In my temporary care for investigation I have a relative's FVP-4000T and FVP-5000T. The reported problem with the 4000 was overheating, whereas the 5000 exhibits this losing-the-guide/no-programme-information problem. After checking the software was up to date and effecting a manual rescan of...
It's exactly a year since I first installed CF when I was trying to resolve a problem which turned out to be due to a faulty aerial amp PSU. It seems I was very unlucky that this caused all manner of problems. Pleased to report that the PVR has been working faultlessly for 5 months now after...
Main PVR has been working faultlessly since applying the system flush a week ago, so today I reinstalled Humax 1.03.12. Thread also retitled (from After 5 Months with CF, Removing for a While).
The CF was installed over the weekend of 12/13 Nov 2023 and problems first logged in my 15 Nov post, including the "melt-down" we had that evening (https://hummy.tv/forum/threads/faulty-preamp-psu-caused-humax-reception-problems-on-some-muxes.11086/post-170227). This was followed-up a couple of...
Well... It looks like the system flush and the re-creation of the R/W flash filesystems has done the trick. I won't make any further changes (like installing the Humax FW) until the PVR has been fault-free for at least a week and we can think about returning it to full service.
Big thanks to...
So the order should be:
RMA
Reboot
Standard Firmware
System Flush
(I omitted step 3 because I wanted to see if the system flush fixed the fault without making any other changes at the same time.)
Thanks. My reference for this work has been the Remove Modified Firmware Wiki; the glossary entry explains the origin of the term RMA (as I was manager, electronic maintenance at C4 for 7 years I was aware of this).
The further and better particulars are welcome. In #64 you referred to...
An update now that I've performed a system flush on the faulty PVR in a moment, but first some questions arising:
Every time the faulty PVR started yesterday (apart from once), after the display had shown the CF version it showed first ENTERING, then RMA, then MODE. This message triplet...
I did think about creating a list of affected/unaffected channels when the fault is present (maybe this will reveal something); TPTV and Sky News are reliable indicators however and since Saturday, when I first tried the RMA process and chased the fault away (for the first time in weeks) I've...
Just to round-off today's observations, after I posted #75, ie around 4.10pm I switched the PVR on again; again it said ENTERING, RMA, MODE - but this time the fault had returned; TPTV and Sky News both causing freeze-and-reboots after about a minute of moving pictures. Fault hadn't been...
I think not, as we've not had this problem with the spare PVR. This has been in use for some two weeks now during the evenings which is when we used to get maybe a couple of instances of picture break-up each night when on the faulty PVR - and then only recently (previous few weeks). I...
No confusion here. You quoted from #60 which was the status as at Saturday afternoon when I made the decision not to swap the power boards and before I installed the CF on the faulty PVR to allow me to try the RMA process. What does enabling the RMA process under Diagnostics/set RMA mode...
Thanks for clarifying. Have switched the PVR on again this lunchtime and still behaving itself in this interim state with FW (allegedly) removed from HDD but remaining in flash.
Yes, although we're in Woking we receive from Crystal Palace. Historically (ie since analogue switch-off) reception...
Further testing (details below) has proved this was no coincidence. It's also proved this fault is not a hardware one - so at least I don't have to bother changing all those caps. The RMA process has proved problematic so I guess my only hope now is a system flush (which I've not yet tried)...
Problem returned after reinstalling Humax 1.03.12 following completion of the RMA process. Plan today was to repeat RMA process but after starting-up PVR there were at least three freeze-and-reboots - then none. Currently monitoring but will repeat the RMA process a few times later, then maybe...
We've been successfully hopping between the spare HDR-Fox T2 and the faulty PVR for ten days now. The spare is working faultlessly and the faulty one continues its regular picture-freeze-and-auto-reboot on the troublesome services. Both units are running Humax 1.03.12 (ie not CF). I decided...
To progress investigation of this issue, we’re now using a spare HDR-Fox T2 (same one that helped out when investigating Start Up Fails When HDD Connected | hummy.tv) between 18:00 and 22:00 (my wife being the principal user) and the faulty one outside of these hours (when it’s my turn). The...
Am I right to draw a distinction between a hardware MPeg decoder and one that is a software process? If the SoC's AV processor is a hardware implementation it would make sense to start changing caps around this block. I recall seeing a block schematic of a similar chip (and a pin-out?)...
Tried again and confirmed. I changed service 30s after first pictures and will experiment with other periods. Will also try one or more of our spare units today. This problem has evolved and affected channels are now unwatchable due to the constant reboots, which was definitely not the case a...
