Hi, I need Your help with Yamaha RX-V467. This receiver don´t turn on, voltage on the power switch (SW472) is 0V, PSW_DET pin of IC20 (CPU) is 0V too. Every VCC pin of the CPU have 3,3V. I replaced capacitors on Video (2) and Video (3) board: C3701, C3717, C3802, C3803. Transformer is ok. Here are the measured voltages:
+3,3M 3,3V
ACPWR_DET 2,54V (CB382)
ACPWR_DET 2,54V (CB381)
RESET 3,3V
PRY 0V
DEST 0,02V
Thanks.
