I'm sick of light-bleed in the corners of LCD TVs? Is there nothing I can do?

First of all, I'm stuck in buying TVs from the "budget range" of LCD/LED TVs at places like Walmart. I recently returned an Emerson 40" after getting so sick of the light-bleeding or "flash lighting" effect coming from the top corners of the TV. If the two light bleeds had been the same size, I maybe could've dealt with it, but one was much larger and brighter than the other. I returned it yesterday to get a HiSense 40" LED model, only to have the same problem, but in the lower corners of the screen! The light bleeds aren't nearly as bright, but it's still aggravating, and I don't feel I should have to deal with this, even from a cheaper TV.

Is this just a common problem with LCD and edge-lit LED TVs that I'm just going to have to deal with unless I can spend $800+ on a different model? Does Walmart (or similar stores) have any TVs that don't suck like this?

I found a 43" plasma by Samsung at Walmart in my price range, but it only went up to 720p, although some people seem to think that since it's plasma, the picture will be better, and I won't have an issue with not having 1080p. As it is, on these other TVs, I can't tell much of a difference between some HD (like Blu-rays) and standard def anyway!

I appreciate any advice anyone can give me. Thanks!
