ANSWERED: Troubleshooting TV No Picture, Black or Blue Screen
Troubleshooting Steps
- Make sure all power cables are plugged into working power outlets for the TV and for your X1 TV Box.
- Hand-tighten all cable connections to make sure they're not loose.
- If using an HDMI cable to connect the X1 TV Box to the TV, confirm that it’s plugged into the proper locations.
- Power on both the TV and the X1 TV Box.
- Confirm that the TV is set to the proper input.
- If you've completed the steps above and there’s still no picture:
- Press Exit > Exit > Exit > 720 on your Xfinity remote. This should bring the picture back by setting the resolution to 720.
- You can then change to a different resolution by pressing the xfinity button on your remote and selecting the gear icon (Settings) > Device Settings > Video Display and choosing the resolution you want.
