Based on the discussion, it seems like "a good tv" to you is something that would be reliable and last a long time:
It's pretty hard to guage how long a current market tv will last as these specific models have only existed for so long. So it's hard to know if a specific tv will display as stunningly beautiful images 10-15 years after purchase. LCD TV technology usually has a lifespan of about 30,000-60,000 hrs though (Plasmas lifespan are shorter ~20,000). Based on what your specified typical usage (16hrs/day) though that comes out to about 5-10 years.
In terms of brands I would stick to the more common ones: Sony, Samsung, Panasonic, Sharp, Toshiba, Pioneer... and probably stay away from the lesser known Vizios, Dynex and also Dell, etc..
Most the more "known" manufacturers provide generally (not necessarily every model) reliable sets, of course there will always be the exception cases, but most of them have stayed in business this long because their products typically meet a higher level of quality. There aren't huge differences in reliability between those brand names.
In terms of picture quality, those brands can vary quite a bit more. Even with sets having the same screen, picture quality can still be largely affected by each brand's priopietary picture-processing. In that regard, I agree with Jai that it's pretty much Sony and Samsung that are at the forefront of picture quality for LCDs, but that just means they make the best sets disregarding price. It does not necessarily mean they make the best quality picture for a given size and given price range.
You really need to look at what you want in your tv and what is important to you. 1080p? (1080p for sets under 37" are not always standard) Refresh rate? (60hz/120hz) Contrast Ratios? (How black do you like your blacks? Michael Jackson black?) Power Saving features? (especially considering your daily usage) Screen/Color Uniformity? Number and types of inputs? Audio? Asthetics? And most of all Price! For some of those different picture quality aspects you may not even be able to see a difference. If you can't tell the difference I wouldn't bother with it. The picture should just look good to you, regardless of the what the specs say.
I recommend settling on a price range first, and trying to find the tv that best suits your needs/wants within the range staying with the more "known" manufacturers. And Duncan provided a great resource in avforums that supplies lots of info on almost all tv brands and models. Once you have a specific tv picked out, price shop it. Find out what Best buy charges, futureshop, south van color tv, etc...
Also if longevity is important with your purchase, good maintenance goes a long way. Especially with excessive usage, setting aside some extra budget for a surge protector, making sure the tv is well ventialated and lowering the default brightness (sometimes defaulted for a showroom and not necessarily the home) can go a long way.
