Repair kit for SONY KDL-40EX400, KDL-40EX500, KDL-32EX500 power supply APS-254 4-281-977-01 - 2,6 or 7 blinks error codes

A DIY repair kit for common problem in Sony KDL-40EX400 KDL-40EX500 LCD TVs resulting in 2,6 or 7 blinks

Coppell TV Repair LLC offers you repair kit for a few common failures we have seen and successfully repaired ourselves in power supply board APS-254 used in Sony KDL-40EX400, Sony KDL-40EX500 and possibly other models.

The kit contains parts that address several different failures, which can happen individually or in combination. We have seen a bad CXA3809M cause different failure symptoms on the outside. What this means is that you do not have to necessarily have to replace all components from the kit, but in case you do not know how to test a component on the board we still recommend replacing it.


2 blinks, 6 blinks and 7 blinks from the TV when attempting to turn it on have been observed in different situations before applying this kit, which resolved them; this is not a guarantee it will resolve any other failure resulting in the same error code, of course.
A definite indication you need this kit is an open R6324 or shorted Q6302 or Q6303.


Replacement components for IC6301, Q6302,Q6303, R6342 and possibly others (contact us if you receive component that you do not map to anything)


This repair kit requires basic to intermediate soldering skills and some experience. No help is offered or provided for the soldering process itself.
Always use precaution and make sure you are only working on boards that have been discharged to harmless level of energy before operating on them!
Use a repair service by professionals if you have any reason to doubt your skills or equipment!

ATTENTION INTERNATIONAL CUSTOMERS: If your order is accepted by our store and your address is outside United States you may not be able to track package delivery progress once it leaves the country. The United States Postal Service (USPS) does not provide tracking information to some countries unless the shipment is the most expensive Express type, which is usually too expensive to justify using. You can accept that condition and strip Coppell TV Repair LLC of responsibility to the delivery status of your package provided we show it was shipped and processed by a courier in a timely manner. Or you can contact us prior to ordering and inquiry for delivery confirmation shipping method, which, again, usually costs an arm and a leg compared to the simple USPS First Class shipping.


Coppell TV Repair LLC does not guarantee that this component/kit will resolve the problem in your TV. It is offered based on experience and technical information available to us at the date of publishing of this listing and known to be more or less common for the listed models.

As every failure can be unique so can be every repair task.

In addition, while giving the repair task a rough classification in terms of difficulty, Coppell TV Repair cannot evaluate each individual's qualities to perform the job or prevent operational errors even from skilled technicians.

As such, no warranty is offered on this product.

If you would like warranty please see if a REPAIR SERVICE is offered instead of a kit. Unless otherwise noted all our repair services do come with a standard 90 days warranty.
