It will power up with the radio //etc display lit up and will switch functions however there are only 1 LED showing in each volume indicator and no output to the speakers no matter what I do. I changed out the Relays and the Toshiba selector IC and the usual charred resistors already. There is only one click on power up so my question is what is the startup routine and how is it done _R/C delay circuit I am guessing !
I am thinking it probably needs the power supply capacitors changed out but there is probably a voltage test point or two I can verify if the switcher supplies are working ?? Also I see references to a cap that should be changed that is located near the radio IC so what are the symptoms if this cap is bad or going bad ?--Thanks in advance for any help
