I have a Dish Network VIP722 – I need help sharing the signal from TV1/TV2 to an additional third tv. I don’t know what all I would need to purchase or really how to go about doing this, so if someone could give me some info that would be great if this is even possible. Also, I do not have the option of running wires, I live in a condo and all wires for the satellite were pre-installed in the walls of my home. Would this be possible to do without running any more wires? I have enclosed pictures of the back of my receiver of what all is there currently, and also what is downstairs in my garage where all of the COAX from all TVS meet. Any help would be appreciated.
From the posts here I see everyone is very helpful. I am going to give a step by step guide.
Cabling
1. The final picture to post is of a diplexer (I am speaking of the diplexer that is not in the same room as the receiver) goto this diplexer
2. Locate the connection labeled VHF/UHF and disconect it (the cable that was just disconected was the TV2 cable)
3. Connect a short cable to the VHF/UHF connection
4. Connect Splitter to the other end of the short cable
5. Connect TV2 cable to the Splitter (now TV2 is back up and running)
6. Connect TV3 cable to the Splitter
7 Cabling is complete
Modulation Background
TVs can be set to Air or Cable modulation. An Air modulated TV can not be tunned to a channel over 69. A cable modulated TV can tune to channels over 73.
A. Cable TVs can be set in the TV menu to Cable or Air
B. Some old TVs are Air only
C. If one TV is set to Air and the other cable just because you set them both to channel 60 does not mean they will get the same signal
Modulation settings (For old Air only TVs easiest way is to set everything to Air)
1. On the receiver goto menu 6-1-5 and see what mode the receiver is on and change it to Air channel 60 ( you can also enable TV1 modulation to channel 58 if you like)
2. Goto TV 2 if TV 2 can goto channel 73 or higher enter the TV menu and change the TV to Air Mode
3. Tune TV2 to 60 and you have a picture ( also if you enable TV1 modulation you will have a picture on 58 as well)
4. If you cant tune the TV to the correct channel run a channel scan in the TVs menu.
5. Goto TV3 and repeat steps 2-4
6. Modulation Complete
