My DWT 1304 Duraband 13"TV has been sitting up for about two months and yeterday I turned it on to connect it to a DVD player that I just purchased and the screen only showed snowy. I disconnected the TV from the same plug of the DVD and tested it with other devices in the home. I can not find the AUX screen.
As you have not had an answer so far I suggest that you put this question in the Portable TV section as this is for DTT (Digital Terrestrial TV) Receiver section.
When you do this try to say how you connected the DVD player i.e. what cables to what sockets.
