What to do if my Panasonic SA-AKX52PH Stereo System turns on then displays F76?
- J
  Jorge BowmanJul 31, 2025
  If your Panasonic Stereo System turns on and then shows error F76, it could be due to a short circuit between pins 14 and 15, 15 and 16, or 16 and 17. Also, examine the cable wire connection between connector ZJ2007 (at Main P.C.B) and connector CN5802 (at SMPS P.C.B). Other potential causes include a faulty Voltage Regulator IC (IC2010), a faulty Switching Regulator IC (IC2011), PC5720 solder crack or dry joint, short circuit, open circuit.

  Kendra JamesAug 7, 2025
  If your Panasonic Stereo System isn't turning on, it could be due to a faulty AC cord or a loose connection. Other potential causes include a P5701 solder crack, dry joint, an open fuse (F1), PC5702/PC5799 solder crack, dry joint, short circuit, open circuit, or faulty ICs (IC5701 or IC5799).

  Alyssa MitchellAug 16, 2025
  If your Panasonic Stereo System works for a while after being turned on, but then displays F76, it might be due to improper contact between D5801 or D5802 and the heatsink. It is also possible that the set is triggering temperature protection.

What to do if my Panasonic SA-AKX52PH turns on then displays F61?
- J
  John EatonAug 23, 2025
  If your Panasonic Stereo System turns on and then displays F61, the cause may be a faulty speaker unit, loose connection, or a short. It could also be caused by defective D-Amp IC5000 or IC5200. You should also check the PWM output at pin 10 and 14 of D-Amp IC, check + VDD/SS supply at pin 4 & 20 of D-Amp IC, check pin 1 (OSC) & pin 23 (MODE) of D-Amp IC and check pattern crack and solderability.
