All I want to do is play some dvd's and my player will play the dvd movie for 15 maybe 20 minutes then all of a sudden it will shut off and will not stay on. I have to unplug it for 30 minutes and it will do it all over again. It says E1 or E2 and the front where the clock is. I have everything pluged in right. I do I cancel the E1 or E2 mode and make it go back to bing mormal.
