I suspect you may have a short in the horizontal deflection circuits or High Voltage transformer. If the set had a "great" picture, it may be worth fixing providing you aren't planning to upgrade to a HDTV anytime soon, otherwise I would use this excuse to start looking for a new set. Worst case I can envision with this set would be one of the picture tubes having a Short, keeping the set from turning on. That would make it unreparable.

The power board has failed and will need to be repaired or replaced. you can remove this board and, replace individual parts and save a lot of money. You will be inspecting for swollen capacitors and resistors. also, look for discolorations on the board itself.

Convergence is way off, Rt & Lf side of screen has red & blue around objects


Convergence IC's inside of your TV have to be replaced. Also some low value resistors around IC's could be burned as well.
Then convergence have to be realigned. This job require above-average soldering skills and cost around $300 if you hire TV repairman to do that.
