that plugs in or even on batteries can cause subtle problems like this. Basically they are all little interference transmitters due to cheap design, quality, & failures. It can get into the set via the line, antenna or directly into the chassis. 3 case histories ........... 1) When I sent CW it would turn one of my Zeniths on & off. A better ground for the transceiver fixed that. 2) Brand new Zenith had lines on all low channels not on old set. (It actually did but wasnt sharp enuf to see them much) It was the only set on ears. Cure was a calculator was upstairs recharging. 3) Just had a planned black out. What to do ? Listen to AM radio ! Almost every channel had a listenable signal as far as 300 miles daytime. When the power came back it went back to just a few powerful locals & lots of garbage. enuf fer now 73 Zeno  LFOD !

Out of genuine interest, I picked up another Trinitron (for free), a 1992 KV-20TS27.
It has exactly the same flickering issue! It must be something in the power, and the Tripp Lite isn’t catching it. Any suggestions for a better unit? What’s also interesting is that the ‘92 Trinitron is much fuzzier, even the OSD. I wonder if the set was always like this or it’s age-related.

A cheap set may actually work better BUT I got a feelin you will see
it on anything since you know about it. You could try tracking down the source. Turn off all house breakers except the one the TV is on. If it goes away turn them on one at a time til it comes back. Then you know the line & can unplug things. If you cant get rid if it turn the breakers back off & walk around with an AM radio listening for hot spots. Remember it can be something on batteries causing it. OH watch for loose cables on other things in the house. good luck Zeno LFOD !
