Our radio / cd has decided to die ... all the lights and functions are working, but no sound. It did the same thing about 10 months age, and after about 3 week I replaced a tail light bulb and (coincidently) the radio worked again!!! It has just happened again, I have dismantled it, but nothing obvious (and I don't need to replace a lamp). Any ideas as to the problem would be appreciated, or perhaps we should say thanks for14 years service and buy a new one....
