CXA3740M Datasheet

[Sevenqi]

Looking for this IC's Datasheet, it's the power supply IC for aps-311 board in SONY KDL-55BX520, TV has no red led on but did have 3.3 standby, no ac-off-det voltage. Like to determin if this IC is good or not first before check the main board.

Thanks

Re: CXA3740M Datasheet

If there is standby voltage, then unplug all the other boards and force the PS on in order to test it. Standby voltage goes to the main board, which is giving you the led. When you press power button, it will send a signal back to the power supply, turning on all voltage rails.
