The most likely reason is that the components on the video board that  
control the yellow gun have changed values. This is a common  
occurrence as CRTs age, and is a result of heat and simple use. A  
trained CRT technician *may* be able to correct the problem with a  
simple adjustment, but it's more likely that the video board on the  
neck of the CRT will have to be changed. However, the cost of the  
repair may be more than the monitor is worth.

It I did a lot of graphics work, I would buy the best new monitor I  
could afford, and recycle the ViewSonic, whose age you didn't mention.
