Hey all,

I have been given a roland w-30 to fix by my band (I am the tech in the band).

I switch it on and get nothing, apparently the lights in it should light up when power is applied, but I get nothing.

I have a system disk, but this does nothing either.

I thought it may be a problem with the LCD but this would not affect all of the lights would it?

I have tried to alter the contrast and this has no effect.

I have power across the input, and again after the power switch, but I need a schematic to look any further.

Any help would be greatfully recieved.

Mark
