Why are there no tube televisions anymore?


It’s funny when you come to think of it and compare video with audio. How come in the audio world discussions sometimes become intense, while there seem to be far less intense discussions in the TV & video realm?

With TV’s there’s no talk on tubes, transistors, analog, digital, vinyl, cables, power cords, heck we can even get ’audio’ fuses and -USB cables.

No one has a tube TV (while they really have a ’warmer’ image :) and very few people use a $400 power cord with their TV set. And while there are expensive HDMI cables on the market, the vast majority uses one below $50. And no one spends money on floor spacers to avoid cable vibrations.

Our eyes may even be far more sensitive than our ears ... yet discussions are far less intense. How come?

Different hobby.  Recreating pleasing sound/music is different from video interests.  The are many different preferences for audio sonics and many methods to achieve them.  TVs are resolution based so there is much less reasons for debate the end products-likely just which video resolves better.  
I think someone compared tweaks to religion.  Some people just don't know about not discussing/comparing politics and religion here.

It's not about superiority oldhvymech. That's not how I read it.  
I still have a clear memory of helping my Dad pull 15-20 tubes out of our b&w console TV once or twice a year, when it was acting up, and driving to the Bernstein-Applebee electronics store where we’d kill an hour or so testing each one a couple times. We’d get several that rated "good" a few that rated neither good or bad and 2-3 that tested as "bad". We’d buy new replacements for the "bad ones, put them all back in the TV, cross our fingers and turn it on. Sometimes it worked and sometimes We’d have to go back and buy replacements for the ones that tested inconclusive.
It was a pain in the rear and waste of time.
I don’t miss tubes in TV’s at all.
I also remember that TV repairmen did housecalls then and kept quite busy.
My father and I built a Heathkit mono tube-amp for our 45 player and a guitar amp that I used in a terrible garage band in the 60’s. The Heathkits were rock solid.
Size, weight and cost.
The last large crt tv I worked on was all crt inside. The plastic case was molded around the tube.   I think it was a 32". The circuit board was only about 8" x 10".  And I could lift it myself.  A 32" all tube console took two people to lift.  20 or so tube cluttered inside around the crt. Just to heat the filaments on those 20 tubes took 25amp at 6 volts.  High voltage!  Zenith anode voltage was 35kv on their larger unit.  42.5 rings a bell.  CRT convergence was touchy to get a sharp image.  With age the crt would go gassy.  The red, blue and green color guns would go weak and need balancing.  My dad spent $850 in the 60's for our color tv.  I kept it going into the 80's.  Glory hallelujah they are no more.
