Hi,
I've been puzzling with this receiver for a while now. Is there a specific IC I should be looking at that generates this acpwr_det voltage?
My receiver is showing this voltage as 3.0V instead of 3.3V.
After searching here I saw that the 3.3M is not generated from the OP(3) board. Is it the same for ACPWR_DET?
Receiver works perfectly fine when I am able to switch it on, but cuts off after a bit of running. I sometimes get a PS3 fault, but not all the time.
Thanks in advance.
Edit.
The voltage readings on the onboard sensors all show within range, the PS1 is not constant, it reads from 114-118
PS2 is constant at 120
PS3 is constant at 154
However on the protect faults. PS3 has an entry showing 95. So it would have been low.
After going into no protect to check the voltages and faults, the receiver switches on perfectly fine and runs perfectly fine for a while, then switches off with usually the PS3 fault. I haven't seen anything physically wrong with any of the caps, and have even replaced the usual yamaha caps just in case.
The 3.3M voltage is perfect all the time. It's just the acpwr_det that is low.
