I had power up problem, after a while it eventually woke up but, the right half of the op-1 was unresponsive.
I tried for half an hour to get the com button to work, then made as factory reset and test.
test passed all but one single key, the paste key on the left side. All right side passed the test. Weird.
Upgraded the firmware to 225 successfully. I could play for a while before quit but I did not switch off, instead I let it on.
Came back after 6 hours. Com button as well as all right side of the OP1 was unresponsive again.
Switched off and on. Com unresponsive.
My guess the UI board is gone. Anyone had same issue? DSP Board has been recently replaced and all was working fine except for overload freezes but I did not think it was going to be this bad. It has been sit idle for a while since those freezes. Now I'm seriously worried I have to service it again.
