Dimming problem every time subtitles appear on 32PFL9705

[Sofus]

The 9000 series TVs are faaaar better than other/ordinary TVs. Even with local dimming off (just don't sit in a completely darkened room or have ambilight on). Philips never advertise(d) the feature as perfect. But we can still hope it'll be fixed, because it is annoying in greyish scenes.

They do advertise there 'LED PRO' series with the deepest blacks, and that's what you want for 4000€, but it's not what you get...

Thanks Vilnix for showing us the problem once more. Philips?... Are you listening?...

It's especially helpful as this shows that even the 9955 has this problem. Apparently the complete 2010 LED Pro range (32/40/46PFL9705 & 58PFL9955), plus the 2011 58PFL9956 have the Subtitle Dimming PROBLEM! Yes it is a PROBLEM Philips, in case you didn't realize...

I'm just starting to wonder WHY there are still no reports from either 2009 LED Pro 40/46/52PFL9704 or 2011 40/52PFL9606 & 46PFL9706 owners? As these are all using the same LED Pro dimming system, they should in principle have the same problem. Or in case they don't, Philips should know how they did it and fix ours... I'm waiting!...

Hi there,

I accidentally saw this topic while searching for another issue.
The problem exists for smaller models too.
I wave a 40PFL7605H/12 purchased on April 2011
Unfortunately it is one of many other things that do not work ok on Philips TVs...

Regards

Hi George,

thanks for letting us know. It is, however, not surprising that you're experiencing the same on your PFL7605, as the 7605 only has Global Dimming, so it is kinda logical that the whole screen reacts when bright subtitles appear.
For the 9000 series, on the other hand, it is simply unnecessary and, quite frankly, a very weird way of making a true Local Dimming system more Global in nature!?... WHY!!!???...

What are your settings ali? Another problem I have noticed seems to relate to the Christmas tree light problem, where in a scene with fog, mist, low light and a moving object, the backlight goes crazy and seems as if it cannot make up its mind, whether to dim or light, but I have only noticed it when this type of picture is displayed. Plus on another note, my top row ambilight is lighting up very blue, I have it set to cool white for bias lighting purposes but the top row seems to be bluer than the sides, very distracting!

The problem is there on 46PFL9706T. I actually came to this thread because of another backlight related problem but I can see what you describe on your video. I suppose I will be keeping the Dynamic Backlight Off.

It's kind of sad that I can't find a TV without a some kind of eye-catching problem. The Bravia I bought in 2007 might have been only HD Ready and not have great blacks, but when I had it, I could concentrate on the content instead of the TV's quirks.

The Edge-Lit Samsung I bought after that the Bravia had actually the opposite problem that bugged me. With global dimming I was actually bugged by subs going dark when the rest of the scene was black.

For those interested:
The reason I came to this thread was because I was watching Grey's Anatomy. In a scene with a woman lying still in bed the bottom and top rows were dimming intermittently. However, just now the problems seems to have solved itself, maybe because I turned the TV off and on.

Thanks bugmenot for being the first with a 46PFL9706 to report this problem! It doesn't surprise me...

By the way, just to keep things as clear as possible for us and Philips, when you say:

"The problem is there on 46PFL9706T. [...] I can see what you describe on your video."

Could you tell me what it is exactly that you see and using which video, as more videos were posted in this thread over time?...

Thanks again in advance!

And Philips!?... Does this mean anything to you?... Please let us know you are there.

I've this issue with my 52PFL9606. I tried 0.98 and the latest 0.99 firmwares, both gives the same result.

Default Cinema Mod uses "Dynamic Backlight" as disabled. So you cannot see this issue, and you cannot use Local Dimming feature of your high end TV.

I'm also using Cinema Mod, but I set "Dynamic Backlight" to standart manually without any other modfication in this mod. I can observe this issue with this settings.

Thanks for letting us know! I added both the 40" and the 52" PFL9606 to the opening post.
I think it is safe to say by now that no solution is to be expected anymore for any of the series suffering from these problems... Why?... If only I knew.
