    JVC1.jpg JVC 2.jpg JVC 3.jpg Hi,

    Just looking for some advice regarding the JVC RC-717 LB (my first box) please.

    Likely to be a very obvious answer however, I am struggling to see where the pictured cable coming from the speaker goes too. I have opened the machine for a clean and when putting back together, the output is all working as it should even though there is a lose cable there.

    If anyone could guide me to where this need to connect to, I would be most grateful.

    Also my next job on the list is to remove the board and change the belts however, despite what seems to be all screws removed, the board didn't want to go anywhere. Any tips on how to remove or if I am missing something.

    Many thanks in advance.

    I'm surprised to see so many spade connectors, I can see them being used on speakers but the rest seems odd. Did you download the manual?

    I don't see the spade connectors on the green board but the manual is a little hard to see. There is some differences between the "L" and the "LB" Model, maybe it's not used in yours.

    I think it should be attached to the back of the plate shown in fig.2...and a ground wire

    Hi, thanks very much for this.
    I did download a manual but as you said it wasn't too clear.
    i will check the back panel again and see if there is anything there.
    Thanks for your help, much appreciated!
