I have pulled and tested multiple capacitors. They all test fine. Good ESR, values within spec.
I have reflowed many questionable solder joints.
I have taken apart the tuner and reflowed any questionable solder joint I could find.
Zero change.
There is a horizontal ripple in the image when something like bright lettering is on the screen. Also, the audio sounds a little bit distorted.
I am not sure where to go from here, but I am wondering if i should start tweaking coils. Maybe 40 years of use caused the tuner IF to drift a bit?
Additionally, working on this TV is hard when you have a cat:
Human! Human I need you to stop everything you're doing and give me attention!!
Some help on what to try next would be appreciated. I can post video of how the set is acting if it will help.
