When I turn my t.v. on I get a picture for 1 second, and then it goes black.i however have audio.I thought the problem was the cable box, so i replaced it with an h.d.t.v. new cable box, and still no picture.the cable guy said it was definetly a problem wth my t.v.I have a one year limited warranty on it, and purchased it in april 2010.Wallmart explained that the warranty has only a 90 return policy, which has lapsed.They told me 2 contact the manufacturer, which is more dead ends.what might the problem be with my t.v.?
My 46inch Sanyo t.v. has a black screen, no picture.?
