20 Most Recent JVC HX-C6 Shelf System Questions & Answers

The problem is that the output amplifier section has a problem and the protection circuits are shutting down the system to prevent further damage. This should be a simple repair for any local service shop. If you can't find someone local, look up at the JVC website for an authorized service center. Use your zip code to locate the closest one.

i have a jvc stero and every time that i turn it on ...it show protect and shuts off!

i assume the power comes on and there is no audio. more than likely the audio output ic is blown or it may just have bad connections. the ic is usually the largest component on the circuit board mounted to a heat sink. you can write down the number and try to get one online or at anelectronics wholesaler. also look to see if any capacitors are swollen or blown. if so try changing these first but if that doesnt work shut the unit off right away or they will blow again.

Unplug the speakers from the stereo, then try and power it on. If your problem continues, check the internal fuses on the stereo.

How do i fix that i get the message on my cd play (JVC HX-D7) and it says PROTECT and shuts off by its self what do i do to fix the problem ?

The audio output ic generates the audio to your speakes producing sound.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

Resolve the threat and it will stop protecting itself.

Sadly, the manual doesn't address it directly.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

google stk428-610 ic an stk428-640 ic an replace them , they have to be solder in , don't try this if u don't have experience

make sure speakers are properly wired.try to reset the system by holding the ryhhm button down.

If the unit goes into into protection it usually means the amp is blown. It would need to go into a shop for service if the repari is not cost prohibitive

as the most common problem u have over heated the unit about a 100 dollar repair unless u have the knowledge to fix eletronic .parts stk mono always check speaker wireing 1st.

check speaker wireing if thats not the pro then u may have over heated the unit.the stk xxx exc are pro bad youll have 2 open that bad boy up.

make sure your speakers are connected in the right slots (output) Sometimes my radio did that especially if i turned it up louder and the wires wer not connected correctly. (also , your radio might no be recieving enough air so it gets hot and turns off.) Your radio might skip because the vibrations of your speakers' distortion is too high. (try moving the speakers farther from your Radio)
