I found out that it is the chip inside of the unit, its hard to be fixed and it is not guaranteed. I am possibly swiching unite, an upgrade actually, for only about $60 or $70. I just opend up my surround sound about two weeks, but bought it in 2007. Panasonic referred me to a svc agent 52 miles away from me and they do not even have an inhouse svc tech and they only fix electronics you purchase from them!!!...I THINK PANASONIC NEEDS TO BE REPORTED AND POSSIBLY CONSIDER THIS A RECALL!!!! would someone else respond and let me know what they think or if they had even fixed there error message.

Check and correct the speaker cord connections. If this does not fix the problem, there is a power supply problem. Consult the dealer.

Loud popping from speakers

If the unit shuts down after you hear a pop, you have DC voltage on the speaker output line. If it doesn't shut down, is it popping in all speakers, or just some?

Check the impedance (resistance) on all the speakers and the speaker wires themselves.
Power up the unit with no speakers or inputs attached at minimum volume and see if it still goes into protection mode.
Most speakers should measure between 4 and 8 ohms for most systems when disconnected from the receiver.
If the unit says PROT even with no inputs at minimum volume with the speakers detached, then there's a problem with the amplifier itself, probably in the output section.

When playing DVD, it's sometimes display 'PROTECT' and stop playing.

Check if you receive the error when playing any DVD in particular.

What happens when you take out the DVD and try playing it again? Does it play

This protector error denotes several possible problems. Heat, volume level and incorrect DVD settings may be the cause of the problem. The following steps will help you correct your problem and rid your amp of its "Protector" error.

  • Examine your volume setting to be certain that your volume knob is not at maximum. Having your volume cranked too high can cause the capacitors to overheat, shutting down the receiver.
  • Unplug your receiver and disconnect your speakers from the terminals on the back. This will allow you to determine if the error is internal. Plug your receiver back in and look for the same error message. If you continue to get the protector error without having your speakers connected, you may have an internal electrical problem. In this case, contact Sony about finding a repair center.
  • Reconnect your speakers one at a time. The order of connection doesn't matter. When reconnecting, be sure that you do not have your positive and negative speaker wires crossed in any way. After each connection, test your amp by running it with a source. Give each speaker a few minutes of power before connecting the next one. This will help you isolate which speaker terminal is causing the error. When the protector error returns, take note of which speaker connection caused it. Check this speaker wire for shorts or torn shielding.
  • Examine your ohm rating of your speakers if you have no shorts or wiring issues. Sony receivers are not compatible with speakers lower than 4 ohms. Connecting a lower ohm-rated speaker will cause an error.
  • Turn off the surround sound option if you have both your A and B position speakers in use.
  • Keep your receiver well ventilated. Overheating due to poor ventilation can also cause Protector errors.
  • Examine the sampling frequency of your connected DVD player. If the error only occurs when you watch a DVD, the sampling frequency of the DVD player may be set too high. Check the sampling rating in your receiver's manual and in the DVD player

My Samsung Home Theater System Shuts off about 2 seconds after turning on. The display says PROTECT and then shuts off. Any suggestions?

Hello David - That message is telling you the system is shutting itself down because of some electrical abnormality that could damage it or a situation causing it to overheat.

I suggest you first unplug the unit and let it sit for an hour or two. Power it back up. If the warning is still there power it down. Now would be the time to consider whether you have made any changes to the system, even anything as small as moving a speaker.

The most common reason for the error is that there is a short somewhere, usually in the speaker wire itself or at the connector to either the speaker or the system. Overheating is not the issue because of the short time between power up and the message. Detach everything that is attached to the unit (devices and cables/speakers) and power it up again. If the error persists you have an issue requiring service, hopefully under warranty.

If it doesn't that's a great sign and the next step is to attach everything back ONE device/cable at a time, powering the unit down before you attach the next device/cable. Be extra careful with the cable attachment and while you're handling the cable look for any visible abnormality with the cable, bare cable, cracked connector, etc.

Obviously if the error returns right after any connection the problem is right there, most likely a speaker cable and the fix is to make sure the cable is not shorting at the connections to speaker or receiver and if that can't be found visibly replace the cable with a new one.

Good Luck and Thanks for using Fix Ya.

Main unit will not stay on

check to make sure none of the speaker wires are touching the case. If not, unhook them all and see if problem persists. If it does then the amp is damaged. If not then plug one spkr in at a time and check to see which one is causing the problem.

Chk spkr error message

Your problem is the output IC's The case where you say the speakers buzz tells you theres a short in the audio outputs. If your unit didnt shut off, the speakers would fry and the unit would also smoke. These are solid state devices and are soldered in, and are not concidered user serviceable parts, unless you know how to solder and trouble shoot Stereo systems. This is a job for the pro if you want it fixed. Good Luck
