Ive had this TV less than 2 yrs. This week it started looking a little dark in top rt corner at turn on. Then after a few min it would b fine. Then I turn it on an the screen is black but could hear sound n hear the channel change when I used remote. Called dynex this am and they had me turn off TV n unplug...hold power button for 1 min then plug in and power on. now nothing no sound no picture just blue light. They said they can search for the receipt n if its within warrenty its covered. If not I'm beat? Apparently many are experiencing same or similar problem just after warrenty expired. Grrrrr HELP
