INTRO:
This baffled me for a week. ha. The answer is at the bottom of the post, so if you want to think about it for a while, for fun, overt your eyes. I reversed the words so you can't accidentally see the answer.
STORY:
I was working on various B&W game boards, I don't have a B&W monitor so I just use the TV set composite in RCA (yellow plug) to get a picture, and I noticed I was getting a tingle of the board as I bushed it here and there. This happened a lot as I connected up boards. I had my fingers on top of the Switcher and my screw driver on GND and I got a tickle. :blink:
This was concerning so I checked the supply. There was indeed 60-70 volts between GND and earth. The voltage was there even when I un-pluged the supply. So I figured the supply was storing a charge. :o
So what could be???? Where was this Phantom charge coming from???
