Hi, try gently tapping the monitor while adjusting brightness to
help determine if it might be a bad solder connection. If brightness
alternates or flickers you may just need the flyback or grid circuit
resoldered.
The other test is more technical, but if the cover was removed by
a tech he would be able to adjust the screen voltage next to the
focus adjustment located on the flyback. If turning this pot helps
your in luck and may be able to compensate for the weakened
flyback. If it doesn't work you'll probally have to replace the flyback
transformer.
Flyback failure is the second most common problem I've seen.
Second to horizontal output transistor failure. I have coworkers
that would argue the most likely reason for the failure is either
heat build up or power quality issue.
A few don'ts to help preserve your monitor:
1.) Never power the monitor simultaneously with other devices
2.) Never run the monitor from an extended power cord or
video cable unless those cables are larger or the same size
as the original
3.) Never exceed the max. rates of a monitor such as refresh
rates or vertical synch rates or resoulution
4.) Video cards can and do kill monitors. Do not match a large
monitor to a budget video card. Some cheap and older
video cards operate outside the range a large monitor may
require when exceeding 1024 x 768
5.) Never max out brightness or contrast settings
6.) Never change monitor settings if you suspect the
wrong video driver is being used
7.) Never power your monitor from the pc's aux. outlet
unless you have no choice
Please note the above are opininions and not fact.

yes it's normal
