Hi,
Who knows more about how those 2*16 character displays work ?
If they go bad, what could be wrong ?
Displays like this one:
edit: -- non working link to pic remived, I guess we all know how a QV looks like --
More specific, the characters on exactly the right half of the display of my old Alesis Quadraverb-plus
have gone. The orange lighting is still complete.
So when we number the characters from left to right, top to bottom,
the characters 9-16 & 25-32 are absent (or very very faint when looking at an angle from above).
The left half works fine.
These display-modules consist of the screen themselves and a PCB behind it with some additional electronics.
When powering on without the connection from main-to-display-module removed I do see
several characters in the righthand side of the display, which gives me the impression that the screen itself is probably still OK.
Anyone experience with repairing/replacing such displays ?
I have schematics etc, but don't want to complicate this post further -
so for now I'm curious to what could go wrong in general and what's
most often the story for displays gone bad.
Thanks,
Peter
