Welcome Ron. It sounds like your convergence ic (board) has gone bad. Usually not a diy project unless you are used to that sort of thing. Have fun. Dennis
Dennis, we have dozens, probably hundreds, of folks who have repeired their own sets with this very common problem. If it is the common STK outputs and resistors, a person with a little soldering ability adn a manual for doing the convergence alignment can easily DIY these. Other problems that involve more troubleshooting and equipment are not good DIY projects, but these are usuall symptom-repair fixes that many can do.Welcome Ron.
