The only problem I have now is that my "Tiny Limited-15" monitor" has
developed "an inside pincushion distortion" which I tried to read about
in your book and the book explains how to remove them by using controls.
However, the controls have totally failed to adjust this distorton! I've
not found any information on adjusting the pincushion distortion right
inside the monitor. Some time it get away suddenly, then the controls
could work, but right now the distortion is persistent! I noted that my
UPS might have caused this. My UPS was very close to the monitor and I
noted that the far left bottom vertical margin of the monitor screen was
shaking when I installed another monitor (Toshiba). I removed the UPS and
I put it under the table and the shaking stopped! I suspect the closeness
of the UPS to the TINY monitor might have caught this pincushion distorton
which cannot be adjusted by the controls! Am reading hard to find more
about how it can be fixed. I wonder whether
you recent book talks about an altermative way of fixing this problem
without getting involved in buying third party machines to fix it?

Thank you profusely for the effort, links, all the vital information and
especially your books and videos! There are pushing me ahead!

Those symptoms indicate that your CRT may have been magnetized, or it may
simply be failing. You could try turning it on and off repeatedly, which
energizes the internal degaussing coil to demagnetize the internal shadow
mask, however it may be too far gone to help. In that case I'd recommend you
replace the unit, you can get used CRT displays for $25 or less, or purchase
a new LCD unit instead. Scott.
