Missing frames on USB HDD playback

mad_cyril — Mon, 27 Jul 2020 10:36:39 GMT

When playing back recordings made on a USB HDD we get missing frames where the screen goes black for a split second. This can be every few minutes or every few seconds. This only happens on playback, not when watching live TV.

Hi mad_cyril,

You could try getting in touch with Sony Support about this to see what they say.

Thanks,
Pascale

I have same problem.

My HDD is the same make as yours, 1TB version, only difference is my TV is 49XF9005.

Didn't have this problem on Android 7, it only started to happen since it was upgraded to Android 8.

I think the issue only effects HD recordings playback. SD plays back ok. It doesn't matter if the recording took place back on Android 7, the play back is missing frames.

I know of others on forums who have the same problem.

Thanks for reporting this, mad_cyril.

I thought that this was a fault with my USB3 128GB flash drive until I tried another USB2.0 flash drive and got the same problem and then saw this thread.

I have seen the flashing black screen problem on both BBCHD and ITVHD, but yesterday, as a test, I set a recording of Dempsey and Makepeace on ITV4 SD and can confirm that it seemed to be ok, so it indeed looks like a problem with HD channels only as reported earlier.

Me too. I'm using a Seagate SSD 1TB on a 49XG9005. Seems to be HD content playback only too. Any luck with a solution yet?

Handyandyxf9005 — Sun, 16 Aug 2020 12:04:44 GMT

I'm going through stuff with Sony support at the moment but currently no solution.

Tried the following -

Factory reset.

Pulling plug and waiting 2 mins before re-powering.

Clear cache.

Re-turne of signal.

Haven't been able to try a clean/new drive as I don't have a spare.

I would like to try deregister the drive, full format on a PC and then register it again for recording and see if that works but don't want to lose all my recordings.

Anyone willing to try?

Thanks for that. Hope one of those works. Hate the idea of doing a factory reset or reformatting the drive and losing all my recordings. Very drastic but worth it if it works.

None of things support have suggested to try has fixed the problem, for me anyway.

A factory reset did not cause me to lose my recordings.

Deregister of HDD for recording will cause me to lose all recordings.

Has everyone contacted Sony support of the issue? Please do as the more that report it the more chance of getting a fix.

I would hate to go through a factory reset process and lose all my settings as part of a fix that almost certainly wouldn't work, particularly since I have already done this once as part of another support ticket opened with Sony.

I (and others) have established that it appears to be only a problem on HD channels.

I have tried two different 128GB USB sticks that have exhibited the same problem on HD channels.

A test recording of Dempsey and Makepeace on ITV4 (SD) appears to be fine, looking at the first five minutes (Enjoyable at the time when I was little but I wouldn't want to watch all of that now! :))

I am over 1 hour and 30minutes of the way through a Film4 (SD) recording of 'Roman J. Israel Esq' and there hasn't been a single frame missed.

I have already reported at least two other unnecessary and annoying faults to Sony since buying my XG83 television a couple of months ago. I will leave this to others to report as I don't want to add to my growing pile of personal Sony support tickets, at present.

Thankfully, I have decent functioning five year old Panasonic PVR that can record HD without problems, anyway. It just would be nice to have the back up of being able to record a third HD broadcast at the same time for when the PVR is already fully in use.

My TV is the XF9005. Different TV, same issue so to me it sounds Android 8/software related.

If I find/get a fix I'll be sure to report here.

Thanks to all for your comments. Unfortunately no solution as yet but I will report it to Sony Support. Yes it is only on HD channels for me too. Is anyone using an extension for the USB cable and if so have you tried with or without the extension?

Re: Missing frames on USB HDD playback

Handyandyxf9005 — Sun, 16 Aug 2020 21:25:09 GMT

I'm not using an extension cable on my USB drive. Just the original cable that it came with. It's just long enough to connect to TV, run down the back of the tv leg and allow the drive to sit flat.

Ive got the same issue on both my 55xf9005 and on my 65xf9005. Ive tried a factory reset on the 55, 2 different hard drives and one ssd but the issue persists. Mine were also fine on android 7. Im running the latest firmware but each time ive upgraded the fault has remained. Its so annoying that ive gone back to using my humax pvr.

Hello everyone,

I'd recommend contacting Sony support about this as the more reports are received of an issue, the more data is collected and the closer a solution is.

One thing to keep in mind is that Sony don't recommend using a USB stick for recording, so expect to be asked to try an actual USB HDD before a case can be investigated officially.

Some other basics to cover:

-Update the TV to the latest software by checking the Sony website

-Check the signal quality (usually found in the Help menu)

-Make sure the HDD is registered on the TV
-Confirm the issue happens even after a factory reset

Brand new KD-49XH8196 here. It does this on mine with a Seagate 1tb plugged in...Random black flashes. Annoying!

anyone heard anything? Cheers.

Hi Nicko001. I reported it to Sony Support but have not heard anything back from them. However, I have not had this problem recently so finger crossed it may have sorted itself.

Something I do now avoid, because I think it may cause problems, is watching a program from the start whilst it is still in the process of recording. If you record the whole program then watch it after it has finished recording it is all fine. But if you start watching it from the start whilst it is still recording the end, then I think this may give issues such as pixilating and the missing frames.

I have also had another issue where all my recorded programs disappeared for a few days. I couldn't record anything new and the tv was prompting me to re-register the HDD (which I didn't do). After a few days the programs all re-appeared and it is all working again.

HDD recording on our old Sony TV was faultless all the years we had it but this new TV seems to have various issues with this function.

Thanks Cyril, glad things have improved a bit for you!

For me though, I’m pretty sure i had not started to watch any of the affected shows while it was still recording. I’ll steer clear of recording HD for a bit as an experiment.

maybe it was a bad idea to go for Android TV? A bit on the flakey side!

I get this problem with the KD-49XH9505 which I've just purchased. I've tried a Samsung T5 1TB USB 3.1 Gen 2 SSD and a hard disc connected to the HDD USB port on the TV. I've also tried formatting the SSD in both exFAT and NTFS, changing MotionFlow to Auto and Off, Film mode to off and have rebooted the TV a number of times. I've also checked the latest software is installed and the signal quality is 100%.

When playing back recordings I get random missing frames where the screen goes black for a split second. This can be every few minutes or every few seconds. This only happens on playback, not when watching live TV and I believe it only affects HD recordings although I haven't watched enough SD recordings to be sure of this point.

I will report the problem to Sony Support and to the Sony dealer I bought the TV from.

Please let us know if you find out anything. Cheers!

Will certainly let you know if I do make any progress.

However, I'm beginning to think I may need to buy an HD PVR. But this would be an unexpected expense and a disappointment which would dent my confidence in the quality of Sony products.
