I've just started researching this, some people have older TVs from the 60s-70s and want to use a converter box but then wonder why their remote won't control their TV (the converter which has the universal remote or if not, the person goes out to buy one to control both the box and set so there's one remote instead of two) and i found it out, since one of my sets from 1979 has this issue.

A lot of the very early digital-tuning TVs, from the 60s-70s, Zenith Space Command, Magnavox Touch Tune, some Consoles, and RCAs having the 'Nipper' logo below the RCA letters, have what is known as 'Ultrasound emitter remotes' and those use a high frequency sound to control the TV wirelessly and was before Infrared came out. obviously a converter featuring a universal function or a universal remote are all infrared so they won't work with these older TVs.

So, i proposed something that may be of interest since i'm going to try it sometime. upgrading the TV's emitter sensor with a newer IR sensor eye so the TV will work with universal remotes or have the power function with converters with universal remotes. i'll let you know if there was success or failure since all i could have go wrong is losing remote capability but i don't have the blasted remote for it anyways so i really have nothing to lose trying.
