while watching the tv, the tv automatically switches to dvd mode and will not switch back until i manually turn off the tv and switch it back on and if i turn the tv back on too fast, it will continue to do so. Thers time that the tv has to be left off for a few days in order for it to work. My remote no longer works to the tv so basically i just use my cable remote but ths issue is stressing me out. can any1 help me or should i just trash it??
