Bought an Arcam AVR400 FMJ with no sound and no VFD display. I've plugged in to TV and it has display.
I've checked the VFD and it's toast, I don't know where to source it so if anybody has suggestions please let me know.
However, the main issue really is the No Sound to speakers.
I have connected a signal generator to the RCA CD input, and signal stops at the IC101 Renesas R2A15218FP IC. -7V and +7V power supply is there. On this IC101, mute is on pin 51, Clock on pin 50, and Data on pin 49.
Pin 51 - mute is logic low (no voltage) so I'm guessing this is not a muting issue.
Pin 50 clock - and Pin 49 data - however is a different issue. I don't get any signal on them, I tried scoping them on an older analog scope, and nothing.
Anybody has any idea if it's the IC itself or should I look somewhere else?
I have crossposted this on another forum, hoping to get more expert's opinion.
Thanks.
