We are new to LCD TVs, and we are thinking of installing a 32" screen above an open fireplace (hole-in-the-wall type). Does anybody have any advice on this? What is the maximum ambient temperature that a screen should work in and will high (but within spec) temperatures affect reliability / product life? Also we want to chase the cables into the wall to make a neat job, and it will be a lot easier if we choose a set with a separate tuner box. These do not seem very common, we have come across the Sharp LC-32GD1E, what else is available. Many thanks for any help.
