Hello forum. I have a a-s700 on the bench. No remote!() unit is on dbt.
When power switch is turned ON…it just blinks(protection..?) dead dilence…no relays….no smoking….nothing.
I have no power going to the transformer……see scat’. No voltages coming out of the transformer either. RY251 is not closing …ideas?
I have testet components on the ‘power in’ board…..they seem good. Fuses are good….
Advice help appreciated. Thanks.
