Thanks for all the input. I guess, for the person who only looks into
the back of an operating TV once or twice a year, the hazard is
minimal. However, if my job were to be looking into the back end of
operating color TVs all day long, day after day, year after year, that
might be a different story. I wonder if there are any full-time TV
servicemen (women) who follow this NG who could give their input?

Cheers
