CISCO 1642HDC box will not reset

I have two HD receivers in different rooms the that are connected to a signal splitter and 1st receiver went off-line yesterday morning. My wife was watching TV on 2nd receiver at same time with no problem.  I checked my connections first and swapped connections which allowed a good reset for 1st receiver.  So the 2nd receiver (the one that was working fine yesterday) will not reset and logically thinking I have a bad end on a cable connection at the splitter.  However, after multiple reset attempts and connection swapping at the splitter the 2nd receiver will not reset and hangs at the TV screen message " Downloading Initial Application".  I'm at my wits end on this troubleshooting episode.  I guess I need to check signal strength with a VOM at the mail line coming in to house.
