    I'm repairing a 32" Vizio TV pulled from a trash can. I believe I've identified the issue being a regulator to the processor. Problem is I'm having trouble identifying the part number, and a suitable replacement,

    It's a SOT-223 package with 0341 in the top line. Under it is 912T63. No manufacture part identifications.

    Basically my issue is the TV will power on with no display, as the LED does come on. But will not turn back off. (Common issue with these things usually indicating a bad regulator.) All power from the supply is good. This IC is supplied by a 3.3v regulator. ADJ pin is tied to ground. I just need to see a data sheet to make sure it's not a fixed regulator @ 1.2v which is what is coming from the output. I don't believe that's correct. Any help would be appreciated.

    Have you tried to find a service manual or schematic diagram for the set?
