I don't suppose that this made it across to that other thread that has more than 2000 posts and climbing.

Ok!

Laugh all you want Andreas, I'm assuming it's a sarcastic laugh.
It's fact though that once a component is soldered onto a board, there's enough conductivity via the components on a board that there's no way a static charge can zap a chip. Loose chips, or during assembly of a PC board, or some RF circuit boards, that's a different case, and a ground strap and anti static mats should be used. I don't work on RF stuff though.
A PC board can sit at 20Kv, as long as every pin of a CMOS chip is at 20Kv, it's fine.

I know this not to be true, but if you want to work like that it is up to you. I would use an anti static mat and ground strap when working on projectors, better to be on the safe side.

The problem is that CRT´s are thrown in the waste in huge numbers these days and numbers are decreasing every day that passes and soon it will only be a very few of them left to repair.
Why do you have more than one profile in here??
