Question about Boomboxes

4 Answers

The audio out to the speakers stopped. Is there a resetable fuse or CB in the unit?

This unit has no output to the speakers. The headphone output is ok. The owner said that there may be a circuit breaker for speaker/amp protection built in, which may be bad. He didn't say if he hooked too many speakers to the unit and possibly damaged the amp due to too low an impedence load on it. Is a schematic & parts list available for it somewhere? I didn't think cheepo units like this had any built in protective devices.

A good possibility is a bad solder joint on the circuit board likely to be close to the headphone jack. A circuit breaker is unlikely in this type of unit but if it had one it would likely affect the headphones too. I would look for a broken trace or cold solder joint near the headphone jack. The jack itself could also be bad.

Just to let people know,if anybody still needs to know-:
it has been common practice in the a/v world (which includes boomboxes and other cass.players to include a swiched headphone jack.This is the reason your speakers switch off when you plug in h.p.'s.
If it is really an av model it will have more than one headphone jack.If this is the case,you most likely must use the #1 jack in order for the others to work.

One of the 3 fuses inside the vented back cover may have blown.

Can external speakers be used with the sony cfd s 350 model? If so, do they plug into the headphone jack on top of the boombox?


There is no provision for connecting external speakers. The headphone connector is exclusively for connecting headphones.

I have a Sony CFD-S05. The radio, CD and Cassette are all spinning fine. But there is no audio coming out of the speaker. I have checked all the settings yet no response. Please advise.


their is a good chance the amp or volume control has failed, the only other possible cause is that the headphone socket has got something inserted to cut the sound or has failed

try plugging headphones in if still no sound, its a fail end of life for item

hope it helps a little

Boombox isn't working but the blue light is on.


Unfortuneately the standby light has activated because there is a short in one or more of the audio output ic's, remove speaker wires from back and power on, if no change! outputs need to be replaced, if yes! check wires for shorts and hook one at a time until problem is found,

Ikasu dvd boombox -no sound


If you have power to the unit but no sound, chances are the audio output ic has shorted causing a load, turn volume down, power off, remove speaker wires, power on, if standby light stays on audio output ic needs to be changed. If however the standby light changes or goes off it indicates a short in the wires or speaker issue, hook up one at a time to identify the problem one.

Cd boombox and headphones


HelloWhen a headphone pin is inserted into a headphone socket, it is normal that the internal speaker of the system will cut OFF. It is normal operation, and not a fault. The speakers of such portable sets are wired such that it should cut OFF when headphone pin is inserted into it. We inserts headphone pin to hear the reception or CD music personally. So there is no need for an output from its speakers. Isn't it?

Jack for headphones


Whether your unit has a jack for headphone or not I don't know. But if it has sockets for line out it can be of some help. Line out sockets provide the output from preamplifier section and in many conventional audio systems the same is the substitute for driving headphones. So you can try connecting your headphones to the line out sockets using an adaptor pin.
NB-The preamplifier of all audio systems are not able to drive headphones. Only some can. But if you introduce a headphone amplifier between the line out sockets and your headphone it will SURELY work.
