Even a pensioner can afford £1 a day.No it isn't.
Your only option is to buy a new TV.
Any money spent on a clapped out old plasma effort will be 100% wasted.
Even if a miracle occurred and you managed to fix it, the cost of the vast amount of electricity it uses compared to a modern one would buy you a new TV in less than a year.
Is a plasma TV expensive to run?
However, if you have a plasma TV, which averages around 350 watts, it consumes 0.35 kWh per hour. Therefore, if it's turned on for 8 hours a day, it will cost about 62.6p per day or about 7.8p per hour.
