Hi I installed a SW64 to my dish intallation in order to get 3 Sats feeds. My problem is that I have a 722 dual tuner which was previously set on dual mode to second tv using the diplexers just using one cable to send back the signal. The thing is that the SW64 works great but I cant see the picture on the 2nd TV now. My previous installations was SW21 and SW21x setup that worked with the diplexers. Any help on how to make the SW64 configuration with the backfeed of the diplexers? I read that maybe I need to connect the diplexers on the cable that have the power inserter but I am worried that this could fry my switch or diplexers. Maybe a good diagram could help. Thanks in advance.
