Hi,
F61 is an error code that shows amplifier output chip is defective and need to be replaced in Panasonic SC-AK640 unit.
Amplifier output chip replacement requires soldering work and local repair shop will do this job as it is not user level repair.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

F61 is an Error Code,more specifically a Fault in the Power Amp,the Stereo will need to be sent into Panasonic for Repairs.

Hardware store. Ask for lamp gord wire 16 or 18 AWG.
good and inexpensive

I suggest you Google Panasonic on your computer and pose your problem to them. They will tell you what the code means and what needs to be done about it to make the stereo work properly.

That message means the audio amplifier IC´s are damaged

Change the audio amplifier IC are damaged that´s the mean of that code

F61 Power Amp IC output abnormal
Upon power on,
PCONT=HIGH,
DCDET=L after checking
LSI.
For power.
Press [STOP] on main unit for
next error.

Usually the problem here is the output amp pac(s). Without takeing a few measurements, I can't tell you which ones. Also, can you please check the model number, I can't find a listing for the one you posted.
Thanks,
Dan
