Vizio installer menu for VU32L

Question

Re your post: http://www.fixya.com/support/r156665-vizio_factory_menuI
was just told by Vizio support that there is no "installer" menu on the
Vizio VU32L. I'm not an installer by trade, but I suspect that that
assertion is untrue. Any chance you could share your knowledge with me? More specifically, my problem is that the TV has an orange "standby" light on the front panel that lights up my bedroom at night. I wish to turn it off when the TV is not in use. Vizio support was wholly unhelpful.Drew
