Poor picture quality. Picture also tends to curve


The curving is caused by bad digital convergencr chips (2) located on large signal board. They need replaced along with blown pico fuses and the convergence resistors. Chips are huge compared to a regular IC. 2" x 1.5" and they will be bolted on fairly large heatsinks. Cloudy picture is most likely the coolant needs replaced in the picture tubes. This needs to be done approximately every 5 years.

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

You need to have the convergence IC's replaced. A repair like this should run you about 300 bucks or so. In most places.
