I have a Kenwwod KDC-215-S cd player that's always worked very well... Now I turn it on and the faceplate lights in the middle rectangular box don't come on... the player works fine... 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... these don't light up but many lights around the OUTSIDE still light up.. any help is appreciated...
