Tuning adapter not working

Sorry, I meant to note that they gave been working just fine for the past few months that I have had them. It's been a week or so now that I have noticed I'm not getting my channels and that the light is off. I've even tried unplugging and plugging back in.

Which City (Market) and Motorola or Cisco Tuning Adapter?

Las Vegas and it's a Cisco STA1520

Cox Las Vegas is relatively new to SDV, and is still working out the bugs and adjusting their SDV channels, patience may be required.  The green light should always be either ON or Blinking if it is OFF try pressing and holding the button on the front.

Here is a troubleshooting guide I put together, see if it helps.

Hi Rawonders, 

The link Bryaninphx provided contains great troubleshooting info. Thank you, Bryan!

Whenever the TiVo no longer shows channels that were previously working, we recommend the following steps:

1. Unplug the USB Cable
2. Reboot the Tuning Adapter
3. When the Tuning Adapter is back online with a solid green LED, plug in the USB cable
4. The TiVo will go through the Acquiring Channel process

Sometimes it is necessary to power the Tuning Adapter on and off to get the LED to go solid. Also, you may need to go into the TiVo settings and run the channel lineup update if it doesn't run automatically.

Please let us know if you are able to restore all your channels!
