Looks like I have the same problem as many others with the Emerson 32 inch TV. I bought it at Walmart less than a year ago and it was little used as it is in a summer house.
When we went up this weekend it worked for a day and then just died. The company doesn't stand behind it's products and make any sort of repair expensive, inconvenient and long (up to a month or more).
I would never buy another Emerson product nor any electronics from Walmart. Given the pervasiveness of these complaints Walmart should also get involved with their vendor to make it right.
