Its a long time ago, but VT7 rings a bell

As for the uncontrollable brilliance etc, there's a set up procedure involving the set white switch and at least two presets, I think one is in the Frame Board, cant remember now once done they can produce a half decent picture, not sure if a Thorn New Life CRT is much of a positive They had a poor reputation back in the day.
As for the loss of Video, check the Decoder PCB, if it is fitted with the Thick Film Video out put module, they were notorious for intermittent faults, such as blank white raster, smearing etc etc.
