I have a Yamaha CR-1020 that I bought thinking it was "restored" and refreshed -
but is now exhibiting the following symptoms:
I first noticed that I could no longer hear the relay clicking after powering up.
I pulled the cover to take a look. From watching another YouTube video, I gently pressed on the
loudspeaker relay box (clear plastic cover) with the eraser end of a pencil and when pressing forward
I could then hear it click. When I did this, I could then turn the volume all the way up, and hear the music coming thru faintly.
A few minutes later during one of my manipulations of the relay box - the relay emitted a green spark ... and then no more sound at all - even at full volume.
The relay has the following written on it:
HC-HP DC 12V - F
AP3421F
7A1/6HP125 250V AC
3A 30VDC 21217 H
Made in Japan
My first thought it to simply try and replace the relay. Second thought is what caused it
to spark and shut off, and should I be trying to determine that - before simply replacing it....
Any help would be greatly appreciated. I am kinda new at this - just learning about cleaning
parts/pots, etc with Deoxit. If I am in over my head, will take it to a local tech - but wanted to see
if maybe it was something within my capabilities first ....
Thank you,
