed prior to slating it for sale again.
REQUIREMENTS FOR THE BOARD(S) SENT IN FOR SERVICE
The board(s) we receive must be physically intact and must have not been tampered with or serviced before.
The advertised flat rate for repair service is only valid when the above conditions are met.
Exceptions are possible and often applied for minor repair attempts, but we reserve the sole right to judge if and when we would consider a repair minor.
If we receive board(s) that fails the above conditions we will contact the sender and usually offer two options: 1) returning the board(s) for the sole cost of the return shipping; or 2) continuing the repair service at a higher cost in case of success.
It is also possible, depending on the condition of the board, to eliminate the second possibility and just flat our reject having to service the board.
Subject to situation and availability we may also recommend replacement of the board, again at the higher than advertised price for repair.
In all cases you will have the option to receive your own board(s) back for the sole cost of the return shipping.
