I don't think the back of our tube-based TV was ever on.
While it was under warranty, service people seemed to arrive monthly.
It was a routine task for me to be charged with pulling ALL the
tubes and walking up to the corner drugstore (where they had a
tube tester) to check them. Invariably, one would be "weak",
replaced and then the TV returned to "new" condition. A fair
bit cheaper than a replacement TV.
When it was out of warranty I learned a lot about the practical side of electronics.
Eventually it ran reasonably reliably until the picture tube gave up so my father and myself replaced the A66-140X

I don't think the UK ever had any tube only colour TVs, they were all hybrids (tubes for high power / high voltage) and
semiconductors.
In the above case all discrete except for one integrated circuit (line oscillator).
