Report "I have a new protron remote for a Spectronicq 7 inch dvd player. I can't get it to work. Has a new 3.31 battery but none of the buttons energize it. I don't see an on and off switch. Can you give any hints or should I just return it? Could it be that the IR receiver on the dvd player is bad: How can I determine which unit may be bad. The dvd player works o.k"
