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.


Advertised price is the maximum price you will pay and includes the return shipping costs within USA. Surcharge applies for international returns.

You start the process through the orange button on the page by filling a short form with your contact information and a brief description of the problem.

An email with shipping instructions is automatically sent once you submit the form to the email address you provide.

You then package and send the board to us. You pay for the shipping to a carrier of your choice and nothing to us at this point.

Once we receive the board and open the box we test it and act depending on what we find out.

If the board arrives in working order you will be charged with a a diagnostic fee of up to $25 plus the return shipping costs, i.e. less than the advertised repair cost.

If the board is bad then we attempt to repair it.

If we succeed we send a payment request for the amount specified in the listing.

If we fail to 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.
