Am about to buy a new TV and have been leafing through the Dec What Hi Fi "Best TV's you can buy" supplement and have come down to two choices:-

Samsung LE46F86 or Panasonic TH50PZ70

The Panny is calling to me, based purely on size but I am concerned about the power consumption. Despite researching this subject on the net, I am still somewhat confused.

Is it true that a plasma is much more power hungry than an LCD and if so, what does this mean in real terms?

It's swings and roundbouts - LCDs have slightly lower continuous power consumption, but it is continuous. Plasmas, by contrast, have higher power consumption when showing very light scenes, but less when showing very dark ones - it varies according to how much of the screen is lit.

Thanks Andrew - that seems to sum up the situation nicely!

Andrew's right. The LCD lobbyists have done a fantastic job of smearing plasmas (ironic, as LCDs do more on-screen smearing...) re power consumption, often showing sets of figures that compare CRTs or smaller LCDs to larger plasmas.

Personally, in the power-use stakes, i'd rather watch less, better-quality TV than keep an inferior set on for longer....(Which is why I use a projector - it means you only switch it on when you really want to watch something!)

Many thanks for your reply Clare. Ended up buying the Panasonic 50 TH50PZ70. Have noted the later debate about the merits of the PX's vs the PZ's. Considered this myself but in the end thought "I've got the dosh so why not!" Also bought the Sony DAV-IS10 system based on the reviews in your excellent mag - the missus couldn't complain about such tiny speakers.
