Re: Vizio ADTVD3613XA6 PS for E500I-B1 oops help!

Maybe someone who understands this part of the circuit better than me can give me a reasonable value to start with and I'll change it until it's right. I'm thinking they use this shunt regulator instead of a zener?...

Hey guys I've been repairing this PS board for a relative and after reading all the threads about this model and looking at the great circuit drawings budm had traced out for others I thought I had a good chance of fixing it. Started with the usual TV will not turn on, power button lights then fades out. found 5v SB at 5.13v B+ at 170v with set off all other pins 0v. After pushing power button no change except ps_on 2.95v no other change. found IC9101........LCS703LG and IC9801.........LD7591 both get vcc from ps_on by way of q9101 thanks to budm and his tracing! found vcc very low at both chips...

What did you mean by that? Were they a bad company "before they shutdown"? I was thinking of sending a Vizio power supply board to them for repair later this week, is that maybe not a good idea?...
