To Next PageTo Next PageWhat to do if my Panasonic SA-BT230P Speaker System turns on then shows F76?
If your Panasonic Speaker System turns on and then displays 'F76', check the connection between the Power P.C.B (CN2916 & CN2917) and the SMPS P.C.B (CN5802 & CN5803).
Why does my Panasonic Speaker System work for a while then show F76?
If your Panasonic Speaker System can turn on and works normally for a while before displaying 'F76', it might be due to improper contact between D5802 and the heatsink, or the set might be triggering temperature protection.
