That's probably not the flyback issue.  More than likely it's either the
monitor cable, driver board, or tube.  It might even be the video card RGB

I rescued a 233 Bondi with exactly the same symptoms.  That _is_ the
PAV/flyback issue most likely.  You can confirm that by taking off the
bottom cover and removing the monitor cable and plugging an external
monitor into it.  It should come right up if it's the PAV issue.
I don't know if you can switch the 333 "sled" into the workign 233 case. 
I doubt it though.
If you want to get rid of one of the three I'll be happy to take the
red-dot one off your hands for cost of shipping.
