You've adjusted the vertical size out all you can? Not sure what monitor that would be as I am not familiar with the brand.

Yes ive ajusted it out all the way:( When i bought this monitor it had no chassis at all, so i installed it with my existing board. plz help me!!!
 
Take some pictures of the monitor chassis. It could be possible that you just have a bad vertical pot that reared its ugly head when you did the swap.

And you have a Wells Gardner K4900 model monitor chassis. (not Zetro...)

I agree that you need to swap the yoke, use the yoke that came with the K4900 chassis.
There are threads and tutorials floating around, just have to search a bit.

ive looked all day, i cant find them!!
 
Do you have the old tube? You need to remove the yoke from the old tube, and put it on your new tube.

and that's only easy to do if you say it quickly!

unless you are pretty polished at it you will all sorts of convergence and purity issues - I would be seeking some help from a technician at this point
 
Thanks for your help guys. Does anybody know where a good tutorial is on the net? I've been looking, but can't find one with pictures.
