Midibox16+ LCD weirdness

[Frank]

Hi guys,

I'm helping a friend to build a midibox16+ with 1664 firmware. I'm using the modified schemetic for this firmware and am experiencing a weird problem. If i use a particular brand LCD everything is okay. I have 2 other brands of LCD, and when i use them there are random values all over the place like pot jitter. All these LCDs work fine in my MF and midibox16e but why do only two of them cos pot jitter in a midibox16+?.

NE1 who can enlighten me please do. ;)

Peace

Frank
