Being in the repair business doesn't mean I know all. I have a set here that has a color issue. loss of green primarily is the trouble. I say this because the picture is either all red or red and blue or all blue (during this time total loss of color accured.) I found many solder joints that needed attention. used freeze and heat. swapped video output transistors. some of these i believed cured the problem.i am now thinking is the jungle chip, caps around it. help is needed. thanks in advance.
