ctc197 certain blue colors flicker

[timmy]

hi all, i have a ctc197 rca that i have repaired a few times over the years and recently when turning it on it has a nice picture and works fine but the first about 1 minute certain scenes with blue are flickering like a scan problem but im not sure. im just trying to maybe get a heads up on what this may be in the near future. its only blue colors and on the right side lower screen. anyone ever have something like this on another solid state set. the set is 15 years old but still works like the day it was bought but i have replaced 2 flybacks and 2- 2kv disc caps over 15 years thats it but something different here is happening. so when it goes bad or maybe befor it gets worse i would like to try to get something on it to go to. i dont have a schematic for it so ill be in the dark on this one,lol,lol.
