To Next PageTo Next PageWhat to do if my Panasonic Home Theater System powers on then shows F61 error?
If your Panasonic Home Theater System powers on and then displays an F61 error, it could be due to pins 14/15 shorting to pins 12/13. Check the Schematic Diagram of SMPS Circuit (Item 17.5) for terminal pin count on primary and secondary terminals.
Why does my Panasonic SA-XH20PH show F61 after working for a while?
If your Panasonic Home Theater System powers on, works for a while, and then shows an F61 error, it might be due to poor contact between D5706 and the heatsink. Refer to Fig. 1 in the SMPS P.C.B. to check this.
What to do if my Panasonic SA-XH20PH powers on then shows F76 error?
If your Panasonic Home Theater System powers on and then displays an F76 error, check the CN100 connection for looseness (lack of +23V) and inspect the cable connection between CN100 & H2016. Refer to Fig. 2. Main P.C.B. and the Schematic diagram of Main Circuit (Item 17.3). Other potential causes include no +6V voltage output at pin3 of IC106, an open L125, a faulty Q100 (no +5V voltage output at pin1,2,5 & 6), faulty Q107 & D114 (no +9V voltage), faulty IC107 (no +3.3V voltage output at pin1), or open K102, K105, K304 (+3.3V line going to Panel P.C.B. at CN203).
How to fix a Panasonic SA-XH20PH that won't power on?
If your Panasonic Home Theater System cannot power on, and the Standby LED is on, the cause might be a faulty IC2900 (no +12V output) or a faulty AC cord or loose connection. Refer to Fig. 1. SMPS P.C.B. and the Schematic Diagram of SMPS Circuit (Item 17.5). If the Standby LED is off or flickering, it could be a P5701 solder crack, dry joint, or an open F1 Fuse.
