Replace it. CRT? No offense, but its just probably too old... I mean look at it, its...OLD.
prob a poor guy dont make him feel worse but i was thinking that reapir cost as much a used slim monitor
I definitely did not intend to make anyone feel bad, but what you said is really what I meant. Check craigslist for a used LCD, or eBay, or Pricewatch.com. Lots of options, and an LCD probably uses less power (and is easier on the eyes) than a CRT.
