Why does a plasma tv get hot?

Answer 1

This is caused by "wasted" power in the electronics of the TV that is not actually performing the functions of being a TV, in other words the fact that the TV is less than perfectly efficient. This is not only true of your TV, it is true of everything: everything is less than perfectly efficient, everything "wastes" some power, everything heats up when used.

Note: even an electric heater "wastes" some power as although its function is to heat up, some of the power it uses comes out as visible light instead (and even a very tiny bit comes out as microwaves) which in not fulfilling the function of being a heater.

Answer 2

The LCDs that compose the front panel of the TV don't emit light but affect the amount and colour of transmitted light, so there has to be a light source to shine through them. With most LCD TVs this is a bank of fluorescent tubes behind the screen. Though fluorescent tubes don't generate as much heat as, for example, filament light bulbs, there is always some heat produced, and this is what makes the TV hot.

Answer 3

All electronics get hot eventually as they run. It's important to keep the vents clear of any obstacles and to keep them as free of dust as possible. I blow the dust off and out of the vents of my electronics often, at least once a month, with canned air.

They get hot because electricity encounters resistance as it flows through the device. Wires have some degree of insulation that reduces the heat, but it still builds up anyway. Parts such as processors (which today's TVs have now) and motors get especially hot.

because its been on to much
