I want to buy a new TV to replace my Sony CRT. My budget, including 5 year guarantee is £1000. To be used for watching sport, wildlife documentaries, iplayer, streaming from PC. will not be used for gaming or 3D. I will need to be placed above a radiator. I have spoken to a couple of Sony dealers who confirm it will be ok to place a Sony LCD above a radiator. Is it ok to place a plasma above a radiator ?
