Convergence After 5 years of excellent peformance, the convergence problem began to show up, first as an intermitent loss of convergence over a period of about six months. Finally, yesterday the blue and green curved into a horizontal arc (pin cushion?)ie top and bottom half curved in towards the center of the screen. Blue convergence adjustment now has no effect. Red seems ok as it is still linear and still adjustable. Video and sound is OK. Need advice on possible areas of concern particularly on a most likely chip that governs the green and blue crt convergence controls. The symptoms of intermitent failure to total failure of the convergence adjustment seems to indicate a possible gradual degradation of a certain chip rather than an intermitent connection or a bad solder joint. Any advice from anyone with a similar experience?
