HELP please! Cent 4, blank screen

[Brian FRF]

Cent 4 controller. Was running fine earlier today, had to go do some other things for a couple hours, left it on (on, not e-stopped). Came back controller was locked up. Ive had it lockup before, so just turned it off (usually if I dont e-stop it it doesnt lock up). Turned back on, was doing ram test 1010 1111111111, real large font if it matters. Turned back off and back on, (had that clear it up before) Nothing, blank screen. Checked connections and voltage to the little battery back there, right at 3.6v.

Ill keep tinkering, but really need this machine back up tonight!

Awesome, thanks!

FWIW, turned it off, let it sit for a couple hours, and all was fine. Thinking it got hot. I did find out the fans for the boards that are mounted to the door. Those fans are sucking rather than blowing across the boards, so thinking Ill switch the wiring on those, should help.
