CXA3740M Sony PWM / PFC driver IC (Sony KDL-55BX520 APS-311 and others)

1 pcs new Sony CXA3740M driver IC used in various power supply boards such as Sony APS-311

Coppell TV Repair LLC offers you Sony IC CXA3740M as shown on the picture and used in Sony APS-311 and surely other power supplies by Sony.

Using those ICs we have successfully fixed APS-311 power supplies that do not raise the PFC voltage on the mains filter capacitors to 390V upon signalling the board (PS-ON).

ICs are sold as NEW to us; they look new and we have not experienced problems with them as of end of 2017.

Using this component requires advanced soldering skills and equipment for SMD soldering.

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.
