Video Issue with Color Classic

[Crudus]

Hello,

I've gotten my hands on a color classic and I've been working for a while at trying to get the thing to work. When I flip the switch on the back, then start it up using the keyboard I get a green light, no startup chime, and a blank white screen with no cursor. I've recapped the board, and I've got two analog boards to swap (I've tried both) which leads me to believe the problem entirely logic board related.

Any ideas?

Thank you

Did you fix this ? I have the same problem with a recapped analog board and have tried to two working logic boards. I get a bong on startup and I know the logicbaords work ok in another CC.
