Hi.

I have a unit that after a possible fault in wiring do not have any 5v for TPS or 5v supply. Messured agains ground i get a very short blip of voltage, then nothing.

I suspect the 5volt regulator is dead. My question is, how I go about finding a replacement and I want to make sure that the one I think it is is the right one.

I think i have found this component to be the 5-volt regulator, correct? The circled one.

Is that a zener diode next to it back to ground? Could this also be defective?
