Had alot of problems with my sanyo 7500 mini when i got it, the speaker wire's were not connected on the board!!! they would have been soldered on well i found the positives because the board says spk!!! but I can't find the earth. One speaker is earthed to the box front panel which is metal where would the other one go?? would that be on the board somewhere or could i get away with it being earthed with the other one!!! I'm sure it came from the board as the wire is bent towards the board or where else can i earth it too!!! I can't find out anything on google so this is my last chance!! thanks
