I wanted to do this in colour via hacking a video game box with audio inputs, but it never happened. There may have been a gimballed mirror effects projector at one time that did this on a large scale, dunno about colour/tone tracking.Dont have any Donna Summer ,, or FZ handy..... But here's some Floyd!!!
HA,,, I'm gonna feed it some square waves, and see what it can do...No more fun time, its gotta earn its keep!!!!
Now,,, I got a 32" CRT tv I moved to another room, and it stopped seeing any inputs,,, that may be a candidate for for video displays, if I can sort it out...
If you google the model , there is a way to get it into service mode, to do a factory reset (sometimes accessible in the regular menus) That would be my first thing to try.Well... I'd much rather getting the TV working again,,, Carried it to a B/R when I had help, hooked it up and no inputs seem to work,,, not sure if its a software problem,, or maybe the board flexed/cracked carrying it,,, still gets a full, clear screen from onboard source(menu, settings etc),,, but no external jacks work.... can't find a manual for it...
