I have a Kenwwod KDC-215-S cd player that's always worked very well...........Now i turn it on and the faceplate lights don't come on......the player works fine but no lights............i heard the bulbs in the faceplate might be bad so i took the faceplate apart and there are two bulbs facing each other attached to a cicuit board.....could one of these be bad?.....and how the he// am i going to replace when they are attached to a circuit board?.......what a pain....i have never seen anything like this before, any help is appreciated....
