Yeah it is bad...
I kinda had it with (this instance of) this TV. I mean, I really like the design, picture quality and rest, but then it DOES need to work...
This morning I've counted that it has been - in total - more or less a month at the repairs. Three times.. I'm thinking this one is fubar...
I will try to make any video's and post them.
I think the dimming issue has to do with the new panel they've put in my TV. It did improve the viewing angle (it used to be terrible if you would move only a couple degrees from the centre, now only the colours get a bit less when looking at it at a very large angle), but the changes in backlight intensity has been increased and I don't like that...
To be continued....

First of all congrats with your 100th post (I'm almost there... )
I couldn't find the number, I did noticed that I could see a print (electronics) on the top. Didn't thought that was there, but then again, never looked that good at the back-top of the TV...
Is the number the same as the 12NC number found in the '123654 menu'?
I did managed to get some video's. Only got SkyDrive, so the links are down here:
Admin desktop fade:
Because of the auto camera settings, the light is faded sometimes, which makes some things a bit worse than they are, but the darkflower IS actually that bad. The backlight IS fading slowly from light to dark or vice versa.
The admin stuff is far worse 'in real life': you reallly see a dark cloud following the dialog.
This new screen that is replaced during the repair may have a better viewing angle (see also the end of the subtitle), but I rather have the old (worse) viewing angle, but enjoy the great backlight experience than what I have now.
When I came home I continued installing my PC and again the picture was gone. This time it was more gone than available, so I called support, which said that it is within 3months of the repair (reapair guarantee), so I could/should contact the repair service and discuss with them how to handle this situation.
And now the screen is on for an hour without one drop so far (knock on wood)....
It should start with LKxxxxxxx.

Just to rule things out: how are Contrast, Brightness, Perfect Contrast, Colour Enhancement and Gamma set?...

I would love to check it again, but - allas - now the TV almost died completely: The backlight manages to get past the "Philips" logo and then dies. No tricks to fix this so I cannot check.

But I do think you're right that the LEDs just get too much intensity.
Now I'm back with the small Sharp from the bedroom again...
For Sinterklaas a little belated,
for Christmas a bit too snappy,
for Philips a present they waited
for, so I hope they're happy!

My new test is... once again... a scene from a movie, this time one from the 80's called LadyHawke. It's a nice fantasy adventure, full of somewhat darker scenes, so I guess you know what happened... Throughout the ENTIRE movie, every time a subtitle appeared or disappeared again, the brightness of the screen went down or up.
Not only did this happen in the scenes we all have come to fear by now: dark or misty ones. It even happened in SNOW scenes!... And in those scenes it wasn't just bad, it was TERRIBLE!
The video fragment I uploaded contains such a scene. Look at the brightness of the snow itself or look at the sky and... weep!... Weep that a tv of this class can look SO INCREDIBLY BAD!!!...
Please Philips, my final plea this year, give us a Christmas present too!...
The snowy backgrounds are prime examples of the picture flashing in brightness but I've seen worse especially with anime sources. As I said before the effect is worse when there is a homogeneous colored background, in your example snow. Other examples are fog or even office interiors and so on. When light gray office walls are present with people talking in the foreground the slow head movement suffices to make the walls blink in brightness. Very annoying indeed and the reason why in many cases I simply disable the dynamic backlight.

I've updated my TV with the firmware ver.140.46 (32pfl9705h).
I've checked the movie sample that Freddy has posted on the forum (DarkLadyHawke2 and SubtitleDimming) and the dimming problem is almost undetectable. There are some little screen luminosity variation but the whole bad effect has gone away.
Philips did a very good job!
Now I hope that Philips will solve the "film credits" (end of a movie) dimming problem.
...and thanks to Freddy!

I must agree to that!
Let's see if there are more nice things in the upcoming firmware releases!
I am running .25 firmware, and I will only upgrade if this has been fixed. How does the overall picture quality rate in the new firmware release? And as for the post credits, that is another problem which I don't like, plus the opening scene in Star Wars with the floating text in space is just horrible to watch with this problem. Would anyone mind trying the Blu-ray and reporting back? Thanks! I take it that you guys have the dynamic backlight setting to one of the options other than off?
let me try to explain ;-)
The credits appear from the bottom to the top. And the text lines are smaller than the LED segments. So, if one text line moves from one LED segment row to the next above, the backlight dimming becomes lighter/darker... some kind of slowly blinking.
Is this the "film credit dimming problem"?
freddy and tech-uk
i can tell you the pictuer of all updates after 0.25 is no more inky that is a same with 0.46
