HDHR4-2US Losing Signal Randomly

Post by Kainlan »

I've had two HDHR4-2US for years and they've worked fine. About a month ago I updated their firmware to the latest beta firmware and now they seem to randomly lose their signals, both tuner less blink green back and forth and I have to restart the devices to get any channels tuned again.

Device ids are 1045F904 and 10461B56

Thanks for enabling diagnostic logging. Can you please let me know when you next experience the problem so I can check the logs at that time.

I actually happened about 40 mins ago on 1045F904 I don't remember if I turned diagnostics on before or after I restarted it that time though.

1045F904 is in the broken state right now and has been for the last like 2 hours. I haven't restarted it yet. I can't really leave it on the channel for 5 minutes. Plex fails to find and if I try the hdhomerun app it tried to tune and then switches to the other device when it fails.

Can you please run the HDHomeRun app and let it sit on a live TV channel for 5 minutes.

Edit: I just noticed a write error realating to the live TV buffer on your Samsung device. This isn't the problem you are talking about in this thread but will cause the channel to stop playing after a while. Can you please check how much free space this Samsung device has available.

I did that just now, I unplugged the other hdhomerun so it would attempt to use the one in the broken state. It sits for about 15 seconds and then says "Unable to play channel: No Video Data Communication Error."

If you have a few minutes can you please jump on IRC chat... it will be easier to work interactively to run some checks:

Thanks for jumping on IRC - I think I have enough information to try to reproduce the problem tomorrow.
