Mine is a known problem. There is a 3-position sound switch, #1 is TV sound, #2 is off, #3 is radio sound. Someone put all the speaker wires on the TV terminals, now the front speakers do not work after sitting last year.
It's gonna be a tedious job identifying all the speaker wires, 14 in all. Then correctly attaching them to the correct terminals-if they even work on the radio terminals.
