    Hey everyone,

    I just picked up an Earthshaker and I’m having a problem with the lower display. The top display works fine but the lower display is not showing anything. I checked out http://techniek.flipperwinkel.nl/wms11/index3.htm#display and noticed my negative voltage is around 128 volts and my positive is around 103 volts. I’ve also flipped my ribbon cable (same problem when flipped) and checked the two fuses for the 100+ and 100- (they are fine). So far the only thing I’ve noticed is my negative volts is out of spec. It should be around 105 and it’s at 128. Could that cause the lower display to not work? Any help is appreciated.

    You proabably have a bad glass. Never seen an electronic component other than glass on these boards that cause one display to be completely dead.

    That’s what I was thinking

    Can you post a picture of the display driver board behind the glass?
