Query: Poor picture quality

Did a bunch of research and decided to buy this tv. It is now 2 weeks later and it is going back to the store. The colors are great, but the picture is terrible. It is incredibly grainy, the pixels are HUGE and everything is very blocky. Watching any sports (main reason i bought the tv) is absolutely dreadful because the picture is so distorted, the players are just a big blur. I emailed toshiba support and they said that the pixelation was normal, not good. I went through every possible setting to find some clarity by custom tuning to no avail. You can not turn off the internal speaker, another downfall. I'm gonna get a samsung 27" tv instead as the picture on it is incredibly clear and not blocky. Heads up with this tv if you are planning on buying it.
