Do all LCDs have backlight bleed, in the corners and such?

I just exchanged a 40 inch LCD or an same-sized LED-LCD TV the other day, hoping I would no longer have the annoying backlight bleed in the corners. The new TV just has the bottom corners lit up instead of the top corners. Not as bright either, but still a little annoying. Keep in my mind that I'm budget-constrained and spending a thousand bucks or more on a higher quality TV, maybe not purchased at Walmart, is not in the question right now!

I'm beginning to think that if I want an LCD or LED TV, I'm going to have to deal with backlight bleed of some sort! I've heard they all have it to some extent.

There is a 43" plasma in my price range, but it only goes up to 720p (as opposed to 1080p). I've also heard that plasma have bad glares due to glass screens. At this point, I don't think the 720p thing would bother me, because I can't tell a damn bit of difference between a DVD and a Blu-ray in terms of quality anyway! Of course I've never watched the same movie on DVD and then Blu-ray, so I can't say for sure, but the only significant difference I notice is the cost! Is this another problem with lower budget TVs?

I'm really starting to miss CRT (old school) TVs. Bigger picture size and HD doesn't mean squat to me if I'm forever having to deal with backlight bleed or terrible plasma glare. Any advice or help would be appreciated. Also, if anyone knows of any really good TV models at Walmart (or the like) for like $500 or less, and can let me know what they are, that'd be great! Thanks!
