If the monitor was good before and over time the problem started to show, 
this is an indication of some components failing in the sweep circuitry of 
the monitor. This type of failure is not an adjustment. Common failures are 
electrolytic capacitors in the related areas.  The power supply, and scan 
amplifier circuits are usually where most of the failures occur.  Capacitors 
usually fail from heat and usage.

If the distortion is horizontal where the image is distorted on the right or 
left side of the screen, the defect is in the horizontal scan or sweep area. 
If the distortion is in the top or bottom direction, the defect is in the 
vertical scan or sweep area.

With proper trouble-shooting the defective caps can be located and changed 
for new ones. This will take someone who is experienced in monitor 
servicing, and have the proper tools and instruments to perform the work. 
The main obstacle that the service tech may run in to is if he needs the 
service manual and schematics, and any dedicated parts.  The manufactures of 
most computer monitors will not supply service support to any non-contracted 
service tech facilities.

In the end, you may not find the cost of servicing a computer monitor 
feasible in relation to replacing it. At today's prices you can have an LCD 
screen for a very reasonable cost. Computer monitors are designed for a life 
span of about three to four years with normal use. After about 30,000 hours, 
they tend to start decreasing in their performance.

I've just noticed that circular objects become squashed inwards from
the right, the closer they are to the right hand edge of my screen.
Doesn't happen with top, left or bottom edges to any significant
extent - just the right. Circle looks like a lemon. No magnetic fields
in the vicinity. Degaussed anyway but made no difference.

This is an HP p930 19" CRT monitor. Although a bit apprehensive about
fiddling with its menu geometry options, I did play blindly with some
of them, but so far in vain.

Can anyone help me isolate and fix the problem please?
