Screen Jumps

[Perfect Day]

Hi , anybody else here experiencing screen jumps ? Ive been getting them since Ive had my A6 . Fireing it up in debug mode and going through the procedure seems to work , but takes a long time . After a while the jumps come back to , Mine seems to jump to Env 2 or the post filter page a lot, but at the moment is jumping to the voice output page :S . Does anybody know what causes this and maybe a way to stop it ? I had the same thing with my ion . Thanks

open your Andy and first of all try to reseat the flat-ribbon cables.
Often it works.

Thanks , had it open once , all the cables should be ok , but ill give it a go . When the cables werent seated properly I had problems with the pot values . But Ive had jumpy screens since, and before it was opened and the cables checked . May take a while to get round to that though , Not much room here
Thanks again

Sounds like jittery pots that make the CPU falsely assume that they have been tweaked, hence the screen jumps. A common problem. Most often caused by dust and/or the pot not being used alot. Try hunting down the offending pot, pull off its cap and thorougly clean away the dust/dirt underneath. Also, moving the pot fully clockwise and back many times can make it stop jittering.

If this all doesn't help, the pot has to be replaced.

Good News !!! Tweaked every pot in the offending module fully left to right a few times and screen jumps have gone !!!! Good stuff

...and always tweak all the A6 pots at times when you are not that creative
Andy doesn't like at all to be without pot operation for a long period, and doing this once per month will normally make this issue disappear forever.

Also note that mostly it's not a cause of dust - the pots inner contacts just become oxidized, and just tweaking the pots cleans them very well.
