My Yamaha PRS-293 will not play any of the E keys or the Bflat keys. I reset it once (power up while holding the highest note key) which fixed it once. Now it won't fix it. The MIDI plays all of the notes.

The key switches are scanned as a matrix. One of the matrix wires has broken or connector/cable is not making it... It will be a connection in common with the non-working keys.

Here is schematic:

On page 40 on the board labelled 61H-MK and the connector DMLCD-CN401 the connections to pins 11 and 12 with signal names N14 and N24 have become broken or disconnected before they get to the processor board.

Since these lines are NEAR an edge, the cable could be not quite in the connector at one end or the other. These two wires are what triggers the E and the A# key signals. There are TWO contacts per key as one closes first then the other... this is how they measure key velocity.

Kurzweil K250 music workstation seems to be locked up. When I power it up several of the lights come on and stay on. pressing any of the buttons has no effect. I have tried the three methods decribed in...

First thing is to check the power supply.

LIKELY you will find one of the voltages out of spec. You may need to check them with a scpe to verify they are pure DC.

At this age, electrolytic filter caps are very suspect and if power is dipping below the required the processor will continually reset or never run.
