If the flyback "tire" or tertiary winding is overheating,that can be caused
by the plate cap not having a good,sound connection on the hv
rectifier tube.I had this happen on my Conrac color monitor and just
recently with a rca KCS-153b chassis.After the set was on for about a half hour,the picture began to shrink and get real dim.I could smell the flyback
burning.I was really bummed out about having a bad flyback when I decided
to pull off the rectifier plate cap and clean the cap contacts and the
2bj2 plate cap itself.Well,I was rewarded with sucess.The flyback no longer
overheats and I can run the set all day without any problems.By the way,
having a good connection there is extremely importaint for color sets,
especially ones that use shunt regulators.A bad contact with the hv rect.
tube in those sets could cause the set to burst into flames.Flyback fires
were a common cause of tv fires back in the old days.
