I have a panasonic model # SA-AK600 whose volume keeps fading in and out how do I fix this

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.

if you get a tv repair man he can fix and order the part that is the problem it is a twelve pin plug that needs specilist tools to remove. The part is an amplifier chip, common problem with the sa-ak600.

sounds like the laser is no longer working. Call partstore at www.partstore.com and let them know what model number you have and that you are looking for a replacement laser for the unit. Replacement is for the mechanically inclined or a technician. The part is static sensitive so I recommend taking the unit to a repair center.

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.
