We offer a diagnostic and repair service for a faulty power supply in Toshiba 40G300U1.

Coppell TV Repair offers a REPAIR SERVICE for Toshiba power supply PK101V1560I / N236R001L / 75017641 shown on the picture and used in Toshiba 40G300U1 LCD TV.

REPAIR SERVICE means that you need to send us your malfunctioning board that we will attempt to service, test and return to you.

The repair service is not limited to the described failure symptoms. We do what needs to be done to get the board working, provided it meets the below specified requirements.

Toshiba 40G300U1 power supply failure symptoms

Failure in the power supply board of Toshiba 40G300U1 is typically manifested by either a completely dead TV (no front LED, no response to any command) or the front LED responding to power on command and changing color, TV possibly coming up for a while (time may vary) and then shutting down at its own will.

Another popular report we are hearing is the TV spontaneously shutting down without apparent reason. It may sometimes refuse to power on afterwards until it is left to cool off or , over time, just permanently stay off.

Other failures are also possible, of course, and unfortunately some of the symptoms can also be caused by other failures in the TV.

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.
