Arrived on site at 9:55 am
Located the TV with the stated issue.  Tv #4 has signal but not maching channel as stated
Jumped on the Bridge
Guy (After Work Bar GM) arrived on site
Explain to him what I suppose to do while on site
Told him I'm about to reboot the Matrix for the Bar Tv's
Rebooted the Matrix in the Network room
Disconnecred and reconnected HDMI connection to Matrix at TV
Spoke with Jeremy on the Bridge and explained to him what I had done but told him I would provide details in my report
TV #4 is back but still with incorrect channel
Tested TV #8 using the Samsung remote to change channel (which seems to control the rest of the TV's which I change channel and other TV's on the Matrix) except for TV #4
Decide to use the Comcast remote and TV #4 respond to switching channels
Match the channel of TV #4 with TV #8 (again, that TV seems to control the Matrix Channels) and all TV's are now on the same channel
Did a few more test and I can get get all Matrix TV's on the same channel included TV #4
Ask Guy to test it himself and he is able to have TV #4 matching the rest of the other Matrix TV's using a Samsung remote (used the one labelled Matrix)
Talked with Guy and explain to him that different TV's have various imput (Matrix connection/some with Apple TV's and some with Comcast boxes) and that Nuranne and I worked on a document that clarify which TV's has what specific device connected to each TV's along with the HDMI imputs and I suggested if Nuranne can email Guy so they have the TV's connection nformation on site (information is not accessible to me at this time) which could be useful when needed. 
Ask if Guy had any additional questions and if we was comfortable with the process and he said he was
Ask Jeremy if he had any more questions and he said no so I left the Bridge
Left the site
