Wednesday we had a Comcast service outage for several hours. When service was finally restored, the main X1 DVR box shows "no signal" to the TV. The 2nd smaller box works just fine, can access all recordings, new scheduled recordings are being made on the DVR, it's just not sending a signal to the TV.
I've swapped HDMI cables and used a brand new one plus a known good one from another device. I've ruled out bad HDMI ports by hooking up another HDMI device, a Roku, and it worked fine. I've made sure no connections are loose. I've even hooked up a different TV, the one that was on the 2nd smaller box so I know it's getting a signal, and it also shows "no signal" from the DVR box.
Because the 2nd box is working fine, is it safe to assume that it has to be the X1 DVR box that's defective? That it can't be any external connection coming to the house, right?
I know everything is super busy and slow because of the virus. When I called Wednesday evening, I was promised an escalated tech support person would give me a call back on Thursday. I checked with chat Friday noon and was told I was scheduled for a Friday evening call back. Saturday afternoon and still nothing.
I'd like to just take the X1 DVR to a Comcast Store and swap it out myself, but I want to confirm that it must be a defective box and nothing else that would require a service call. And how can I be sure the store will have another X1 box to give me, are they guaranteed to have stock? I can't find individual phone numbers per store location to call and check.
