I recently puchased this model of TV for my parents at a Costco store. My parents satelite is out and they opted to watch a dvd. Well this tv is a lot different from the one that they used to have. On the old one the had to just chanel down to Aux in order to watch a dvd. On the new tv my mother claims that when she goes to input, it will flash on the screen and then flash off very quickly. It doesnt stay up long enough to be able to input down to the correct selection or that is what she is claiming anyways. Please respond back as quickly as possible. Thank you.
