Title: Squished picture problem.

If adjusting vertical size/height and the 50/60 hz pot doesn't help then your monitor probably needs a capkit.

Yeah figured it might be that.  A couple more things I only have 5 video wires running to the board R,G,B, Hsync, and Ground should I have a Vsync or is it carried on one of the other wires?

One more question.  Do I have a vertical size problem or horizontal size problem? The screen in horizontal and there are 2-3" gaps at the top and bottom.

Monitor problems are described just like the way a normal tv set would be watched so you have a vertical problem if the top/bottom are affected.

Your monitor's video/sync input is wired correctly. Not every monitor nor gameboard needs the vertical sync hooked up.

So i guess I need to do the cap kit then I was looking through bob roberts site and he has cap kits of K7000's and mine is a k7191 so is that the kit I should get?

Also I was reading around about vertical output transistors going bad and causing similar problems to what I have should I replace those as well?

Oh and thanks for the help guys (guys = Ken)

I had a similar problem and replaced IC2 and that seemed to cure it.  But by all means do the cap kit first--it needs to be done anyways and it might solve your problem.

Yes, a k7000 kit is the one to use on a 7191. This model does not use vertical output transistors. It has a tiny integrated circuit (IC3) bolted to a metal heat sink for the vertical output stage. Sometimes both IC2 and IC3 go bad.

I figure if I'm going to take the trouble of taking the entire monitor out I might as well replace anthing that might need replacing soon.

I guess I'm just going to get the cap kit, IC2 and IC3.  I dont know if IC3 is worth getting at 11 bucks its kind of expensive should I get it just in case?
