Well High Voltage is the reason you never open the power supply... of anything. LCD panels also have a HV power supply. Photo/digital photo Cameras have a high voltage in the flash unit. Pretty much you can be killed by these things, but you have to be nucking futs to poke stuff you don't know with a screw driver.
The x-rays though are harmful and removing the shielding from the CRT exposes you to excessive amounts, and if you don't put it back properly, you are constantly irradiationg yourself. That's why there is 20 pounds of lead in them or something.
The voltage, stay away from the big red wire, that's the one that will kill you. In newer CRT's (ones with microprocessors instead of dials) the microprocessor board is easily identified and played with... just they are pretty much solidstate, unless you are replacing the board, there is nothing you can fix. Which goes back to the supernova effect, the electricity driving the magnets is not from the microprocessor board, it's from the power supply, the microprocessor only tells some relay somewhere else to make adjustments, and if once of those relays goes BANG, or something, then you lose the ability use that frequency range. I think I'm remembering this right.
LCD's on the other hand are like 2 or 3 PCB's, panel and backlight, of which only the backlight/powersupply can kill you if you poke around.
