DON'T even think about touching those! they adjust the convergence and color purity and are a major pain to get right again if fiddled with since several of them interact with each other and adjusting convergence is just plain tricky! there should be pots on the circuit board(s). there is a clamp on the deflection yoke (the wire windings) that should be snug (but not too tight or you can snap off the end of the tube), check that first. the rotation can be fixed by just barely loosening just that clamp (again, be careful not to disturb the other settings, particularly the rotating rings, they are a real pain!) and rotating it to get the display straight. there should be a pot on one of the boards for horizontal offset or phase, that will move it side to side. the "compression" is vertical linearity adjustment pot. the sides being pushed in is "pincushion" adjustment pot.
be very, very careful working on the monitor hot. it's very useful to set up a mirror in front of the monitor since you have to be behind the monitor to make the adjustments. it can be done with 2 people but is much more difficult that way, and really hard to do by yourself if you haven't done it many, many times (i have and still usually use a mirror). some medicine cabinets have mirrors that are easy to temporarily borrow. there are very, very high voltages in the monitor, and allot of it runs at a high enough voltage to be a problem. contact me off list if you need more help. > There is a large whitish plastic housing on top of the back of the > tube, with adjusters labelled: > XBV > XCV > APH > TLH > TLV > YCH > YBH -- The right of citizens to bear arms is just one guarantee against arbitrary government, one more safeguard against tyranny which now appears remote in America, but which historically has proved to be always possible." --Senator Hubert H.
