I have a Mitsubishi 55 inch rear projection tv, ws55819 on which the convergance is gone bad. I'm getting a concave picture with multiple colors and black lines with a blurred picture. this happens mutiple...


Your reference to concave picture suggests a high voltage problem and not convergence. If the raster can't scan from left to right , top to bottom, your having High voltage trouble. if your colors are not dropping on top of each other that is convergence. I would suggest it may be time to consider a purchase of the new HD set for the cost of this repair. good luck

Picture on projection screen is concave in the middle


This set does not use IC's for convergence. Most other brands do use IC's.They use individual transistors in this one and honestly I don't remember ever seeing these go bad. Normally it is the power supply that runs the convergence transistors or more commonly known as the convergence board. It gets pretty technical with this type of problem. Have a repair shop check it out for you and avoid the headache. Thanks
