Hey gang, thanks ahead of time for any help and advice. I have always wanted one of these, found this one today for $100.00. It is an upright, appears to be original from 82. Rough shape, when plugged up I hear the speaker popping and humming but nothing else. Monitor doesn't power on nothing seems to come on. I have been an IT guy all of my life, even used to build and repair dialysis machines, so I should be able to handle it, just not sure what it should look like inside, couple of plugs don't appear to go anywhere, there is a reciept inside from 2013 showing monitor was replaced. It is a samsung. But everything else looks original except maybe the power supply. Again, not sure. First one I have ever opened up. The monitor control board for lack of proper term, that adjust vertical and horizontal position is just hanging in the cabinet un mounted, but does appear to be hooked up. But really no power other than speaker. Any advice or any pics of what it should look like inside?
