Brand new 55 Q9FN, terrible panel quality

Hi, 

 

I've just switched from a 49 MU7000 to a 55 Q9FN and was giddy with excitement about finally owning a top end TV. 

 

Unfortunately, I've either received a dud or there's an inherent problem with the tech; for HDR (and even SDR content), the screen goes /incredibly/ dark during dark scenes. We aren't talking perfect QLED blacks here; all detail is lost, UNLESS I leave a white menu screen up. 20180627_195814.jpg

 As you can see from the photos. Annoyingly, I'm also using an S9 to take the photos so it does a better job of amplifying the incoming light, but believe me when I say it's even worse than the TV is showing. I would estimate that the unlit picture is displaying at <10 nits. 

 

I ascribed this to either a problem with local dimming or eco mode, but modifying both of those settings made no difference. It's making using the tv for anything other than bright content unusable, and I didn't honestly expect a £3000 TV to be notably worse than a £700 TV. 

 

Please advise. 

 

P.S: Why have Samsung removed the ability to change audio languages when playing from a USB source? All of my movies are playing in Italian or Portuguese with no way to change it.

Yes - noticed that one too - but it seems theirs was resolved in a past firmware update... ours however still seem to be exhibiting the issue on more recent firmware so I’m not sure it’s the same issue (or maybe they reintroduced that bug in a newer firmware release?)

I had a 65KS9500 which had a really good bright picture. But it would not do scheduled recording and was told a known issue. Samsung changed it for the Q9F and what a disappointment. HDR was dull, it had really bad banding and was a far let down compared to the KS. I sent pictures to Samsung, and they said they were within spec! I did get a full refund from Samsung. On the q9fn HDR programs should make you say wow, like the KS did. If it does not then suspect it may be an issue, and always report to your retailer as a fault. You pay a lot of money for a premium TV and you should be stunning.

The Q9FN is much better than the KS9500, it has double the peak brightness and also full backlight, so no edge light like the KS9500. My 55" Q9FN has an incredible picture, HDR is stunning with most sources I viewed so far. However that dark scene issue is definitely a fault that needs to be fixed urgently.

The KS9500 is back lit and was very good, but would not do scheduled recording. The replacement Q9F was edge lit and awful, and got sent back. My friend has a Hinsense 6800 and that was brighter. It must have been a faulty panel, but Samsung said it was within spec. They still agreed to refund me.

Ah, Q9F you wrote, that is the older model? Thought you refered to the Q9FN. Yes, that should be edge lit then. And oh yes, I also realise now the KS9500 is back lit. Sorry, my bad. 😉

Actually the info on the web is confusing about the Q9F, I found some pages saying it has full back light.

The 2017 Q9F is edge lit. The 2018 Q9FN is backlit, FALD.  The thing is some are finding it does not do as advertised. I must say the KS9500 was a brill picture and I was very dissapointed with the Q9F.

I had the ks9500 which was very good,  HDR was brilliant but it would not do scheduled recording and no iPlayer 4k or hlg,  and no smart connect. Samsung replaced it with the Q9F and normal SD was good but HDR was awful,  dull and terrible banding. Films with letter box had a dark shadow around the letter box,  it was like looking through a tube. I sent Samsung pictures and they said it was within spec!  They did give me a full refund though. I will find it hard to to trust them in the future.

I had the same exact problem, 

 

go to the eco settings and turn off "Detection of ambient light"

That fixed it for me.
