It will have a wiring and schematic diagram, if that helps. I can't determine if that will help you fix the problem, but I wanted to at least give you that information.
I have noticed some fan noise coming from my set. I found that there are two fans for replacement at samsungparts.com and decided I would replace both. The website also offers a Service Manual for my set and my question is will the Service Manual instruct me how to replace the fans.
