CRT monitors are assembled on hinged elements. Why not on SMD?

Question

Monitors

The question arose in the process of recycling old CRT monitors. It turned out that even the most (relatively) modern of them - say, with flat screens - continued to be made in the old fashioned way, using hinged elements. But at the same time, other computer components (for example, PC expansion cards) have long been riveted by robots on SMD components.
What is the reason for this "delay in development"? What are the specifics of monitors? What reasons could the board designers have been guided by?

Answer 1

There are several reasons.
Firstly, there are a lot of power elements operating under high voltage, and you can’t always make them in SMD. If you look, for example, into computer power supplies, and now there will be a lot of thru-hole elements.
Secondly, there is a lot of space, and there is simply not much point in shrinking.
Thirdly, the platforms themselves were quite old in development, plus there was a drop in demand, and there was simply no point in redoing something. RnD and production changeover is a lot of money...
