My advice would be to first try cleaning the laser lens, either with a commercial CD lens cleaning disk or a Q-Tip dampened with rubbing alcohol. If this doesn't work the problem could be with a capacitor, or the laser might need replacing. Can't give you too much technical detail here. With regard to a service facility I can recommend Atlantic Systems in Hanover, MA. You can google them for a phone number, address, etc. They're the official Northeastern regional service center for B&O. Good luck.
