Last week I had to relocate our console which involved turning it off and unplugging the power supply. Now it has developed a behavior that makes selecting anything from the menu impossible. If it were a video switcher I would describe it as being stuck in bulb test.
Example: I select the 'set-up' key. The set-up menu appears but the options curser cycles through the options. I cannot directly enter an option number; it goes to whatever option is highlighted when I press enter.
If I select 'stage' / 'channel' the blue box in the top right of the display rapidly cycles through all of the channels.
Left setting for several minutes and random functions activate and other numeric displays cycle.
HELP!
