I had the same problem for at least a year or so with my matrix 6. when it came to me half of the patches were normal the other half were the weird characters thing. the dude i got it from said he thought it was "some dead voice chips" i told him he was an idiot and to stick to playing guitars, then i bought it... (im dumb too i guess). one thing, mine sometimes would just be dead for a month then one day it would decide to power up and have crazy ass characters allover, or it would just power up fine to factory presets. after continuous tinkering for a year or so i have got it to power up every time into a hard reset/calibration mode, im not sure why it just jumps to calibration. In other words i cant save any patches i make unless i involve my librarian. Also i have no idea what i did to get it this far, because at this point ive tried every little possible thing to get it working right, voltages, battery, traces, wires, reseating, cleaning and psycho therapy...

anyway its interesting to hear im not alone, hope you guys figure this out, i would love to get mine working perfectly.

Does it play OK, and you can still adjust parameters etc, only the display is problematic?

I just joined the group yesterday. If you can point me to the previous discussion I'd appreciate it. The problem is it sometimes powers on without a display, other times it's limited to 7 or so characters and other times the whole diplay fills up with random characters than change when I press the keys. It seems too erratic to be a self-test mode.
