The back of the input button in the middle. Can't tell if anything is wrong with it or not.

Not only do they have capacitors that can kill you, but the tube itself holds a pretty strong vacuum. If you rupture it, it can implode, killing you with glass fragments.
NEVER perform maintenance on a CRT unless you know exactly what you're doing.
