A flat screen TV lasts around 5 to 10 years before it goes bad.
The more you use the flat screen TV the faster the TV will give out.
You should expect around 5 to 10 years out of a good flat screen LED TV although some cheaper models may only last 1 to 3 years.
A TV needs to be placed or mounted at least 2 to 6 inches from the wall for ventilation.
Whether you decide to set the TV on a console or mount it on the wall, the best height for a TV is actually the same eye level for a person sitting on the sofa.
In general, that means the center of the TV should be about 42” above the floor, regardless of the size of the TV.
Leaving the TV on all night does not use a lot of electricity.
On average it cost around 20 cents to 30 cents per night to leave a TV on all night.
I leave my TV on all night and my bill only increases by $1.00 to $2.00 per month.

The amount of watts that a TV uses depends on the size of the TV.
Smaller 24 inch TV's may use around 35 to 40 Watts while a larger TV such as a 42 " to 52 " TV could use as much as 100 watts to 150 watts.
Old CRT TVs were pretty power hungry and even for the smallest CRT TV it could use as much as 100 watts while a larger CRT TV could use as much as 200 to 250 watts of electricity when powered on.
Modern TVs use, on average, 58.6 watts when in On mode and 1.3 watts in standby mode.
The power consumption of modern TVs ranges from 10W to 117W (0.5W to 3W on standby).
On average, TVs consume 106.9 kWh of electricity per year, costing $16.04 annually to run in the US.
- 32” LED: 30 – 55 watts, but generally around 40 watts, - 32” OLED: around 55 - 60 watts, - 32” LCD: 50 – 85 watts, but on average around 65-70 watts.
For example, old 32” CRT TVs required up to 150-200 watts (even more if the screen brightness is increased) with an average consumption of around 120 watts.

Generally speaking larger the screen size higher is the rated power.
