Question about Audio Players & Recorders
HI there do you have a circuit board wiring diagram for the MK 2061 Electronic Keyboard? I have lost sound, have taken the back off and found a white wire has come off from somewhere but unsure where to solder back on. Thanks :)

SOURCE: Speakers Cutting Out
I posted this solution on FixYa to help someone who had the same problem, or at least a similar problem. If you remove the slotted panel underneath the bottom of the receiver, you can gain access to the underside of the main circuit board. There are 3 relay units there, they are blue boxes that can be seen if you shine a torch down through the top. I found the solder joints on these relays looked as though they had broken away from the board, there appeared to be a dark ring around the pin of the relay. I re-soldered 4 of these connections, and, so far, that seems to have done the trick. Time will tell. These relay units connect and disconnect the speakers. There is one other relay that is mounted on a seperate board above the main board, that I can't access easily. If this one is also faulty, I will be un-able to fix it, as it would involve removing the entire guts of the receiver. If any of your technical team disagree with my remedy, or can offer any other solution, that would be appreciated. Thanks.

I think you should buy a video sender. It will take audio from your audio console and send wireless to a free channel to any free TV channel. No cables!
Here's one on ebay:
