What error message? What receiver do you have and what TV?

HDMI H1001 error unable to display video receiver is Cisco ISB7005 and TV is Toshiba

We'd be happy to help you get the video working properly on your receiver, @Jmenensez.

We recommend, that you follow these steps to help you restore your video:

• Restart your U-verse receiver(s) by holding down the POWER button for ten seconds, then pressing again to restart. (This takes 5-8 minutes and will impact any DVR recordings in progress.)
• Restart your Wi-Fi gateway by removing the power cord for two minutes then plugging it back in (will interrupt AT&T service).
• Check for snug and secure video cables connecting your TV, gateway, and receiver.

Please reach back out if these steps do not work, so we can order you a replacement receiver.
