SERVICE DESCRIPTION - PLEASE READ IN FULL!
Coppell TV Repair offers a REPAIR SERVICE for some common problems found in Sanyo DP42740 / P42740-03 plasma TV.
REPAIR SERVICE means you have to pull out and send one or more modules from your Sanyo TV so that we can service, test and return them back.
You need this repair service if 1) the front green LED of your TV comes and stays on for 15-20 seconds, then turns off for 1-2 seconds and then keeps cycling like that, but the display never comes; 2) the display comes on for a brief few seconds, then the TV shuts off; in some models the display may not even come on, but still the relay clicking on and off and the green power LED activation and shutdown can be easily observed.
If your TV does not have those syndromes the problem may be elsewhere or may still be on the same module(s), but different from what we are used to seeing and prepared to resolve for the listed fixed price. Consider using our remote diagnostic service to get a better idea of what the problem might be and what would we do in your place.
To use this service you will need to send us the main board J4HEF as shown on the picture.
It is accessible by unscrewing the two bolts that hold a panel on the back of the TV and sliding off the panel to the right.
The board itself is on the right side (the one to the left is the power supply board). All you need to do is disconnect the cables from the board (simple pulling, but make sure to hold the connectors, not the cables) and then unscrewing the bolts holding the board itsef.
IMPORTANT: Sanyo often releases several different variants within the same major TV model label.
For example Sanyo model DP42840 chassis P42840-01 is completely different internally from chassis P42840-02 of the same model.
It is important that you double check the chassis of the TV you are repairing against the one in the title of this listing and also (for double protection) comare the main board model and look against the one listed and shown here.
Coppell TV Repair will not cover expenses caused by confusion on customer's end!
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.
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.
