If nothing works/lights up at all, check the power supply section first. Check the caps and voltage regulators on board 5 to get started. What have you checked out so far?

I once got a CD5500 with the same problem, no power. I opened it and immediately saw two big diodes on the board that had bad solderings, they had almost come off! Resoldered, and the thing worked like new.

Thanks, I'll keep in touch.

What do you think of its sound quality then?

Also check the solderings of the connectors for the powersupply on the decoder-PCB and the powersupply-PCB. These can also be bad!

I believe it is a thermal fuse because there aren't any proper fuses on the secondary side (just some fusible resistors). First and foremost I would be interested in why it failed - at least check all rectifiers for shorts before powering up. There's a small chance of a failed transformer as well, I guess...

Generally thermal fuses are one-shot so you'll need to replace it. It is probably fine to troubleshoot with a conventional fuse, but I would't put the deck in regular duty until a new thermal fuse is in place.

Yes it is a 130 degrees thermal fuse. Can it be easily extracted?

Wish I knew - never had this problem myself, so I haven't paid attention to where it is actually located. It has a separate part number in the service manual, so I think it is supposed to be replaceable... Sometimes they are just pushed into a recess in the transformer body.

Right then. I replaced the 240V strap with a fuse holder, shorted the thermo fuse and the Beogram lives again, producing music and being stable. BUT the tray doesn't work. The heating was due to a shorted cap (C3).

Some progress...
