Terrestrial picture randomly breaking up - reboot receiver fixes it
- Status
Just updated to 5 1 002, drivers unchanged at 30/Sept - no improvement :-(
I've done that for you
No response received from your support organisation, but I've had 5 1 003 loaded for 24 hours now (after having to follow the recovery process).
This has driver dated 2017-10-20 which again exibits the same issue on DVB-T A, it looks to be temperature related - I don't see the error until the processor temp is reported at 59c (never looked at this on warmer days).
Over to WoS for comment.

The processor temperature on my ET10K is currently 73C.

No, but I thought you were saying that the problem was related to the processor temperature, and 59C is not particularly high.
Mine has single hybrid dvb-c/t2 tuners.
That is Octagon support email address, not my support.
@ goRT, please give a step by step how to replicate. Any particular channels cause your issue more?
Have you fully checked your coax feeds, antenna etc? Are you using in F connectors with F Type to RF adapters by any chance? Have you double checked all RF connectors? Any RF splitters? Any distribution system in your Terrestrial feed?

Hi, I don't think it's processor temp that's the issue, but that's the only reading available on the SF4008 and was something I noticed as a potential cause as the issue didn't occur straight away after yesterday's flash.
Why give that out to me then???
OK, I'll go back over all the data points I've posted in this thread.
No issues on the 2nd DVB-T tuner on the hybrid which is in slot one (as you know there's only a single coax feed into the SF4008 DVB-T card)
No issues when plugging the coax directly into the TV
No issues on the TV when routed via the SF4008 card when experiencing issues on tuner A.
Brand new coax cables used, as well as existing ones originally used. No F type connectors.
Used an attenuator as previously recommended, but that made no difference.
Sometimes the issue doesn't occur directly after a reboot but may take a few mins to appear, yesterday after flashing the new release the issue didn't present for 15-20 mins - when the box had warmed up.
Today it took a few mins to appear.
Disabling and re-enabling tuner a may fix the problem for a short while, but then it re-occurs within minutes.
When returning out of the playlist view the short pause may cause the issue to disappear for a few seconds/mins.
I NEVER have the issue on tuner b
I used to have the issues with DVB-S on tuner c, but a driver update several months ago remediated that.
I did try ATV at one point when that was getting more frequent driver updates, but that made things a lot worse (I wasn't getting the issues and someone asked me to test!)
No splitters in my apartment, but I am on a building distribution system of some sort (I have no access to that, and didn't see any disclaimers relating to this in the sale documentation)
I'm not the only one with this issue as I'm not the OP, I'm just the boring person who repeatedly provides data as requested and rigorously posts up each time an update is available and drivers update.
So you could report the issue direct to Octagon, imho its either a driver or signal issue, but try following.
1) Disconnect power and remove lid.
2) If you have a tuner in slot B remove it.
3) Move your Terrestrial tuner into slot B.
Iirc if you have one twin tuner module in either slot it will be detected as a twin tuner, but I might be wrong.
Re-test with the tuner in slot b.
Hi,
Yes, I have a DVB-S in slot 2 (no hard drive, 1gb ethernet to a server).
So I have tested as requested:
1. swapped the DVB-T into slot 2 (leaving slot 1 empty) which allows both DVB-T tuners to be access
2. recorded 4 HD channels concurrently (split across tuner a and b) whilst watching a 5th on tuner a
3. waited 45 minutes for this to warm the box up to 60c
No issues observed (but it's hard to prove a negative)
4. Returned box to standard state (DVB-T in slot 1, DVB-S in slot 2)
5. Again started 4 HD DVB-T recordings
6. Waited for the pixelation to start (CPU temp showing as 59c)
So the card functions correctly in slot 2, but not in slot 1.
What further PD do you require?
Thanks
One more test, put the twin sat tuner in slot 1 and the hybrid in slot 2, then retest as tuner a will be forced in slot 2.

Hi,
So I removed the DVB-S card and ran the box with 4 HD recordings for 90 mins.
The picture breaks up, but cancelling the recordings allows the picture to recover, it isn't stable but it does recover unlike in the normal config.
I've then swapped the DVB-S card into slot 1 (but I only have a single sat feed) and the DVB-T card into slot 2 and have been unable to replicate the picture breakups (but obviously only a single T tuner is available in this config).
Thanks

Hi, I've experienced a similar problem (broken up terrestrial reception after random time, even though the signal is OK). Did anyone already find any cause and solution? It looks like a badly driven tuner (software issue). Thanks.
My configuration is purely terrestrial (DUAL DVB-T2/C tuner in slot A, slot B is empty). Octagon SF4008 + OpenATV 6.1.

I found putting the DVB-T in the second slot fixed the issue (altough I can't then use DVB-S and have 2T tuners) - can you test that and update us please.
Thanks
