I had the same probl with a phillips43" Lcd. I bought it at walmart. I called customer service with asurion. They had me cycle the tv a few times . They had me send the set in for repair. Not much you can do to these tvs today. They either work, oe they need to be replaced. If your set is under a month old and purchased at walmart. Go online and insure it with asurion. The refunded the price of the set plus tax. I then added a few more bucks bit upgreaded frpm a 43"to 55" with a new ploicy. Now when this tv goes, I will upgrade to a 65".
