RCA cd197 36inch color

[timmy]

Ok I have this RCA cd197 color and its from 1996 works great but they are known for flybacks every few years but for awhile now while watching the screen flickers bright and the images have a blue smear on them then it will be normal but does this at random so the question is that is there anyone that has had something similar to this problem. Maybe a bad cap on the neck board I really don't know but the set works great and I want to try and track down a cause and fix it. Any ideas would be great.
