[sdiy] Oberheim OBXa keyboard help

[Tom Wiltshire]

Another possibility (one I came across on a J-wire Pro-One) is that the 
keyboard connector is dodgy. The Pro-One uses a DIL header on a piece 
of ribbon cable to connect the keyboard to the main PCB, and this was 
corroded. This produced various dead keys, and a dead section at the 
top of the keyboard. Obviously the key fact here is that the dead keys 
form some sort of pattern - every 6th key, every 8th key, all the Db's, 
etc. If there is more than one problem (more than one dodgy pin on the 
connector) this can be hard to identify. But the good news is that it's 
a dead cheap fix.

Hope this helps,
Tom
