Hello

This is my first boom box, I think it's from the 90s and I fel in love with its looks so I brought it

The issiue as the title explains, it's turning on fine but no sound is coming through, total silence.

I tested both speakers separately on my home cinema and they are working fine.

I have to mentioned I am not fimiliar with audio repairs, this would be my first one, I am mainly into laptop motherboards repair so this feels like unknown territory.

I did replace 1 of blown up conductors, which didn't solve the issues, all other conductors look fine

I did notice when I manually push the relay ry601 there is some static sound coming out of the speakers and with max volume on I can hear very faint sound coming out of the speakers as well.

I would very much appreciate it if anyone can help me with fixing this boombox

Maybe the record bar as everything runs through it. This is soft touch so you will have to manually action the REC bar multiple times or replace the belts and press Record / Stop 30 times. Get some alcohol in there as well.

A small update, I fixed the boombox, 2 fuse resistors of 100ohm were bad.
Hi there, I am going through issue with my beloved FH-15R. The right channel starts with sound and then dims to silence. No sound currently. Is it the same issue you have? Thanks.
