F61 usually means the amp has detected a short or a severe microprocessor error.


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 another possible root cause forintermittent shutdown.

The ideal solution would be to swap out the entire cable for a longer one unless you have to...
It sounds like this isn't an option, so your next best choice is to get some extension speaker cable and cable crimp-on connectors or Wire cable connector blocks (see ebay URL with picture below ) from the wiring department at Radio Shack, Home Depot or your local hardware store. The crimp connectors are generally rubber shielded metal tubes that you insert the wires from the speaker and the extension speaker wire. You then squeeze the crimp-on connector with pliers to secure the wires in place.
IMPORTANT...During extension make sure the polarity (+ -) marekd with different color will continue from existing speaker cable.Otherwise you will loose the LOW NOTES -BASS

If you don't have any extra speaker wire on hand, you can pick some up at a reasonable price at Radio Shack or any hardware store. While there are many theories about what gauge speaker cable are best, you're likely starting with fairly thin wire coming from the back of the RCA home theater system, so crimping on a heavy gauge wire will do little to improve your signal quality. 18-guage speaker wire will likely do the trick in most cases. I would likely recommend a different solution if this were a component-based system with individually powered amps, but for an all-in-one system, 18-guage wire will be sufficient.
Crimp-on **** connectors come in a variety of sizes. Make sure the size you choose is appropriate for the wire you use to extend the length of your speaker cabling run. Here again, Radio Shack and the local hardware stores will sell the connectors you need for most of the common wire gauges.

The first thing to check is, all your connections to where you have it hooked up to, also check that the cable is in it's proper location, meaning your out put is leading to you other receiver in put, visa versa for the main receiver leading to the secondary receiver. If all else fails, leads to one thing, their is a possible short within One of the voice coils embedded into the speaker base. Which means, time for new speakers or check for warrantys or guarantees on the product. You could also check the companies website if you can't find a receipt. This is going off personal and past experience. All the best luck!

That would seem to indicate a major difference in loudness among the various channels, particularly the Center, where dialog usually appears.

According to the unidentified product's manual and speaker level setup procedures are the speakers about the same volume? Make it so.

Hi,here is my simple solution...
to listen your TV on your Panasonic Home Theater System
** you need to connect "Audio Output " RCA jacks or "Optic cable output" or "HDMI out "of your TV
** to "AUX input " or "TV" OR "Any input" of your receiver or "Optic Cable input" or "HDMI input"
** than just switch to respective mode on Panasonic Home Theater System RECEIVER corresponding your RCA or Optic or HDMI connection
.
There you go..Your TV sound is on the Panasonic Home Theater System Receiver..By this means whatever you watch on the TV (TV tuner, satellite , Xbox ..etc.) ,it's sound will come thru your stereo..

Hope this helps!..if more help requires pls let me know.

Any audio device that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input (except PHONO). Get a cable like the one described here: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10218&cs_id=1021804&p_id=665&seq=1&format=2
and connect it into any available analog input EXCEPT "Phono".

In your case that would be something like Aux or VCR Audio (In) (page 39).

Try a Search Engine. "panasonic repair (your location)". This is not a question for Experts.

Hi, Go to your local audio/video stores (radio shack , future shop, walmart) just to name a few.
Good luck.
