Originally posted by leeboy: YES, this is hardware issue...Take it from an ex-IBM service man...DO NOT use a voltmeter anywhere on those boards! Todays typical VOM meters will load the ciruit and could cause blown components(if you don't short something out yourself anyways)..AND watch out for ESD (static) if you touch one of those components with you finger or a tool with a static discharge on it...BAM! Blown circuit.
Those circuits run on very low voltage and current. An osciliscope would be needed to work on the circuits and if you saw the schematic you would be amazed at how complex it is. Not the type of work for an owner.
If I were working on this issue, I would carefully and delicatly take an INSULATED tool (wood, plastic) and gently push/move/press/prod etc very slowly around on the circuitry. WHILE continuously playing. Make it fail.
Also, maybe it is heat/cold related. Now that you have the cover off...things may have changed on temp.
Also, you could WITH POWEE OFF, spray the components with freon to cool the circuits, then power on & test. Alsoa hair dryer used carefuly can suppy the opposite help.
If you find a place where you can make it fail...I would get Ketron to fix it. I would not tell them I had it apart!
You could say..in this or that area of the keyboard (covers on) when I vibrate it...it fails.
Quite honestly, I think you would be better off on a new board under warranty to return it for service OR better yet make them give you a new one!
If you scrw up here working on it...the results could be very epensive.
Lee S. Leeboy, There are no Ketron keyboards going back to the factory, Ketron don't do that. Your dealer will need to fix it and I don't care how far you are from him, he sold it you he should get it fixed.
