Same problem, can we work together?
Hi KTM Rider
I've got the same panel with the same error, maybe this is a common failure for these and that's why they are hard to find.
I repair electronics for a living so I think I know what's wrong. There is a small memory IC right beside the CPU that I think is corrupted. I removed mine, copied it's contents to a brand new IC and soldered it onto the board but got the same fault. I think if I could get a hold of a working unit and read the memory IC on it I could write it to mine and yours and get them working again.
You mentioned that you had seen Prosine 2.0s for sale, if you can send me links I'll buy one of them and try my theory out, if it works on mine I can fix yours as well.
