I had my KVT-715 hooked up and it worked. Later though it would turn on and as soon as i would click the SRC and go to tuner, DVD or anything it would turn off. I have to unplug a fuse (controls the doomlights etc) and it would turn back on, but it will do the same thing if i click on the src and try playing a CD. I can go through and look at the menu and all that stuff and it will stay on... If anyone has any ideas or experience any help would be appreciated. Thanks
