sorry wrong forum

have a 3300 with lightning strike. display lit but just garbage on it. mainline was pulled so batteries went completely dead while sourcing parts. adams now selling 3300 parts. wdpna board and canmb board replaced as well as main batteries replaced in tsu. all idiot lights and power supplies now in correct state ,but display is dead. not even a dot. did I get a bad MB or am I missing something. I am assuming that MB
was flashed with software. I would expect the display to do something even if software not installed.

Try posting in the right area, might get some answers.
