OFFER DESCRIPTION – PLEASE READ IN FULL! Coppell TV Repair LLC offers you functional replacement for power supply board DPS-388AP as shown on the picture and used in Vizio P652UI-B2 and possibly others. It was serviced and possibly upgraded to prevent known common known failures for this board. Upon receiving and installing it you can send your old board to receive credit subject to the conditions below. HOW DOES IT WORK You are purchasing a functional module that is same or 100% OEM equivalent to the one advertised in the subject of this listing. (OEMs sometimes release several versions of same module and use them interchangeably). The board you will receive can be brand new, used or, most commonly, a board serviced by us – Coppell TV Repair LLC. Unless it is brand new (which is rare for the modules we offer as we specialize in servicing hard to find or expensive TV boards) it is guaranteed the board will be tested by our staff and there will be a label on it attesting to it. Before placing an order please ensure that this is indeed the board in your set by comparing the number on it. The most common indication that your power supply in your P652ui-B2 is bad is an entirely dead TV. It is not a guarantee, though, and unlike with other common power board failures there is usually no open fuse to indicate the board has undergone a failure. What’s more, the power supply board is often mistakenly taken for bad when it’s actually the main board that is bad; the typical TV behavior in such cases is the TV’s LED indicator would light up when the TV is connected to power, then slowly fade down (as it should) and then upon trying to power on the TV it would light up and then fade down again, the screen usually never coming up at all. This is 99% certain to be a main board, for which we also offer repair service, and not the power supply. 2 The board must arrive in good physical condition allowing subsequent electrical repair and reuse of the board. Sometimes when components fail and burn they also leave burn marks on the board. Most of the time such traces are not affecting the ability to restore the board’s functionality, but in some extreme cases this may be a problem. 3 The board must not have missing or replaced components or have otherwise been tampered with. Exceptions vary from all 3 listed conditions, but we reserve the right to be the judge on whether your board qualifies for an exception.
