I ran an electronics repair shop for 25+ years. When electronics became more disposable, I wasn't getting enough customers so I switched over to small engine repair. My father had taught me everything electronics (no school, just him and me teaching myself), so when he passed away a few years ago, my interest in electronics went with him. Watching this brings me back. I really miss those days. Thank you so much for this!
I have one of those, and the display was half out and the two buttons under the volume control stay on, and also goes into protection mode. I saw a post online about the same problem. They said it was with the swiching transistor in the heat sink markee SD1585. I changed that out, and everything works, but the heat sink still gets hot after a few minutes and the right channel will cut out, but may be just a dirty pot. I don't want to trash it, brcause it was free. I just want to get it working correctly again. The transistor I replaced it with was close as the original one as I could order. I'm not a tech and don't know much about what to check for. I'm just trying to find out the over heating problem, if it's not supposed to. Theres no burned or bad solder I can tell on the board. I'm trying to find out if I'm missing anything. The artical on the problem the other model had, the owner said the overheating problem was cured after the transistor change.
With those signs of running toasty, I think i would be tempted to replace that resistor, assuming its 1/2 watt with a 1 watt resistor, sitting up to get air.

So sorry for your loss. I lost my mom and dad within a couple of years of each other almost 20 years ago myself.
Amazing video while it shows the importance of proper grounding within the circuitry indeed!
finally, back on track
i hope you finished your home improvement thingy
I Got one of those ... I had to replace a few of the tactile switches , but it still plays fine
Good Job👍👍

the speaker wires in the back were making me nervous i know it wasn't touching but it look like it could have and could have caused a short.
:o)❤
Goes...
