Inquiry (采购产品): Re: Inquiry Good Morning, this is Mrs. Diosa Balucio Bande, a chemistry teacher at hogan High School in vallejo unified school district. I have a concern about the overhead projector that I am using. I beleive it is a new overhead projector( Model 120 SN: 521001D40104390).Several times already that I'd been replacing the bulb, it does work after I changed the bulb but then after 1 or days of using it, it's broken again. I guess there is something with it. It is just frustrating because I need it everyday in class. I can't teach with out. Please help me out how to fix this problem. Your help on this matter is highly appreciated. Thank you very much. **** Hidden Message ***** Diosa Bande 850 Rosewood Avenue Vallejo, CA 94591 USA Company: Hogan High School Title: Teacher E-mail: di2hb@yahoo.com **** Hidden Message ***** di2hb@yahoo.com
