How to solve pinchroll error invalid right pos

It's a Chinese made Roland and no service information is available as when a fault is found the main board is replaced, eliminating the need for service information.
I would check that it is a stereo out jack and not mono. If it is a stereo out, check that both input phonos work. If they do, replace the faulty socket or damaged pcboard.

I suggest you contact /Roland directly. Here is the link-

if its less than five years old then you maybe able to order it right from roland , older than that you can always ask them but you might be out of luck , a friend of mine had a problem with his keyboards display too and it turns out it had a external display monitor output on the back, ive rigged him up a small 4 inch tv that plugs right into it and now he can select all his functions using that . works

I would suggest updating to the latest software first to see if that solves it.

Roland Juno gi program error problem

I have the same problem with my module and I can\'t find the solution anyware for the thing.Closest solution that I could find is something about Roland power adapter.Apparently module won\'t work with any adapter with the same voltage,only Roland or Boss B.R.A. adapters works.I have original Roland adapter and still shows an Analog test error.


Have you find the solution in meantime by any chance?

do you want to sell the old main board?

If you have the version 1 cable you need to download a driver. The details are at this link:http://www.cme-pro.com/en/news-detail.php?news_id=105

The only thing to try is a "factory reset" procedure. If this doesn't work, then it has to go to a repair shop.
