YOUR DIFFERENTIAL AMPLIFIER IN THE FRONT END OF THE POWER AMP STAGE NEEDS TO BE CHANGED.
USUALLY THIS IS A DUAL TRANSISTOR WITH EITHER 5 OR 6 LEGS,OR AN IC WITH 8 PINS(4+4)

Hello,
if you connect the boombox direct to the your mains of 240v, the appliances will blow up , to avoid that you need a step down transformer to connect the boombox before it goes into the mains source. you do not need any adapter, only if you want to use battery that is when you to swicth to 12v

That is a dirty pot switch.. The volume adjusting pot gets dirty.. Two things to try..

1.) With the unit off - spinn the volume min to max many many times at a rapid pace.. This sometimes will displace the debris in the pot..

If that does not work --

2.) Get some "tuner cleaner" in a spray can.. At Radio Shack or a similar store.. Lay the radio on its back so the volume knob is facing up.. Pull the knob off carefully.. Use short controlled bursts of the spray.. A few sprays and spin the knob min to max several times and repeat..

Good luck..

PLease dont forget to rate for your free question..

A Lasonic 931 ? It has probably been taken apart by someone before you and may have unplugged the power feed from the battery compartment. Remove the rear panel then check the two wires that come from the battery box are connected to the circuit board.If not, then check to see where they go on the board, it`s not hard to do.Look for the little tabs they slide onto..

same happened to me. it might be the battery circuit or the batteries many times fall out of place so they dnt work. call lasonic or send it back for a new one for free like mine

Hi,

It only plays Tapes.
