Hi,
A 140 watt TV will draw about 14 amps from the battery bank.
14 amps is a little high. Current can be derived as follows: Wattage/Voltage = Current. So 140 Watts/12 Volts = 11 2/3 Amps.
Not only that but my newer Magnavox 32" LED/LCD screen operates at 32 watts. Allowing for a 10% loss through inversion, draw would be in the range of 3 amps at 12VDC. If just using a single battery, the OP would be able to get a few hours of use daily and a small solar system would make up the difference easily.
