To clarify the repair the video board sets upright verticile that plugs onto the (main board) horizontal with locking tabs just lift up off clean pins with emery board spray socket with abrasive cleaner called (blue stuff )
I also checked for bad solder connections on the crt board and resoldered some connections on main board where the pins go in to the upright video board I hope this clarification is more complete
I am an engineer electronics tech for 27 years servicing
good luck people

If you can still see the video and some fine white lines running diagnally across the screen, it is very likely the picture tube itself which would likely be covered under warranty. If it is a solid green screen with no video, it could be a defective driver transistor or IC going to the picture tube.
