    My stereo turned off about 3 days ago, and when I hit the power button it won't turn on, it just displays F61. Do I just have the fan replaced and it will work? Is that expensive?

Hello i have a panasonic SA-AK78 and show F61 and don't turnd on.


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.

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...

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.

SA-HT680 F61 Error


Typically the F61 error is a protection error indicating that there is a problem with the output amplifier section. The failiing part is usually IC501 (part number RSN311W64D) which costs about $95. Have this unit checked as there are other possibilities.

F61 error


I had the same problem, and I had to replace the fan on the unit. The fan would not turn on at all, so the computer would tell the unit to turn itself off. After the fan was replaced (which is relatively simple) it works like new.
