Sony Triniton KV-1330UB TV
On the subject of odd colour effects, it does take me back to 1983-4 and the arrival of a Sinclair ZX Spectrum at our house. Initially I put up with some strange colours (quite yellow white, brown red, nearly-black blue but the rest fine) on the Granadacolour set, but the colours were much better on grandad's Luxor and Panasonic sets. My cousins also had one that produced good colours on their set but it was never tried on ours... therefore I blamed the Granadacolour set for about a month. The replacement (due to what eventually turned out to be my dad misunderstanding the instructions for a task he intended to do) displayed perfect colours on every colour set, and even a noticeably better picture on monochrome sets. The original Spectrum was also a rather hot runner, the second much less so. That, too, was replaced towards the end of 1984 after something catastrophic happened, probably to its power rails. The next one had poor colour - notably washed out blue - and was replaced the very next day with another perfect one. The only problem with that was the occasional need to retune the set slightly (we had an ITT 16" set about a year later and it was mainly that one this applied to).
Some sets can be temperamental, colour wise at least, with some sources. It is worth having more than one source available to test with.
My old Sony is quite happy with an RF input from a HDMI modulator and Chromecast, looks poor in photo but much better by eye.
However my TV is a CVM1330UB, which has an isolation transformer and video inputs on PL259 connectors and an EIJ connector.

Just confirmed there was a tint control on Tandberg CTV1s not that I ever saw one of these. CTV2-2 had a few controls behind a bottom hinged flap and I think one of them may have been tint, but I'm not at all certain as I haven't seen one in nearly 40 years.
