First post, but didn't see this issue scanning back 6 months. Call w/ Dish support was worthless.
I have 1 Hopper w/ 3 Joeys that are all exhibiting the same issue. After working fine for over 6 months, all Joeys show linked to the Hopper, pull current guide info, and show correct tuner usage. When selecting a channel from the guide, I get a "must switch to Live Mode" msg and then get a blank/black screen. When selecting a recorded show from the DVR, I get a blank/black screen. Banner information is correct and the tuner information shows the Joey using the selected channel.
Walked through troubleshooting with Dish support, show have verified config, re-set both the Hopper and Joeys. Changed connection and currently have 1 Joey connected via coax, 1 hardwired Ethernet and 1 wireless Ethernet. I've tried bring the Joeys up separately after resets (to test for connectivity issue). I'm at a loss.
Hopper is running S334
Joeys are running S286
Any help would be greatly appreciated.
