Question

i have a 05 jvc tv 32 inch . I lost my remote temporarily-used the menu on the actual TV to set a timer for the TV to go OFF-turned it on this AM and now i have half of my screen filled with this overlay . its kind of transparent . like the screen that comes up for tv controls , but its just black . i change channels and it goes away for two seconds then its back covering the bottom half of my screen-
