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.

My panasonic sa ht930 volume when you give me presents on the screen and I f6 1 off


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...

I WHAT IS FULT OF F61 IN SA-AK177


HELLO
F61 means a protection code which normally means there is a fault with the audio output IC. Check all your cables for shorts etc, and try hooking it back up. If the error is still there you'll have to put it in for service.
ALL THE BEST!

F61 is a problem with the output amplifier pac. It is the equivalent of "protect" mode. The output pac needs to be replaced. I'll look up the part number for you.
