I have purchased a digital tuner for my TV's in my motor home. No problem with the installation. Works great. It comes in on channel 3. Prior to connecting the digital, my cable came in on channel 3 and when I wanted to watch satellite TV I would change it with the TV remote AV button which changed it to AV1. AV 2 was blank and cable was back on regular channels. Now the digital works but no cable when I shut off the digital box. Same for the rear TV set. If I disconnect the coax from the digital box and go back to the original connection, the cable works fine. I have DISH as my satellite service.
Any advice would be appreciated.

You do not say what brand Digital TV Converter Box you are using. You need to confirm that the Digital TV Converter Box you are using has the Analog Pass-through option. The Analog Pass-through option allows signals to Pass-through the Digital TV Converter Box when it is in the off position (also known as standby mode on some boxes). This is why I highly recommend the Zinwell ZAT-970A Digital to Analog TV Converter Box as it has the Analog Pass-through option and it is also very highly rated by its owners. If the box you have does not have the Pass-through option, then the cable signal cannot Pass-through the box.
It also sounds like you are using a cable box from your
