Something to think about. TVs draw about half of their full rated power draw when OFF. The LCD TV that came with our 2010 8626RLWS has an OFF switch behind the unit that kills power completely in addition to the on/off switch in the front that turns the TV on/off but keeps the "instant on" circuitry burning.
Most "home" type TVs would need an additional power kill switch to give you similar parasite draw protection. Plasma TVs draw the most power in use while LCDs draw less but have viewing angle restrictions.
Our LCD TV can not be seen at all when lying on the floor or sitting in a bean bag chair.
If you go with a larger TV watch the weight. Although the wall mount has VESA mount hole spacing I doubt the cabinet could handle a heavier unit without more bracing.
