PKG3.915.0139NAB System Update

I don't see it as available yet for download or more information in the Support section, but my XBR-65X850C had an update waiting for me this morning (10.03.17). 


No information was available as to what it addressed (or what the new version was) when selecting 'More Details', but since I've experienced - let's say - less than stellar performance from the set since installing the previous update (ending in 0137NAB), I took an unceremonious leap of faith, restarted the TV and let it do its thing.


The result is new version PKG3.915.0139NAB.  I've searched high and low for information on this version and can find nothing.  I can tell you this information from Settings / About:


Android security patch level:

August 1, 2017






SVP4KDTV15_UC-user 6.0.1 MMB29V.S41 3.915 release-keys


What they leave in, what they take out - I don't know.  Perhaps it is just me, but the set does appear to be a bit snappier responding to the remote for nav, selection and volume control.  YMMV.


Thus far, no problems, but inquiring minds like mine would really like to know if this is just a security update, or if it is designed to address some of the shortcomings of the previous build & possibly add (or, in the case of Twitter) remove features...

Update came through on one of my XBR55X850D’s but not the second one. So far so good 😊.

I see this update is also available for the XBR55X810C.


Anyone try it out yet and can give some feedback? I have held back on any updates for quite some time now based on all the issues users have been reporting.


Maybe this one is the 'golden' release this fixes these issues?

Hi Jay -


Thanks for the info but you are repeating what is already available online.


I am looking for end-user feedback on the stability/reliabiilty of this release. Previous releases have been a bit of a train wreck with slowness/crashing issues. Until I hear some good reports I am staying put on an older, stable version.

Re: PKG3.915.0139NAB System Update

After installing this update today Version PKG3.915NAB my YouTube APP could not log in. I called Sony Support only for them to tell me that my XBR-55X850C is OUT OF WARRNTY and they would not assist in this update they sent to my TV that messed it up aformentioned.Every time I tried to log into my Youtube APP it showed an error.


Alas the tech lady finally did send me an email with general non-specific instructions to correct.


Later I went into the Google play store APP and signed in there then updated all APPS. Thereafter everything functioned ok. Why could'nt the Sony rep just tell me this since she said it was a known issue...

Re: PKG3.915.0139NAB System Update

After applying the Oct 2017 update,  there seems to be degradation of the picture quality.  


Loss of sharpness, detail

Colors somewhat more washed out

More artifacts (particularly in motion content)


It's a little hard to describe because some content still looks good, but other content does not.  Almost like the upscaling is not working correctly.


There was another post on different version of the update (PKG6.2669.0070LAA) that has a very good description.


Anyone else experiencing the same issue?


I have called and chated with Sony support, but can't get to someone knowledgable enough to discuss the issue.


Thanks for any info or suggestion,
