By jumping around, I mean just one patch, say "Mike's V Kit" For example - is on the screen but it is kinda "blipping and shaking " all over the place. I have tried it with no triggers plugged in at all, a couple different outlets, and always the same result. I did try the adjusting the contrast already, and that simply did what it is supposed to do- it changed how bright/dark the screen was, but it was still littering all over the place.
I hooked it up to my zendrum, and it seemed to "play"fine- I just can't really make any modifications or adjustments anymore as I really can't read the screen!
David- I have a call in to a local authorized Roland repair technician- they called me back but I wasn't t available so I will touch base with them tomorrow- I'm hoping they are a decent price, as there aren't too many authorized dealers in my location. I would hate to see the 20 just go to waste..
I actually dug up some info that this is a bit of a common problem in the earlier runs of the TD-20, not too sure how accurate that is though, but mine would certainly qualify as being from the early production runs.....
