Discharging CRTs is a relatively simple process, the concept is no different than what occurs when you see a spark from static electricity which has been stored in your body when you touch grounded metal. The key difference is the charge. The CRT stores thousands of volts when turned on and uses this high voltage store to supply the required energy for picture display and continually replenishes it, but when the tv is off normally there is a slow discharge and although a charge can be present in CRTs even if they haven't been used for some time, this usually is not a significant amount compared to the extremely high voltage when turned on. However, it can s be enough to take precautions to avoid. The potential lethality is overexaggerated and it should be reassuring to remember that though the voltage is extremely high, it is current that is dangerous. High voltage contact tends to to travel across the skin to ground without touching organs, and if discharged properly there is little chance of shock. I highly...
