so i got my sony xav-60 hooked up and it worked for 20 mins perfectly fine. after that 20 mins i put in a dvd to test it out. it had audio but no video. it said “video blocked for your safety”. so i took the dvd out after 5 mins and when i took it out the lcd display screen went blank and now wont go back on at all. i havent touched any wires at all. it just stopped working. if i press the eject button for the disc it goes in and out and it beeps through the speakers. just no visual on the screen. WHAT IS THE PROBLEM???? PLEASE help.
