It's funny how people seem to collect old TVs who have little to no knowledge of their workings, or of broadcast terminology/systems. Sort of a classic-car collector who doesn't know how to calibrate a carburetor or do an oil change and filter change. To each his own though--but it costs considerably more to not know, in both hobbies mentioned.
As for the 'Concerto' from the O.P., I will assume it is nonworking 'til I see a screenshot he-he-he
