5 CD changer, model sa-ak600. What does code f61 indicate?

The f61 code is believed to be an amplifier circuit fault, but in reality it more often than not turns out to be a problem with a jammed up motor elsewhere(fan, cd changer motor, cassette motor). For me it was a jammed up cd changer. I simply disconnected the control for the changer and operation resumed as normal.

1. AFTER A FEW SECONDS MY SISTEM SHUT DOWN AND SHOW ME F61 ON THE SCREEN

I had the same problem. My unit would turn on, display F61, and turn off. I looked at the manual. It said if you see 'F61', check and correct the Speaker Cords connection. If this does not fix the problem, there is a Power Supply problem. Consult the dealer. Hope this helps.

i have vk70d and i have same problem .....your cooling fan not working ...chand it ...its work ....

Replace IC500 on power circuit board.
The board at the bottom with heat sink.
STK470-090 voltage regulator Sanyo original.

Try to power on the unit without the speakers connected. If it works normally without the error showing, then a speaker wire maybe shorted or a speaker defective. If the error F61 is still there, then most likely the Regulator IC is defective in the unit.

Hi, i had the same problem with a panasonic player, when you see the code F61 in the screen it is because the audio output IC is defective,change that and the set will work perfectly. hope it work.

Most likely the regulator IC is defective. Part # C5BA00000105.

i had the same problem with the error code f61.There are 2 fans,1 external and 1 internal and were both working but were very clogged up with dust thus working harder.Try cleaning them both it worked for me on the SA-HT 990 model
