In this case there are no plugs, but that doesn't mean some connections cannot fail. I can see taking that whole thing apart is going to make a frightful mess. There are sets of keys and the sets I have off now are not all the same. I can't just throw them in a box, I'll have to lay them out in order. then I can really get a look at the board. There are not 88 wires going to the other part of the thing so they must be scanned/multiplexed somehow. There are probably pulses on them. Somehow I could determine what wires are what, and find maybe the pulses are missing on the non-working keys. If that's the case then it is not thw rubber thingie at all. |

I've bought several, because I needed MIDI out for a project. I never paid more than $20 at a yard sale and usually $10 was enough. They just aren't good enough for any serious musician, and as a toy people get tired of them fast and they collect dust. Trash it and buy one that works. |
| jurb6006@gmail.com: Jan 20 09:33AM -0800 Thanks. I had forgotten that trick. For so long now everything I touched had integrated PLL in the tuner or front end. Unfortunately, if there is leakage on the Vt line it is curtains for this thing. No way I am changing those diodes and going through the alignment. Not sure I could scare up the right equipment even if I wanted to. |
