These guys aren't joking about high voltages. I started playing with TV repair as a 12-year old, when I "inherited" an old TV from my brother when he went off to college. I was very confident that I could figure it out, since I had repaired radios and tape recorders successfully. I didn't know half as much as I thought I did
(typical for that age!
). I didn't know about how long those things could store a charge, or how big a charge. Unexpectedly discharging that voltage from a set that had been off FOR OVER A WEEK was one of the scariest moments of my life! Probably didn't help that it was iin very dry desert conditions. I'm lucky to still be alive after that. Do take all precautions!
