Repair service for Vizio VW42LFHDTV10A main board - unresponsive TV problem

If upon powering on your Vizio VW42LFHDTV10A the Vizio logo turns white, but the backlight does not come up there is a good chance the problem is in its main board.

Coppell TV Repair offers REPAIR SERVICE for main board shown on the picture and used in Vizio VW42LFHDTV10A and other Vizio LCD TV models.

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

Failure ymptoms

Typical failure indication is completely white Vizio logo turns white upon powering on, but the backlight does not come up and the TV becomes unresponsive and needs to be removed from AC power.

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.


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.
