That is a protection indication. This means that the output amplifier section has a problem that was detected and a shutdown occurred to prevent further damage. I don't have a listing for your model, so I can't provide you with too many details, but look for a large black IC attached to a heatsink. That should be the output amp pac. If there is not one, there should be 4 3-legged parts (transistors) and one or more of those may have failed. I have also seen cases where a voltage regulator that supplies the driver circuits has had bad connections thereby shutting down the driver circuit.

Keep us posted.

My technics separates will not turn on and it keeps saying F61 and aint got a clue wat that means


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.

F61 usually means the amp has detected a short or a severe microprocessor error. I'd suspoect something along the lines of the former.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.

Keeps showing F61


Panasonic error code F61 is for an output /power problem. Most likely it will need the output ic replaced. But check that the fan(s) are running a bad or stopped fan will also cause F61. Replacing the IC is best left to a technician and Panasonic is the only supplier that I know has the part.
