Default Broken cassette radio

I have a broken cassette radio that I want to fix but need direction. It did work when I bought it but I accidentally left it on overnight because I fell asleep. Now when I plug it into a power supply I hear nothing moving at all. I can't remember the model but when I'll find out I'll say.

First thing would be to try the radio. If it works, then you can eliminate the power supply, amplifier and fuses. If it is completely dead (no power light or radio or anything), then you should check to see if the fuse in the plug is blown, and replace it if it is. if the radio is working, you should then open the device up and look at the cassette mechanism. The motor may have stalled, and you may just need to spin it to get the device to work again. If not, then check to see that power is being applied to the motor with a multimeter, and if there is no power applied, then check all of the switches in between the motor and power supply to see if anything is not making good contact. if there is no voltage at the power supply output, then it is the supply that is dead.

What is the make and model of the ptoblematic casseiver?

And how old is it?

Problem could be something like an age-perished drive-belt.

On a different tack I wondered if a thermal fuse in the mains transformer might have gone open circuit.

As Monty says, if the radio works,. well its not power supply... but if it is 100% dead then measure on ohms between live and neutral of the mains lead with it NOT plugged in of course. If open circuit you have a problem.

If this is a portable radio-cassette player, try running it on a set of batteries rather than the mains.
