When you were able to remove the RJ45 (phone) connector, you disabled the On Command box comms with the TV. Because the TV in your room was not locked out (the installer can chose to turn that setting on or off) you were able to access the inputs. However, those inputs, and even the TV buttons themselves, are part of the initial setup. Normally they are locked out because, and don't take this wrong, we nor the hotels want guest "messing" with the TV's. Whenever a TV is disconnected, reprogrammed, unlocked, etc., very rarely does the panel get put back into its original mode. In turn, the next guest will call the front desk with a problem, and the hotel engineering staff has to come fix the problem, or, if it is right after a new installation, call my company to complain we did not do our jobs. I hope you can understand my reluctance to share all the programming "secrets" or codes to the general public. In searching for past problems with a certain model panel, I came across this forum and thread, and thought I could help out by explaining which sites are most likely accessible, and which ones its not even worth trying to mess with (i.e. the LodgeNet sites without boxes and the sites with HD). In that regard, I am more than happy to share my knowledge, but, the Hotels are my customer, and they have to be my main responsibility.
Climbing down off my soapbox, I can say more and more hotels are realizing the necessity of providing access to the aux inputs. The biggest challenge is on the sites that have PPV and/or HD, as the PPV or HD interface (required because the HD channels are encrypted, so something has to tell the TV to un-encrypt the signal), be it a box or internal card, takes control of the TV and effectively blocks access to or even completely negates the internal menus settings.
Again, please forgive me not giving out our codes, but I will be happy to answer or help in any other way I can.
