Approximately 1.625 Amps per hour if plugged into the wall. Wattage is equal to Volts x Amps. In my case, my 40" Samsung LCD uses 195 watts, and at 12 volts(for a deep cycle battery), that would be using about 16.25 amps per Hour. I was trying to figure out how long an 80 watt solar panel could power my tv. With a fully charged 55 AmpHour battery, it could probably stay on 3 hours. Don't forget though, you don't really want to drain a battery past 50% because going lower decreases the life of the battery. So figure about 1.5 hours for a 195 watt tv at 12 volts on a deep cycle. For outputs from the wall, I think it's 120 volts, so 195 divided by 120 is 1.625 amps per hour. You might think since there are less amps there is less power, but amps isn't power, watts is. Current is measured in amps. Since there is a higher voltage, there needs to be less current. Think of it like a river. When the water gets deep and the river wide, the current flows slowly but there is still the same amount of water passing through. When the river is shallow and fast, there is also the same amount of water passing through even though the current is faster. I know it's kind of confusing because all the components are tied together, but after a while, you will understand it.

depends on the size. a 42" LCD TV will use in the order of 150-250 watts, which is (divide by volts=120) around 1-2 amps, say 3 to be safe...

This information would be printed on the TV near the power cord. Every brand and screen size will be different.
