No sound,Data slider doesn't work etc CPU card?

[mg73]

My EIII all of the sudden has no output and DATA slider is not working.
It's not the Relay or 5532 it's more of a CPU card problem, I think.

Data slider and Keyboard works fine during tests but Data slider doesn't work when for example going thru banks, presets etc

Any ideas?

Hi,

I'm by no means an expert, but if it were my unit I would try reseating the cards in the cage, check the power supply cable that connects to the vertically mounted motherboard and the ribbon cable that links the control panel to one of the cards in the cage.

Just my 1 cent (I won't even say it's worth two!)
