I'm in the market for a HDTV but after reading the various manufacturers forums here. It would apper that Samsung models have nothing but problems . !! Faulty colour wheels, smudges, flickering brightness levels etc etc . I understand the forums lean to problems with sets , but compared with other mnfctrs forums Samsung has more than its fair share...or am I wrong.??? Are there any positive comments to be made re the sets or should I cross them off my list ???
