Probably the deflection transistors overheating.  You might want to freshen
up the heatsink grease, as well as drill some holes in the back & mount a
fan to blow across the deflection board.  While you're at it, you may want
to upgrade the transistors to a bigger package (w/ more surface area) - see
http://www.repairfaq.org/REPAIR/F_VAtari6.html .  Even if these things
don't fix the problem, they'll extend the life of your deflection board.

Good luck!

PS Don't work on a monitor unless you know how to discharge it properly!
