In this video I rip into my 4 day old $700 Yamaha DGX-640 to move the phono jack from the back to the front of the keyboard. So much for my 3 year warranty :( But it had to be done because it was not accessible in the back plus having the wire draped over the keys or roped between your legs was annoying. Another annoying feature was the easel being mounted at the very back of this large keyboard deck. It was so far away we couldn’t make out smaller notes or markings. So at the beginning of the video I show my swing away easel hack that fixed this issue nicely and was quite easy to make. (After the video is a bunch of hi-res photos)

  1. […] Check out this brand new Yamaha keyboard. The fact that we’re seeing the guts means that [Todd Harrison] can kiss his warranty goodbye. But by now you should know that he doesn’t look to others when something goes wrong with his electronics. This time around he’s not repairing anything. He didn’t like having to plug in headphones on the rear of the keyboard. He cracked it open and relocated the headphone jack to a more convenient location. […]

    The under 1000 dollar pianos have the jack on the rear ’cause it’s on the amplifier board. The higher grades jumper it off to the left end on the skirt. You should mount it there, with a hot tool to melt dividers and epoxy it in place in a neat hole built in. There may be room enough already. Or use a hole mount jack with the cut-outs. Build it in, no wires to break in moving. Come to think of it Yamaha uses a pair of jacks on a metal plate under the left end in a hole cut in the “wood” bottom facing down.

    @echodelta, I might just do that. Thanks. For now I wanted to be able to undo my hack just incase I had a warrenty issue.

    Why would you Void your warranty if you didnt leave the jack internal on the front? You should have just used a headphone extension cable into a project box on the outside, leaving the original plug and warranty intact. To void warranty you should have made the mod as unassuming as possible. IE, leave the jack inside on the front.

    @Bryan, It is not just a jack it is also a switch. When you plug in a phono plug the internals of the phono jack also disconnect the large speakers on the keyboard. So you see, you have to move the phono jack/switch to a new location. Just jacking in an extension would leave the speakers on the keyboard disabled until you unplug the extension. We sometimes want to play with headsets and sometimes with out.
