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.

IS it the amp fan failing? It could be something simpler and cheap.

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 '*****'. 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.

WE don't fix things, nor do we provide parts. We provide advice and answers and usually simple direction for where to look for answers, which are usually available somewhere on the Internet.

You can find the Service Manual (not necessarily for free) by web searching "Technics HD81 Service Manual". It will identify the fan part number. Then web search for THAT.

Only YOU know where you are so we can't point you to a repair tech. labor charges will vary. Once again, web search.

It doesn't want to work anymore!! There appears to be no power to the Disc Player, Cassette Deck or the Sound Processor? The Amplifier screen displays F61 Hope you can be of assistance Thank you


With my crystal ball I can see its a Technics 4 part Hifi micro system you have although the image is just too fuzzy for me to tell which model.!

Joking apart...Your power amp module has a blown channel. These are specific Technics modules and some for the 3/4/5 channel units are quite expensive UK £40-80 just for the module + fitting costs

No DIY fix I'm afraid

The F61 is essentially a "protect mode" mesage. A problem was detected and the unit shuts down. This translates into either the amp pac being defective ($approx $95 for part) or a defective regulator circuit (less $$). In either case, the repair is not the simplest to do. Check around for a Panasonic authorized service center and call to get an estimate. This is a relatively common fault, so you should be able to get a ballpark repair cost.
