Question about Projection Televisions
I have a Panasonic rear projection tv Model TX-51P400H which is now 5 years old. Upon turning on the tv recently the picture was out of convergence with three images on screen - one red, one blue and one green. The only previous indication of a problem was for the previous month the tv when turned on showed an overly bright picture without much contrast. It settled down after an hour or so. All attempts to adjust the convergence with the remote control following the operation manual for the tv failed to achieve a satisfactory result. The best result obtained to date is a reasonable image in the centre of the screen with the perimeter of the screen still showing the three images (red, blue and green). After a short period of time the convergence goes off again. A technician friend (retired) replaced the brightness capacitator as his past experience with crt tv's indicated that this can effect convergence. This made no difference to the convergence.
