I just had the same problem on my technics amplifier Talked to support, and they said that it probably needed a new power amp, ic501 (I think). Searched the web and was told to check the cooling fan on the back of the unit. It wasn't spinning. There was another small fan inside that would spin for 10 seconds or so, and would stop. After pressing the power button, I spun the fan with my finger (as best as i could) and the unit powered on, until I stopped spinning. I took it out, cleaned it, and the unit worked fine. A new power amp unit is $95, this cost me nothing, but even if I needed a new fan, it has to be less than $5.

F61 faultcode.
Add a capacitor of 10nF to the internal fan.
Remove the fan, open the fan casing and add a capacitor across the motor connections.
This will help and solves a lot of F61 fault codes to a big variety of technics sets.

I JUST UNPLUGED ALL THE POWER SUB/RECEIVER. THEN PLUGED IN THE RECEIVER THEN THE SUB POWER. TURNED THE UNIT ON AND OFF IT SHOULD WORK.

I had the same code error on my unit. I turned off the power, no luck. Unplugged the unit from the serger box, no luck. Hooked up the speakers according to the manual, no luck (I had them hooked up to what sounded better to us.) Then I unplugged the system from the power serger box and directly into the wall. No luck again! So, getting frustrated from squeezing behind the fish tank to get to the surrround sound wiring, I held down the power button on the main unit. It clicked off and on about 12 times while the whole time I was holding down the power button. It seemed to reset the unit. I had to turn it off and on again as I cound not control the volume. Then everything returned to normal.

F61 for Sa-eh770 = Power amplifier output error or power supply circuit error.
Supply voltage for IC501 (Power Amplifier).
Approx. +60.0V dc at pins 3 & 20.
Approx. -60.0V dc at pins 4 & 21.
A qualified engineer may check the above voltages.
