I have a Hanatrex MTC9110 from the early 90s and for the past month that I've owned it everything has been great.  Just the other day I noticed one pixel on the right center of the screen has "gone out" and remains black constantly.  I know this is something common on CRT monitors, but I don't know if there is a fix for it (at home).  I can't find anything about it in these boards but figured someone would know where to direct me at the least.  
Any help would be greatly appreciated!
