To Next PageTo Next PageWhy my Panasonic Home Theater System cannot turn ON?
If your Panasonic Home Theater System won't turn on, it could be due to a faulty AC cord or a loose connection. In this case, refer to SMPS P.C.B. Fig. 1. Other possible causes include a solder crack or dry joint at P5701, an open F1 fuse, solder cracks, dry joints, short circuits, or open circuits at PC5702/PC5799, or a faulty IC5701 or IC5799.
What to do if my Panasonic Home Theater System turns on then displays F76?
If your Panasonic Home Theater System turns on and then displays "F76", there might be a short circuit between various pins (14 and 16, 15 and 16, or 16 and 17). Also, check the connection between the Power P.C.B (CN2916 & CN2917) and SMPS P.C.B (CN5802 & CN5803) referring to Power P.C.B. Fig. 2. Other potential causes include an open L2902 (resulting in no input to IC2901), a faulty IC2901 (no output voltage at pin 10 & 11), faulty Q2902 & Q2903 (Regulator), an open L2907 (no DC +12v), an open L2908 (no DC+5v), or issues with the cable connection between the D-Amp P.C.B. (CN5400) and SMPS P.C.B. referring to D-Amp P.C.B. Fig. 3. Furthermore, check for solder cracks, dry joints, short circuits, or open circuits in PC5720, referring to SMPS P.C.B. Fig. 1.
What to do if Panasonic SA-BTT350P Home Theater System turns on, works, and then displays F76?
If your Panasonic Home Theater System turns on, works normally for a while, and then displays "F76", it might be due to improper contact between D5802 and the heatsink or the set triggering temperature protection.
