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 '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.

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

Speakers Output comes from these IC'sDetermine each output stage and measure DC offset voltage.If it is over 0.7V , have that IC remove.

It's possible that the TV broadcast isn't in true surround, and is only dolby encoded.
You can try going back to the component hookups, but I am not sure that will solve your issue.

Hi Laurel,

Overload in other unit protect error code. This will appear once the processor sense a malfunction either on the power supply or on the load (high chance is the output IC). DIY steps are as follow to determine where the fault is : 1. Allow the unit to cool down for an hour. Give proper ventilation and keep away all obstruction from the vent to have a sufficient air flow. 2. Disconnect one at a time the speakers, inputs, from the unit while powering it on.

If the unit back to normal again then you've confirmed that any of the above caused the error code. If #1 is the caused, you have to check also the exhaust fan(if installed), clean it as much as possible, replaced if faulty. If #2 is the caused (speaker) check the wire and speakers for short, (input) check the RCA cord for short or replaced if necessary.

If the above simple fix didn't cure the error code, you can try the next steps if you are an electronicsenthusiast. Now after removing the cover, you have to concentrate first on the power supply board. Look for bulged electrolytic capacitor. Leaky capacitor will affect the regulation of the supply and will trigger the error code. Look for dry joints. Check it also in the pre-amplifier stage, main output board where a big heat sink is located. Next disable the output amplifier stage by disconnecting the supply. If the unit come out, make some re-soldering on the board, spot the cold solder and dry joints and then try to connect again. If the error code appear again, high chance that your output IC is faulty but still to be confirmed. Using the disoldering pump and soldering iron pull-out the output IC from the board then try the unit. If the error code disappear, confirmed that your IC is faulty.After trying the abovesteps-by-steps guide and still the symptoms persist this is the time for you to send it to repair shop. Remember that your unit has a lot of parts and only some basic steps have done, leave the expert to troubleshoot the entire unit.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

hi,
do one thing
1. press and hold DIGITAL INPUT button on the remote( will display AUTO--PCM FIX--DTS FIX)
2. select AUTO among them. and the try
ok

F61 is the shorthand for Panasonic machines to mean protect mode. See the link below for a generic explanation of protector. Specifically, in your machine, either the regulator IC has failed or the output amp IC has failed. In any case, the repair will not be cheap. The output IC costs between $75-$125 depending upon the specific IC.

This sounds like a protect mode. Please see the following link for more information. Feel free to post any aditional questions that you may have.
