Hi! I buyed a Stereo Panasonix SA-CH74 Model 14 years ago. It was a great thing. But I noticed a problem with it. After one or two years F61 error begun appearing on display and stereo switched off....


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 'nekkid'. 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 for intermittent shutdown.

I HAVE A PANASONIC CD STEREO SYSTEM AND THE DISPLAY SHOW: F61; WHATS THE MEANING???


F61 is an error code.
It will automatically shuts down your unit.
This is very common on your unit.

Try to checked if the fan is working or not.
I have repaired some unit before, this is the caused why f61 appeared.
The symptom is shutting down the unit after a few minute.
If the fan is not working it will shuts off automatically to avoid further damaged to your output I.C. from overheating.

If confirmed that the fan is working then I've suspect that your output I.C. is shorted.
This is quit technical and need to send to repair shop to isolate the faulty parts.
The output IC of your unit is RSN series and quite expensive.

Pls rate my help.

Thaks for using fixya...

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

After hooking up stereo system in the house we turned it on the console shut off and displayed a code of F-61 unable to locate manual need assistaance to get my music going


Hey there,

Let me guess. You have a Panasonic SA series receiver.

I hate to say this, but the music is going to be delayed. You are not alone with the dread 'f61' error. It occurs for a lot of reasons. The cause is a burned out IC.

But it's fixable. Learn more:

I did a little more searching on the causes (and solution) of your 'F61' error.

According to the manual, it is a fault with AC power or the speakers. (Not!!)

According to Panasonic Customer Support (and I quote):

"Thank you for your email enquiry.

To clarify, the F61 that has been displayed is a self-diagnostic fault
code, requiring attention by a qualified engineer. This is not an inherent
fault with the product but a guide for the engineer to know where, within
the product, he should seek the cause of the problem.

We suggest that the product is submitted to either your retailer or to an
authorised service agent for attention. Those in your local area can be
found through our website;"


(This is a copy of the e-mail response, the spelling errors are theirs, not mine.)

Thereal cause is heat. There is an Integrated Circuit (STK470-050) thathas become notorious for failing throughout the Panasonic SA Series.

WhilePanasonic's suggestion to take it to a qualified dealership does meritconsideration, they may charge you morethan it would cost to replace.

Ifyou were inclined to fix it yourself,. If you also have experience with a soldering gun andpatience, you can fix it yourself for under Forty dollars.

Belowis a link to a discussion page devoted to 'F61' Errors. Some of themgot tired of waiting and found a way to fix it themselves.

Click here for the Stereo411 site.
What you're looking for is a post by 'ragtop67gto'.
It's an excellent step by step of the fix. The decisionto fix it will depend on your comfort level with a soldering gun. Butit will be an informed decision.

Click here for a source to purchase the IC chip.

Bottom Line:
  • If you know your way around the interior of a stereo, you can fix it yourself. (90% effective)
  • Bring it to an authorized service agent (90% effective)
  • Other than that, it's history.
Just trying to be thorough. If you need further info let me know. (click the ASK button)

Even though the fix is involved, it's still a fix, don't forget to Rate this response.
Mike

(Personal Note: If you thought about fixing it yourself, even for a second; Go for it, little risk, high reward.)

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

regards
Graeme
