: : I think I fried the LCD board on my QS8 by plugging
: : in the cable the wrong way. The display lights up,
: : but the synth doesn't play. I've ordered another board,
: : but want to make sure I don't fry it too. Is it pin 1 (red edge of flat cable) toward the top of the main board? Any schematics, or advice?
: The schematics can be downloaded from our Software Page. Click on SOFTWARE in the left column.
: While you're there, get the Service Manual as well, you may find it useful.
though schematics are for QS8.1, not QS8. The former
has a 16 pin flat cable to the LCD, and is supplied with -5 volts, I don't find any -5 volts going to
the QS8 LCD. Either it isn't there, or I burnt a
trace or something. The QS8 flat cable has 14 pins.
Just to clarify, the QS8 runs fine
as long as the LCD card isn't plugged in.
Service manual is a help, thanks again!
