I just set up my new Monster HTS5100. Last night everything was fine. Today I fire up the system and the "Clean Power On" light is no longer illuminated. No matter what I do the "Clean Power" indicator light won't come on. All other indicator light appear to be functioning properly. Has anyone else run into this? Monster has no published info on their web site and the manual does not address troubleshooting for this. Thank you in advance.
