SERVICE DESCRIPTION - PLEASE READ IN FULL!

Coppell TV Repair offers you a REPAIR SERVICE for the SONYY power supply board E135516 as shown on the picture and used in the 50'' plasma TV HP PL5060N.

REPAIR SERVICE means you need to send us your malfunctioning power supply board. We will attempt to service, test and return it back to you.

Failure symptoms

It is not exactly trivial to diagnose the power supply board as faulty without additional appliances.

This particular board has an automatic turn-on feature, which causes it to automatically activate all of its circuits upon connecting it to AC.

This is a relatively simple way of testing the board, but it comes with some conditions.

First, all other connctors must be disconnected from the board (technically not all, just the ones that override the automatic self-activation, but it's easier to remember it that way).

Second, the board's highest voltage circuit - the Vs - needs a minimal load in order to stay active; without a load it raises output voltage until the over-voltage protection kicks in and shuts the power supply.

In other words, if you connect the power supply board ONLY to AC and nothing else then the normal behavior for the board would be to click and 2-3 seconds after that to click back off.

If you provide appropriate load on the Vs to GND pins, however, it should stay reliably on.

THe most recommended load are two 100 watt bulbs connected in series.

In reality the easiest way to provide load is to connect the YSUS board to the power. The problem with that approach is that *if* the YSUS board is bad then it may trick you into thinking it's the power supply board that is bad.

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.

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.

If you have any questions do not hesitate to ask.
