If your Sony KLV-40U100M is flat out dead, no power, no LED, no nothing, then you may need this service


Ideally, we would suggest that you eliminate the power supply as a potential source of the problem before shipping the board.

If you are handy with simple electronic operations you can actually do that by yourself by measuring 5V standby at the bottom pin 8 of the main board ; having 5V there and TV still being dead when you try to power it this is a strong indication that you have a problem with the main board. The test does not exclude the chances of other problems with the power, but pretty much indicates a problem in the main board.

If you can not or do not want to take this measurement you can still send us your main board. We will do it anyway.

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.
