One man's trash... (TV Repair)

Alright, first of all I strongly advise you against actually opening TVs of any sort. If you still want to go ahead...

1. CRTs are "filled" with vacuum. That means if you accidentally hit one with a wrench or something, it might crack, break, and essentially implode in a shower of glass pieces. Not good if your hands or eyes are near. Plus it'd be a bitch to repair. Seriously, these things can be really dangerous.

2. TVs use extremely high voltage for their electron guns. Those are typically provided by capacitors and flyback transformers. Capacitors can remain charged for very long after you've unplugged a TV, meaning you can still get electrocuted and die. I'm serious here. There are sometime switches intended to discharge them during maintenance, but sometime those things don't even work. Lesson is, if you don't know what something is, or what something is connected to, then don't fucking touch it.

Those are probably the two main dangers I can think of, beyond the usual "unplug whatever the fuck you're trying to repair before opening it". But if you can't figure that part out, then you're probably an idiot.

Actually, if you still open your TV after what I've told you and have no experience with electronics beyond building computers, then there's a fair chance you're an idiot.

Jam it back in, in the dark.

I wasn't being hostile. A lot of people will simply decide it's not worth it after being informed of what can happen to them should they open up their TV and start messing around. Of those that do decide to go ahead, some will look at whether or not they have at least the common sense required and won't take any risk, which is fine. But a fair portion of the people that will go ahead won't, and those people are, for all intents and pruposes, idiots.

There's nowhere I can't reach.
