Yes you have a couple of bulbs burnt out. To change here is what it takes. Remove your radio by pushing the little tabs on each side,a dime will get them pushed back enough to make them releace. Un plug the unit from the back side
Oh Yea make sure you have your radio code handy when replacing the system or she won't come on, you will at that time enter you code # then hit auto and she will start working.
After taking the unit out remove the screws on the sides that hold the face on, the knobs on the front of unit will pry off and then a few snap connects around the unit will let the front cover off. now you should be looking at the circut board holding the bulbs, there are three or four little metal tabs spaced out around the board that are bent sideways holding this board to the units frame. Take needle nose and straighten these tabs up and the circut board will release. Now you can get to the back of the board and give the bulb holders a 1/4 turn and they will release. Now the fun starts
I had to get my good reading glasses out for this,you take the bulbs out of the holders by unwinding the wire on the holders then reversing this procedure when installing the new bulbs back. You will also have to cut the ends of these bulbs on reinstalling the new parts. Bulbs came from Radio Shack
Part # 272-1092 micro lamp 12 volt. Good luck about an hour and a half.
