If your Sanyo DP55360 shuts itself off randomly or (often) immediately after being powered on or when you increase volume this is probably the repair service it needs


Coppell TV Repair offers a REPAIR SERVICE for a common problem found in Sanyo DP55360 / P55360-00 LCD 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 probably need this repair service if 1) the TV tends to shut itself off at random times while working; and/or 2) the TV shuts itself off immediately upon powering on - it may show the Sanyo startup screen for a short time or , sometimes, it may not even manage to do that; this is often observed after a failure of the first type has happened. Upon three unsuccessful startup attempts the TV locks itself in protection mode and needs to be disconnected drom AC for 30-40 seconds before power attempts can be restored.

If your TV does not have those symptoms 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.

Required modules

To use this service you will need to send us the main board as shown on the picture.

It is accessible by taking the back cover off the TV which you will achieve by unscrewing all the visible bolts on the back, which aren't few, but are easy to see and unscrew.

You will need 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.

Some connectors have snap-in locks, so you will have to press the plastic levers to release them before pulling.

Pay special attention to the LDVS cable connector located just above the Video Input 1 (to the left of it on the below picture since it is turned sideways) and facing sideways. This is a delicate connector which has snap-in locks on both of its ends.

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!

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.
