Remove cover and make sure the fan is ok...not clogged. Also, you could have a bad audio output IC or cold solder joints on the output IC. Use a volt meter to see if voltage is present on the speaker lines. If it is then your output IC is bad.

F61 errors on SA-AK249 panasonic stereo


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 a root cause for intermittent shutdown.

- Is your system playing in spite of this error?

Assuming that this is the model complete with "receiver" and speakers+sub and you use these and the original connections. You could try and measure your ohm level on each speaker to control if there is a bad/blown speaker. The Ohm level should be the same on each speaker - roughly.
- Hope this will get you somewhere!

Hi,
f61 is a protection code. it means theres is a fault with audio output ic, usually there is dc on one of the speaker output rails, replacing the audio output ic will usually cure this but check speakers and leads for shorts before reconnecting to the unit.


Thank You

Humming through speakes when on auxillary


Most humming in North America is either 60Hz or a harmonic of 60Hz. The number one cause of humming is a poor common. On co-axial cables this is the outside connection where as the signal is the male post in the centre. Corrosion, oxidation, poor contact are all possible things to check.

Panasonic sa-ht995 will not work ...... when turned on it says hello.......then f61 then turns off again how do i fix this problem?


F61 in the user manual says , check your speaker connections if ok then see your dealer, the reason f61 comes up is a amplifier fault , most likely a blown audio amplifier ic is faulty, and needs replaceing by a compenent electronic technician.

F61 error


If memory serves me correctly, the F61 message is teh shorthand for protect mode. There is a problem with the output section that is being detected. The unit shuts down to prevent additional damage to either the amp section or the speakers. I'll look up your specific model for more details. In the meantime, check the speaker wires to be sure that they are not frayed and crossed.

Panasonic stereo SA-PM28 displays fault code F61 then switches off


Hi dearnley1

The error code your unit is presenting relates to either a speaker cabling fault or a fault speaker. Sometimes, it is neither, and may be a fault inside the unit. Needless to say the unit is in protection moe to prevent more damage occurring. Check you speaker wiring for any short circuits or frayed wires. If all appears to be ok, disconnect the wires from the unit and see if it turns on and stays on then. If it still presents f61 with speakers and cable disconnected, then I am afraid that you may need to take the unit to a Kenwood service center near to you for an inspection . Good luck
