Re: Optocouplers pc123
Thanks Bud...
Vizio 37L HDTV10A
Standby ok (amber)
No power when switched on...have 5.2v all three pins on connector....no other voltages PB# 0500-0507-0250
MB#3637-0072-0150(2D)...F1-0v F2-5.2v
U8 tests Ok...5.2/3.3/2.1
U33,7,9,2 all 0v
Slowly learning...have several Vizio's with same symptoms...does the 'cold' side of PB remain 'cold' until the main board sends it a signal to 'turn on'?
Guessing my problem may be in the MB...
Thanks for your willingness to teach...

Optocouplers pc123
Have several power boards that have no power/voltage to the 'cold'side....could the pc123 optocouplers be the cause?
Tried testing and think I have several that are bad...any hints?
Have no voltages on the main board other than standby...
Still learning.... -
