I need to disconnect the fan in my HDTV receiver but need detailed instructions on the process. I've tried simply unplugging the fan but the receiver won't come on that way. It looks like I need to fool it. Does anyone know how to do this or have any other options. I want to keep the current fan intact should I have to reinstall it to send the receiver back for any warranty work. I have already sent the receiver in once about the fan noise and other problems only to get it back slightly quieter. I can hear the fan over my TV when listening at low volume. This is unacceptable.
