It's just the risk. Most components in a modern TV are very safe to work on. Even the PSU is not that bad. CCFL backlight had voltages only in the hundreds of volts, and modern LED backlight is even lower. A CRT is totally different business. The author of the article pointed out another thing, wire insulation properties at such high voltages.

There's just a lot to consider, and extremely high voltage stuff isn't really my area. I tend to do more low voltage stuff. When things go wrong with high voltage they tend to go wrong pretty spectacularly, and can cause serious bodily harm too. I just prefer not to take the risk. I'm similarly cautious with Li-ion and Li-Po battery charging circuitry. I don't like to mess around with those and if I repair them it's purely a like-for-like repair.

Another thing is that when I started with electronics CRTs were still very common and I wasn't skilled then, as such I had a lot of respect for them and a lot of caution. As my skills grew, CRTs became obsolete so I never really got comfortable with them and the apprehensive feeling remained.

But I think I have skills with electronics yes, I repair a lot of electronics, designed some of my own and I also built and modded some radios, and came up with some of my own mods (I have a ham license too).
