Hi seanjenks,

and with the indulgence of the others...

To my understanding error code F61 is a "General Protection" used by Panasonic (and Technics). The general protection can actually refer to several things:
1. Power supply (as the others have indicated). This may be a defective regulator IC, a fault sensor transistor (over current) or even the fan simply not turning (which could be corrected with a can of compressed air and some lubrication);
2. Amplifier section - which could be the power pack IC or again simply some of its terminals/pins are no longer soldered properly to the PCB (printed circuit board). It is also possible that some of the connectors, terminals or other soldered joints are also just loose.

Perhaps what you can do is to isolate the supply to each of the components/sections and determine if the problem is caused by the load/consumer or by the power supply itself. Of course the logic board must still be connected for the display to function.

The above of course hinges on the assumption that you are familiar with electronic components and circuitry, the use of a DVM and a soldering iron. It would be of great help if you have access to a service manual or at least a schematic diagram with voltage readings. Should you not be comfortable with a DIY, then perhaps you need to seek the services of a qualified professional.

Hope this be of additional help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

F61 means 'power fault'

  • Unpluge the main power supply.
  • Then pluge it again and try. Also check the connection is good.
If no result on obove then:
  • Check out either audio power amp ic (IC 501) or power supply ic IC 502.

Thanks
Iqbal

You can't do much with this the AMP is dead. you need to replace it. it could cost alot.
else it can be like this

Generally a fault with either audio power amp ic (IC 501) or power supply ic IC 502.

As both said ICs get very got first remove bottom steel grill and with the power off and capacitors drained (shorted together with a low ohms resistor or leave unit powered down for a few hours) resolder the ICs legs if there are any signs of cracks aka dry solder joints.

    push the button on the stereo that says demo above it and hole this button in. unplug the power cable leave it unplugged then try to push the power button on the amp for 30 second without connecting the power source after that reconnect the power cable and see issue will be resolved.

On my 5 disc changer panasonic SA-PT950 there is a error displaying F61 then automatically shuts down. How can I reslove this issue?


F61 indicates a fault with the laser and the only solution is to replace it.

I've had a look at my usual supplier and can't find any reference to a replacement being available and on most occasions when they are available it isn't cost effective.

I have a panasonic dvd player ser no dd6ca001386r model number sa-ht990 when it turns on it comes up with fault code f61 what does this mean also i have just had a fan replaced but both fans are working


Did the fan replacement follow the onset of an F61, too? Or did the F61 come on after the 'repair'? If theformer, I'd ask the techto take another swing at it; if the latter, I'd ask the tech what he did to wake up the new problem.


Generally speaking, an amp protects itself from heat, shorts and overloads 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.

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...

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 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

Panasonic error code


Take the case off and clean out the fan, it worked for me, it was the protection circiut kicking in to prevent the amp from blowing.
