Thanks for your efforts, I now have an idea of what to look for. Also, 2 cool things that I will be doing in the future, drawing a simple outline of unit and taping screws: same screw- same hole=good. Also the lint roller from Ikea. Nice.

Thank you so much for your kind words. It really prevents a lot of headaches those drawings with screws taped to it ;). If you could subscribe to my channel, I'd appreciate it!

Hi Paul, that's a nice CD player! Does it sound like it is reading the CD? - does it start to spin when you close the lid after a cd is inserted. If it doesn't react at all to any of the other buttons I'd check the connections between the board containing the button switches and the main board like I did in the video first. I had another CD player where the connections between the two boards on the front of the machine were loose because of mechanical stress by the buttons. Loose connections or dried solder joints are very often the cause of problems and they are easy to detect with a multimeter.

Any fried diodes on the power supply board? Have you measured them using a multimeter?

What size are the diodes?
@repairchannel 10 ай бұрын
I used 1N4007 diodes as a replacement for the fried ones
