Mini stereo system shuts off when i turn the volume up, what's wrong with it?

The problem is in the audio driver or output stage which is normally an ic semiconductor, it is recommended that a technician look at the stereo to assess cost.

Hi there,

When the word PROTECT appears on this display, this means the unit has detected a critical fault which could potentially cause harm to your stereo system.

The most common cause is a short circuit somewhere - something even as simple as loose speaker wiring could cause a short, triggering the Protect message.

You will need to determine if there is a possible short somewhere, so I recommend you start by firstly turning power OFF, disconnecting all speaker wires, then turn unit back ON.

Operate the stereo (without speakers) and turn volume up:

• If Protect message appears when turning volume up, then stereo unit itself has an internal fault
• If no Protect message appears, then suspect the speakers may be causing the issue.
• Reduce volume and turn unit OFF

Re-connect speakers (ensure the connections are secure), turn unit ON:

• If turning volume up triggers the Protect message again, there is an issue with the speakers or connections

Hope this helps.....

Yes.

NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING.
Turn the volume control to something medium.
The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

SEEMS LIKE YOU ARE TRYING TO PLUG INTO THE HEADPHONES JACK AT THE FRONT ! NO GOOD . YOU NEED TO HAVE STEREO ON. AND USE AUX. TO DO THIS pLUG IN YOUR MP3 PLAYER WITH 3.5 STEREO JACK OTHER END BACK OF STEREO INTO AUX. RED AND WHITE RCA PLUGS.
THIS LEAD COSTS LESS THAN $7.00 AND THE SOUND IS VERY LOUD THEN. !
I DID IT MYSELF AND AM HAPPY WITH IT .

are the hooked up correctly positive and negative whats the ohm load of the speakers and amp could be a short in your speaker cables
could be many different problems

Protect is a safety feature so that you do not blow your speakers. However with it hooked up with the computer you may have surpassed the max output. If it still does this with out going through the computer, it has been damaged.

The click is a relay. The 12 position is obviously past the max you should be applying. Keep it below that and you should be fine. Quite often the 12 or 1 position is the max output for a receiver. It depends on a lot of different factors but in your setup 12 is It.

it can never be too loud

I had this same exact problem when my last older Kenwood Marine stereo cooked itself while I had it up loud for a few weekends on the lake. (smelled like it had burned inside). I went out and bought a new Kenwood KMR-550u stereo deck. (I do not have an additional amp). I hooked it up to the exact connections where my older Kenwood stereo unit had been hooked up, as I never had a problem with this for the past three years until it failed after smelling of burning elelectrical. I had chalked the problem up to heavy rain we had one day. Every time I turned up the volume, sometimes up to 27 out of 35 possible, or 29, or 32, the stereo would suddenly shut off as if I had turned it off. After a few seconds the stereo would come back on, but unless I was quick enough to turn down the volume it would do it again right away. Of course on a boat, we were beached in a cove and the engine was not running when I encountered this. I searched the internet finding hundreds of similar complaints and several dozen theories of all types, but only a couple that pointed me towards the power (voltage) idea as the problem. I put a volt meter on the positive & negative wires powering the stereo. I watched as I gradually turned up the volume, the voltage on the power wire gradually decreased from 12.5 volts, down into the 11 range, and as it hit 10.9 or 10.8 volts it shut off typically around a volume of 32. The red power wire in my boat that never seemed to have an issue with my old stereo until it fried was determined to actually be inadequate for the power flow for the new Kenwood, and probably was the culprit of my failed older unit. I offer this sound advice: Run a new pair of positive & negative wires directly from the battery (with an appropriate fuse of course (the deck has a 10 amp fuse in it's back so I would use that at the battery) to the stereo. Check the voltage as you turn the volume up into the high 20's and low 30's to ensure you are still getting voltage in the mid to high 11-12 volt range. The stereo is designed to require a minimum of 10.8 volts to operate, and when it drops below that it protects itself and shuts down.

open it up then plug it in. when you press the power button see if one of the large white boxes (there are six in a row) lights up red.
