i purchased a cd/tape combo offline only to have the theftlock on--not a problem to get unlocked, but the display went out before i could have the theftlock undone. so, i disassembled the entire unit and found three burnt out led bulbs. my question is, what voltage are they and can i purchase any lcd bulb for the replacement? i bought what radio shack suggested for the bulbs. i am considering gutting out the old factory tape deck and using those bulbs, but i don't really want to do that. any suggestions!!
