Well, after taking a morning kindergarten class of cutting and pasting - here is the complete Admiral combo unit I have on a one page schematic. It is a PDF file and you can zoom in on it without loosing too much resolution. Assuming it uploads ok here.
My specific combo is the 21L1 TV chassis combined with the AM/FM radio (5D2 model). I had to cut the radio portion of the schematic and paste it onto this page with the correct TV chassis schematic. But you can see the dotted line separating the two sections and they meet at the PLUG which connects the radio/phono unit into the back of the TV chassis. Looks like I need to concentrate on SW501 (just below the plug diagram on the right side of the schematic). This is the TV on/off switch.
Now based on my above video of symptoms and this schematic, anyone have any plan of attack for me that would yield a solution? I obviously need to trace the wiring in the set from the AC-in line through this switch and make sure everything is hooked up correctly. That is my first step. However, if someone can explain based on this schematic how the set SHOULD operate, that would be a huge help.
Thx. Let me know if the PDF file is not adequately viewable.
