Re: sega monitor adjustment help

Mickey,

A bad custom chip on the main deflection board can cause this symptom. Not
saying that this is what's happening in your case, but I had the exact same
problem many years ago and it was because of the custom chip (swapping in a
known good one made the problem go away).

Subject: VECTOR: sega monitor adjustment help
I have a sega star trek in a convert-a-cab.
I have a nice bright picture, but it does have one issue.  If the monitor 
has to draw a box, it is the most evident,  instead of being a square, its 
more like a parallelgram.  The lower part of the square is shifted to the 
right a bit.  I am used to adjusting atari games, but on sega I really don't 
know what to do to fix this.  I have recapped the monitor with no 
improvement.
Another example that shows the problem is a high score list.  each score 
starting at the top and going down is shifted a bit to the right.
In star trek its not very noticable, but switching to eliminator or zektor 
its very noticeable.
I will say that all the vectors are connected very well and the convergence 
and focus are also very good.
thanks in advance for any help,
mickey
