Can you please try rescanning for the channels? Here's how to do so:
40.0: DISH Remote > [SAT] > [MENU] > Settings > OTA Channels > Scan
5x.x: DISH Remote > [SAT] > [HOME] > [HOME] > Settings > OTA Channels > Scan
Once the scan is complete, select "Save".
To continue working towards a resolution I do need to access your account. Can you please send me a PM with your account number and security code?
