This thread actually reminded me I still have a Braun TV3
(all pictures for illustration purposes from google, not mine)
That thing is like 26" if I recall correctly, and if I had to guess, about 40 kg. Can't even imagine double the size. It's gimmick was is that you could press the button you see to the right at the front and angle the tube up and down while holding the button. It was a fully mechanical mechanism. The idea behind that was to get rid of reflections from light sources IIRC. It came with a HiFi system it was supposed to be on top of, I still have that one too + the VCR of that system.
It all had tons of little green lights and big green segment displays so you knew it's the future. the controls you would press and they slowly would slide out to the position you can see on the second thing which I think is the amplifier?! (I didn't see mine in decades and genuinely don't remember, it's somewhere in the attic) Very la-di-da. The remote control was the queerest thing I ever saw:
It already looked odd like that; the special gimmick it had was that it would control everything, not just the tv:
it had a little sliding mechanism at the top where you would set what you wanted to control:
and that would flip a specific card with the descriptions of the buttons over the buttons which you could then see when you pressed the open button (you could only set the system when it was closed, of course) it would also set a little slider to the right you can see in this picture, so the remote knew which system to address:
All fully mechanical, no electronics involved. (besides the remote itself of course) Very fancy, about forty years ago. Godamn, I'm old. I think it was wildly unsuccessful. Used it way into the 90s. I think there was something wrong with the antenna modulator. All Made in W. Germany.
