Both TV boxes recently started randomly going out, getting stuck in reboot loop

Internet service is fine, including streaming Xfinity TV programs. But TV service has recently stopped working reliably, within the last week or so

- two boxes: main X1 box in living room, secondary box (smaller, don't know the model type) in office

Sometimes TV is working fine. Other times I turn on the TV and it just shows the "Welcome. Bienvenido. Bienvenue.". So it seems to be randomly rebooting at times when I'm not watching.

A few times, I've been watching a show, and it seems to start glitching, then the box reboots after 20-30 seconds.

The office box sometimes shows error RDK-03036. I have power-cycled both boxes multiple times, doesn't seem to make a difference.

To my knowledge, nothing has changed with the hardware or cabling within the house. No issues with internet, as mentioned -- consistently getting good speeds.

Thank you for reaching out to us @user_o7eagt! Have you had a chance to check the coaxial connections? For troubleshooting purposes could you please check that the coaxial connections going into the boxes and the wall outlets the boxes are connected to are finger tight? If there is a splitter between any of the boxes and the wall outlet they’re connected to, we will want to make sure all the splitters connections are finger tight.

 

With all the connections finger tight, we can send signals using our awesome Xfinity app. This article here has steps on how to use the Xfinity app to send troubleshooting signals to the boxes.

I have verified that all of the connections into the boxes are finger tight. I also verified that the junction box where the line comes into the house is finger tight. I have power cycled both boxes multiple times, including leaving them unplugged for several minutes.

Internet service (on the same coax cable coming into the house continues to work without any issues, it is just the cable service / X1 platform.
