Repair a Sony Walkman Boombox

Actually, I would first look for loose connections. Has a wire come loose that leads from the battery compartment to the rest of the circuitry?

It's quite common on any of these that use a ' figure 8 ' power connector, for the three pins on the power changeover switch, mounted on the back of the figure 8 socket, to fracture their solder joints, or even for the pins themselves to snap off. It's caused by the repeated insertion and removal of the lead over the years. Depending on which pins go bad, the symptoms can be no battery operation, no line power operation, or just plain dead. Might not be in your case, but it sounds old enough to have this trouble, and I have done many over the years.

Two things are possible:

It may have a switch in the back labeled AC/Batt or something similar. It has not been set to battery mode for portable use.

1. Most, if not all boomboxes with a remote will only power on from the remote when the unit is plugged in to the wall. Try operating the unit off batteries by using the front panel buttons.

Yes I have seen this too. Also if that changeover switch is ok there might be a a problem with contacts being corroded due to battery fluid having leaked into the battery compartment. Richard

Thank You all for your imput. I will try to troubleshoot based on your imput. Wish me luck. Any other comments greatly appreciated. I will let you know how I make out.
