I always remember back in the day, pre plasma and LCD, people always said “don’t ever open up and mess about with your TV, even if it’s been unplugged for a couple of days, there’s still some electrical components with enough charge to kill you”.
I assume there was some truth in this?
And does it still apply to modern TVs? Amir’s post got me thinking about this, I had forgotten all about it.
With CRT-type sets, it was customary to discharge via the flyback transformer anode clip, and I was always super-careful to do this. But even 50V stored in an electrolytic capacitor can scare the #@$% out of you if you suddenly discharge it! Even with modern circuits, it's always a good idea to probe some of the larger capacitors to ensure they're not still charged.
