sanyo m7500f earth problems

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

The speakers should be grounded on the board and not on the trims. The ground wire probably terminates on the board near where the spk out wires attach. The L/R grounds might attach to the board separately or they might connect to each other. In other words:

board ground --> speaker 1 --> speaker 2.

It seems this is a very rare model. Finding someone else with one that is apart to look will be very hard.

so looking from the back the right speaker - black gose all the way to left - then another black gose to earth remember i am looking from the back

aha this is just what i want thankyou sooooooo much for the pic's nz boom !! I'll do this today and get back to ya on the results again thanks

right redone all the wires and now i find it's going but still the left side speaker is out but only on stereo/mono on wide it's great what is going on???I've done the switch i removed it and clean it all up it was quite green in places but it's like new now so it can't be that can it??? Sanyo's just do my head in they really do
