Weird issue between X1 Cable Box and Vizio E62x-C2
Later that day, we had a storm that knocked out the cable box for some time. When it came back, it repeatedly gave a 'resolution not supported' error on the TV screen. The read-out of the current resolution at the top of the screen is constantly changing. The cable box was able to communicate with the TV via coaxial, though, so it works right now, just not in HD.
I know the two are compatible, though, since it worked when the technician left. I've looked around for solutions, though, and most focus on setting the box to output in a specific resolution -- I've tried every resolution it offers, though, with no success. I've tried it on every HD input on the TV as well.
Possibly worth noting: the cable that was plugged into the cable box (or the port it's plugged into) doesn't seem to be working anymore, either. The cable box was plugged into HDMI3 -- the cable box no longer connects to the TV via HDMI through any of the HDMI cords, but, other devices that work with other HDMI cords won't work with HDMI3 either. So right now, neither the cable box nor HDMI3 work, and they were plugged together and working fine when the storm hit. I would try switching the cable to isolate whether the issue is the current HDMI3 cord or the TV's HDMI3 input, but the TV's mounted to the wall, so it's not easy to change.
So, to recap:
- Thursday noon, cable box outputs HDMI to TV via HDMI3 just fine.
- Storm hits. Cable box is knocked out.
- After storm, cable box can no longer connect to TV through HDMI1, HDMI2, or HDMI3.
- After storm, no devices can connect to TV through HDMI3.
- Other devices still connect fine through HDMI1 and HDMI2, except the cable box.
- Cable box still connects fine to TV via coaxial.
Based on this, it seems like the storm damaged that specific connection, hurting both HDMI-Out from the box and the HDMI3 cord specifically. But that also feels weird.
Also worth noting: during a storm a few months ago, the network card on my computer was fried. So it does seem our incoming cable connection might be prone to surges (electrician is coming to address that in the morning).
So while I think I've reasoned through the error, I was wondering if anyone with more experience can tell me if my reasoning is way off.
