Repair service for Magnavox 42MF237S/37 / Philips 42PFP5332D/37 power supply board 996510010206

Service repair for power supply board 996510010206 used in certain Phlips/Magnavox 42'' plasma TVs


Coppell TV Repair offers a REPAIR SERVICE for power supply board 996510010206 (also known as PS-507-PHN, LJ92-01513A or LJ41-05253A) shown on the picture and used in Magnavox 42MF237S/37 and Philips 42PFP5332D/37.

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


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 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.

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.

Failure symptoms

There are several different symptoms of this power supply board's failures.

One is a completely dead TV - no front LED, no response to anything, buttons or remote.
Note this may also be an indication of a bad main board.

Another common indication is a pair of clicks when you try to turn on the television: one that activates the power supply board followed by another one that turns it off.

This may also be caused by something outside the power supply board.

There are two things that will help you increase the odds of having narrowed the problem to the power supply board.

First, take the back cover off the TV and look at the lower right corner of the power supply board, where there's a small sub-modile standing at 90 degrees to the board itself. There is a small LED on that module and when the power supply board is normal it emits steady green light. When power supply board shuts off with an error code that light is blinking.

Second, as this is another common source of a problem in those TVs, disconnect the cable connecting the Y-Main board with the power supply board and try to power on again to see if the TV is still refusing to come on.

Y-Main sustain is the board sitting to the leftmost side of the TV when looking from the back.

It is worth doing the same exercise with the ZSUS sustain board, which is sitting at the rightmost side of the TV when looking at the TV.


In that second case we recommend disconnecting the Y-Main board from the power and trying again; if the problem persists then it is more than likely that you have a bad power supply board, otherwise you are likely having the infamous Samsung Y-Main/buffers failure (which we also offer repair service for).

Typical turnaround time is 2-3 business days.

This is the time it takes for a package that was received to move up the queue and get opened.

Once we open the package we usually have about 1 hour to get the case resolved or we will likely end up losing money on it.

Sometimes, depending on situation, we may leave opened box and make another try on the next day.

Note that it is not guaranteed that the queue will take exactly 2 or 3 days to process. Sometimes - especially after long holodays - it can be larger and take longer.

We do our best, but we have no efficient means of managing the work load on demand.


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.
