running cost of 42 inch television set

[nice sax]

I am considering buying a new 42 inch Television set and would like to know the comparative running costs between a PLASMA and LCD set.

Not straightforward to compare like-for-like.
Panasonic are one of the few reputable makes to produce both types - and it is best to compare equivalent brands - but Panasonics don't make a 42 inch LCD (as far as I know).
Also there is a difference between 'rated' consumption (i.e. the maximum) and typical. The figures below are typical (not rated) from Panasonics own data.
37 inch Plasma - 189W
37 inch LCD - 134W.
So it looks like about 50% additional for the plasma over the LCD. Add say another 5% to both for the bigger screen size.
The data came from here:

This from Which?...

"...a 42-inch plasma TV typically uses 277 watts when switched on, compared to an 180 watt average for the 40-46-inch LCD TV category. That's 50% less energy than plasma televisions.

However, some TV manufacturers point out that the power use of a plasma television is directly dependent on picture brightness, while an LCD TV picture requires a constant source of illumination. The theory goes that a plasma TV should use less power over time.

But, in reality, plasma TVs require significantly more power to achieve the same brightness level as an LCD TV, putting something of a 42-inch widescreen hole in the theory."
