I recently purchased a Virus B that is in exceptional condition (like new cosmetically and mechanically) but occasionally while playing the display will begin to fill up with "1"s and then "@" symbols "P"s and other random characters. When this happens the unit continues to play perfectly and I can even change patches and adjust settings but the display only shows garbage characters. All LEDs, functions, etc. continue to work perfectly. Even the LCD technically works perfectly as far as brightness and display of characters just not the right ones.
Should I do a reset? Should I reflash? Could this be capacitor/psu? Is this something more serious? Should I cry?
I'm capable at EE/soldering.
It is running 4.9 OS and right now I am controlling it from a Casio CTK-451 via MIDI on channel 1. I thought the "1"s may have been control from the Casio or some issue with the crappy Casio I am using currently. (Still could be, but I don't have any other 5 pin MIDI keyboards to test) TIA!
