Insignia Lcd I Brought An Insignia 22 Inch LCD HDTV From Best Buy Yesterday, Should I Be Worried?

I brought an Insignia 22 inch LCD HDTV from Best Buy yesterday, should I be worried? - insignia lcd

I went to Best Buy yesterday looking for an HDTV, and I saw a reasonable 22 "Insignia LCD at a price when I bought it, but after I got home and no more research, I found many mixed reviews when it really worried about the reliability or someone who has been actually received and not broken down quickly?
