Max it is acting like the CRTC Board is not initializing. This is the
video controller PN5000929. Try reseating the board by first shutting
down the unit and removing the back panel. The large square panel
center right if you are looking at the unit from the back. It usually
has a hook attached to it. IF this unit has the ASC option there
should be a hand held keypad attached to the back of the unit. The
CRTC board should be about the third or fourth board down. It has a
VGA looking connector on the right side and a ribbon cable connector
on the left side of the board. The edges of the boards have small
flip out tabs. Flip these tabs towards the outer edge of the board
and firmly snap the it out of the socket that it is plugged into.
Reverse the procedure to snap it back in place. Check the other
connectors while you are back there to make sure nothing is loose.
