SERVICE DESCRIPTION - PLEASE READ IN FULL!
Coppell TV Repair offers a REPAIR SERVICE for the main board N4PL as shown on the picture and as found in Sanyo DP37649 / P37649-00 37'' LCD TV.
REPAIR SERVICE means you have to pull out and send the main board N4PL from your Sanyo TV so that we can service, test and return it back.
How does it work
You send the board to us wihtout paying anything in advance and get a payment request depending on what we find and eventually resolve (or fail to resolve) on the board as follows:
- If we find the board to be in working order we charge minimal diagnostic fee (up to $25) plus return S&H for the board;
- If we find a problem with the board and we resolve it we send a payment request for the amount specified on this page (a flat fee rate);
- If we find a problem on the board and we can't fix it (for whatever reason) we do not charge you parts or labor, but you still have to pay the return S&H costs in order to receive the board back, if you want it back.
In all cases you can also send a prepaid return shipping label and cost of return S&H will be accordingly substracted to the payment request sent to you.
To start the process click the "Initiate service request" button at the top right corner of the page.
Failure symptoms
Your TV may need this repair service if your TV does not power on or/and cycles every 30-40 seconds.
It is important to mention that while symptomatic for a main board failure this indication is not a definite proof of such a faulure; failure in other boards, e.g. a sustain board, may cause the exact same symptoms.
One thing you may want to do is panel test (forcing the plasma controller to display pattern independantly from the main board) and if that passes all right then the chances of you having a bad main board are significantly increased.
Required modules
To use this service you will need to send us the main board N4PL 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!
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.
Payment
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.
