Hey friends I need your help. My Symphonic TV doesn't have a remote. I was able to watch dvd before I hooked up cable. After I added cable and all the channels I cannot watch dvd anymore. I even tried to unhook the cable line and hook back the dvd the same way it was before but it wouldn't change to video or dvd mode. I even tried many different channels to no avail. Is there a way I can change it back and forth without a remote? Thanks
