Older CRT televisions and some LCD televisions store energy in capacitors at high voltage. In some cases, the high voltage can remain for days or weeks after the television has been switched off.
CRT televisions carry up to 20,000 volts while LCD televisions often use a few hundred volts to drive the back lighting. Both can cause injury or death.
If you need to ask this question, you are not qualified to be repairing televisions nor to remove parts safely. Please never remove the covers from televisions unless you are trained and qualified to do so.

Can you repair a cable connector on a TV?
A television technician may be able to do this task - I certainly wouldn't attempt this project by yourself. It will require removal of the circuit board that this CATV connector is soldered to ... dangerous voltages haunt inside any TV, even if it is turned off and unplugged. The television tube, basically a huge capacitor, stores thousands of volts for a very long time, and if not properly discharged by a qualified technician, that kind of voltage could cause someone great harm, possibly death!! Forty Kilovolts is something to definitely be afraid of ... !

Can a television shock you?
Yes, is the short answer. Old TVs with a cathode ray tube, can build up a static charge on the front of the screen. You can sometimes get a harmless shock if you touch it when working. These old TVs also generate a very high voltage inside, to accelerate the cathode rays. The tube can act like a giant capacitor and store this charge even when switched off and unplugged. Keep your fingers out of the back, unless you take professional precautions. All other TVs, including LCDs and Plasma, have power supplies which store high voltage in their capacitors. This voltage is also maintained even when the TV is switched off and unplugged. Again, you are safe as long as you keep your fingers out of the workings. Qualified personnel are knowledgeable of the stored voltages and know how to deal with them safely.
