A power surge took out a few components on the power supplies primary. Part U501 is a pmic but it is completely blown and I can't read its part #. I've tried searching for a schematic but there are none available. If someone could identify the part that would be extremely helpful. The power supplies model# is Pk101v0830i. Thanks in advance for any help you guys provide.

Re: Need help identifying component U501 on the power supply of a toshiba 40rv525u
To me, it looks like a Power Integrations TNYxxx chip -- the hard part is determining the "xxx" part. Any clue of those last digits?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search.

On a similar Toshiba TV's board the U501 has these markings:
A6069H
SK942
17CP
It's a seven pin IC.
Board number is: PK101V1000I/FSP245-4F03

OK, after hours of manipulating the picture of U501 using shojimmy photo and searching the FAIRCHILD website.
U501 is made by FAIRCHILD P/N FSB117HNY used in your board version.
The connections of the IC pins on the board seems to match the app notes.
