Flex 4K Won't Detect All Channels - Captain Klunk

Post by Captain Klunk »

Hi, I had a very similar thing happen to my Flex 4k last night. I recently updated to the latest firmware and shortly after I noticed a huge drop in the signal strength across all channels. My other two HDHomeruns did not have the same issue and I also moved one of the working ones to the same antenna connection as the Flex 4k and it had no issues. I went ahead and turned on send diagnostic information and did a channel scan with all three of my devices including the Flex 4k. The ID of my Flex 4k is 10A21DAF. I also opened a support ticket #252894 but have not heard back from support yet. Unfortunately my device is out of warranty, so I'm not sure what my options are. Any chance this could be a similar issue to the one originally posted here?

Thanks for enabling "send diagnostic information" and running a channel scan. It looks like a hardware fault. Drop a quick email to support and they will help... it will need to be returned so we can repair or replace.
