I am an ancient, 1950's thru 1990 TV tech. Just starting to get interested again. I picked up a Motorola 7" VT-71MB-A television that when I fired it up on my variac and isolation xformer, it shows a bright pix tube with snow, but no audio. Where can I find a "Good" schematic for it?
Thanks

Welcome to VK. The Early Television Foundation has schematics (http://www.earlytelevision.org/tv_schematic_diagrams.html) for some of the chassis variations. Just scroll down to the Motorola section.

Good luck.
