Home Stereo System

I have a problem with a stereo unit. It was gift for my Grandparents back in Christmas 2005. The speakers does not function when I turn on the radio or cd player, but I hear just buzzing when I crank it up. And the tape deck doesn't work too.

Re: Home Stereo System

Sounds like a internal error on the amp itself. Maybe it caught a surge, I had a stereo unit that got zapped by the way it was unplugged from the wall.

Can you repair/replace the CD drive in an Aiwa XR M00U shelf system? All other functions fine.

Repair; I doubt it, Replace; yes, but the hard part would be finding a replacement unit. You would have to open the case to find out what type of connectors it has and go from there. In the long run you're going to spend more time and effort than it's really worth. That isn't a newer stereo system so consider that you've gotten your moneys worth of life out of it. Best suggestion is to put a new stereo on your Christmas wish list.

How to remove timer

If the unit is controlled by a remote, the symptom you are experiencing could be cause by a function only available on the remote. I discovered this with my Yamaha 5-CD disc changer. However, my unit doesn't have an integrated Stereo. Your unit may mean that the remote handles more features. Search for a button that says MODE or AUX. If you still have the User Manual with the system, check to see what these buttons describe as controlling which features. Check back with me.

My stereo won't work. Whenever I try to turn it on, it always turns off saying "protect." How can I fix this?

The protect has come on because it senses an output load problem, Turn the unit off, unhook the speakers and wires from the stereo, now turn the unit on and turn the volume down as far as it will go, this should reset the processor ic, if the word protect stays off you have a short in the wiring or bad speaker. If the protect comes back on with everything unhooked the problem is in the audio output ic pack in the stereo and will require a technician to remedy.

The screen says ''protected'' and the goes off.

It sounds like the stereo functions for a little while, then shuts off. This is the power supply circuit breaker kicking in. It can be caused by a variety of issues, ranging from a faulty component on the circuit board (capacitor/resistor going out of tolerance) to an internal issue with the power supply induced by the heat generated after running for a few minutes.

If the stereo was subjected to moisture or extreme heat, it might function normally after being left unplugged for a few days. But in all likelihood, it may require some internal repair. I had a similar problem with an older JVC bookshelf stereo system and when I took it into a shop for an estimate, the rather frank service rep told me that the costs involved with fixing it could very likely cost more than the unit is worth. I ended up not bothering and just cannibalizing the speakers for another mini stereo system.

What is "Press Power Protect"?

Hi Lois,
Stereo sytems have a protection circuit that alerts you by displaying "protect" when there is a electrical short circuit detected in the system, the most common short happens in a speaker, try disconnectig the speaker wires of both speakers(all speakers) at the back of the system, then play the CD or cassette player(although you will not hear anything with the speakers disconnected) and see if the unit goes into "protect" mode if the problem is still present then you have an internal short circuit and the system will need to be sent in for service or replaced(depending on age,repair costs). I would not recommend investing more than $80 into repairs. Now, if the unit does not go into "protect mode" then one of the speakers or speaker wires is shorted,be sure you check the conndition of the speaker wires before you replace the speakers, then you can replace the speakers(in a pair) and you should be back up and listening! Good luck and Merry Christmas !

Low Volume from right speaker of entertainment center - turntable only

Hi There thanks for your very good desctiption of the problem it really helps to have a lot of detail...

There are Mono and stereo types of stylis cartridges and it sounds like you have a mono equipped into a stereo amplifier..

If there are 4 small coloured wires visible under the stylis then
its a stereo stylis and should work, have a close look and maybe one of the small wires has dropped of the small pins on the back opf the stylis cartridge.

If there only two wires visible then its a mono cartridge and this is why you only have sound from one channel..

So answer is wires dropped of the stylis.
Wrong type of stylis cartridge.
if there are four wires and thay all look connected then perhaps the stylis is faulty and you need to replace it...

Cheers from YU BEUT

Sharp Stereo- Protect Mode??

Try plugging in a pair of headphones. I tried it without the speakers connected and since it found the headphones and they were OK the system came out of protect mode.
