It was 20 years ago, and now I live in a house without central heating and cable TV , so I can not reproduct that effect.
But I remember for sure that the distortion similar to that which you get from spark plugs of internal combustion engines, about half a TV scan line long and repeating itself about every 3 to 5 scan lines. --------------------------------------------------------------------------- ------------------------------------- ----------------- To: Rene Charton/TUV-Twn cc: 102630.1...@compuserve.com, emc-p...@majordomo.ieee.org Subject: Re: explanation of ESD events with coins in baggie. Rene, That is an interesting phenomenon! If you could give me a more detailed description of the TV "distortion" and "black lines" I might be able to explain at least what was happening inside the TV set (I worked many years in TV R & D). This in turn might help others to explain what ESD or EMI effect it was! For example: Are you referring to picture geometric distortion, color distortion (or was it B/W?), interference "flashes", loss of vertical or horizontal synchronization etc! Also were the "black lines" random, diagonal or what spacing etc? Also "many years ago" TV's in different countries might react differently, so where were you and about what year did you see this?
