In Reply to: About Replacing QS LCD panel posted by wavewizard on April 21, 2006 at 12:15:12:
It's not going to help much, but that's the classic symptom of having the wrong wires going to the wrong places. (Or possibly a dead new display, but I'd go for the wires first.)
: Hello, years ago in this message board paul wrote how to replace QS LCD panel.
: I've constructed a cable, crossed the pins etc. Got the contrast and backlight working, but my synth (qs7) goes silent/hisses when the new display is connected. The display shows the default HD44780 all solid bars across the top line for not initializing. If I plug in the old dead display, everything is fine (execpt displaying characters)
: Anyone here know how to solve this. Please help
