LETS TRY THIS FIRST,put the unit in standby,then unplug it for 3 to 5 mins,if this doesnt work,then try repeating the same thing,but this time with everything disconnected from the unit(including the speakers)what we're trying to do is isolate the problem to either a external source or the unit itself.let me know if this helps.

Why does my reciver say portect


Does it come up with Protect as soon as you turn it on or does it play for a bit and then come up with protect?

The Amplifier has a Fault and is shutting down to protect itself (If it will jet you play for a bit). Repeated cycling of this will cause a total failure in the Amplifier (If it says protect as soon as you turn it on).

If you haven't got the Technical ability to have a look at it yourself then your only option would be to take it to a service engineer.

If you haven't got the Technical ability to have a look at it yourself then I suggest you take it to a service engineer or wait for a total failure and scrap it.

Keeps kicking off saying protect


Hi rifrandle
To answer your question;
Your amplifier goes into protect mode when it detects a fault or condition that could damage the speakers and/or the output stage.

Often caused by shorted outputs.

Although this does`nt tell you much on how to fix this problem, the best help i can give you at this point is to tell you to have it looked at by a repair shop.

Hope this help good luck

Receiver keeps flashing "PROTECT"


The protect message indicates that a problem was detected in the last stage of the amplifier and that it has shutdown to prevent further damage. Usually this indicates that the output transistors have failed. Any shop that works on audio should be able to repair this. Expect a part cost in the $20-$40 range. Add in the local labor rate for the total repair cost.

Samsung 5-Disc 1200-Watt Home Theater Surround Sound System My Home Theatre System is keeps shutting down by its self. before it shuts down the screen says protection mode and then shuts down. i have...


If the unit shuts down almost immediately without sound, you have an electronic failure of the audio amplifier.

However if you must play the unit up above quiet background levels, you likely have a shorted speaker wire. With home theater systems, you have the luxury of trying different surround modes and speaker level settings. It's not unusual, for example, to have a loose wire strand going to the center speaker. In stereo, the system works fine. As soon as you switch to a surround mode, the amplifier senses the short and shuts down to protect itself.

Check those wires really close - I bet you'll find it there.

My jvc rx-6010v is OVERLOADING?


The very FIRST thing to check is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. (JVC - and others - say SIX ohms, but 8 is the "standard" you should use.) Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: The internal overload protection system you mention is designed to help prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized JVC service center must do this. Note, though, that if you have attempted to "cheat" the system several times, damage CAN be done that requires servicing.] But, before you take the unit in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. Visually inspect connections at the receiver and speakers first. You might find something obvious! If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these "fixes" will work for you. GOOD LUCK!
