SERVICE DESCRIPTION - PLEASE READ IN FULL!

Coppell TV Repair LLC offers a REPAIR SERVICE for the power supply board  DPS-280LP / 0500-0407-0680 shown on the picture and used in VIZIO VO47LFHDTV30A LCD TV and possibly others.

REPAIR SERVICE means you have to send us your board, which we will test, service (if necessary) and return back to you.

Refer to the failure symptoms section below for some guidance on whether you may need this service.

How does it work

Shortly after placing an order you will receive an email with shipping instructions telling you how to mark, package and send your board to us.

The cost of shipping the board to us is not included in this listing and it is customer's responsibility to deliver the board as per our shipping instructions.

Upon receiving the board we first evaluate its physical condition for meeting our board requirement criteria (see below).

Then we put the board in a testing jig and verify that it is malfunctioning. Exception is made to power supply boards which are usually only bench tested.

If we determine it functional we get back to you. If no repair service is performed and the board is to be returned we retain a minimum diagnostic fee in amount of $20 plus eBay/PayPal sales fees plus the return shipping costs and issue refund for the rest.

If the board is nonfunctional we proceed to repairing it.

We take up to 2 business days for the repair process.

If we are not successful with the repair once we have undertaken it we issue you full refund and cancel the transaction. We do not make money in this case, however we still invoice you for the return shipping of the malfunctioning board.

If board is repaired and tested properly we directly send it back and do not communicate the success. You are notified of the return by an eBay package shipment notification.

Board failure symptoms

There are several different failure symptoms manifested by a failed board and unfortunately some of them can easily be confused with other failures.

One common solid indicator for a failed board is blown open fuse. If you find one you are virtually certain the board needs repair (and usually not just fuse replacement, so do not replace it and try again!).

On this particular board, however, there is at least one common failure we've seen and repaired many times, which does NOT affect the fuses.

It leaves the TV totally dead as there is no standby voltage produced by the power supply board.

One visible effect can be seen on a capacitor near the heat sink as can be seen on the second picture in the listing; the black line going through the middle of the capacitor is from internal burning; sometimes part of the capacitor's body may be missing, but there will still be signs of burning there.

 

 
BOARD REQUIREMENTS 

The board we receive must be in good physical condition and must not have been tampered with, i.e. no apparent traces of previous repairs should show.

We will reject service to boards that someone has attempted repairing and you will still be charged for the return shipping and the eBay/PayPal fees.

As of September 2021 there are listings for repair kits on eBay that do not contain the components we usually see fail on the board. Partial repairs are only more likely to lead to subsequent power failures with possibly new damages not introduced the first time. Take your time and explore your circuits before you put them live!
