To the fellow who has a linearity problem (the characters at the top of of the screen get tall, etc.): Go to Radio Shack and get yourself a can of "freeze mist". Also, arm yourself with a handheld hair dryer. With the monitor running, and the back off, use the hair dryer to heat the innards some. This should cause the problem to appear more quickly than it would otherwise. Then, take the freeze mist and carefully zap components in the vertical circuitry. Observe the picture while you do this. When the picture snaps back to "normal", you have your faulty component. To the fellow with the jitter and bends: The jitter might be fixed by adjusting the "vertical hold" pot. I don't recall its location; it's been a while since I've had my monitor apart. For the bends, it's probably caused by a little too much enthusiasim when the previous owner stretched the picture. You might try backing off on some of those adjustments. The rings you see on the back of the yoke are for centering the picture on the face of the tube. -- Farrell T.
