Does your 2011 Samsung "D" plasma have brightness pops? - Page 64

For those of us who did not get the OPTIMIZATION step I am wanting to see if maybe adjusting settings to your current settings corrects the issue with the right firmware installed.

Thanks.

1. With TV on press mute + 7 +3 +7 + enter
2. Post your Logic SW Version and Logic SW Checksum from the display
3. Turn TV off and then on to get rid of menu

Sinku, ours is the same
Red, I'd like to see yours, since neither of ours has been successful

Any other PN64D8000 that have had successful updates, please try to post this information if you can

Martin: Hi, thanks for reaching out to Samsung tech support. How can I help you today?
Me: Thank you. I have a PN64D550 that is experiencing brighness fluctuations/pops. I was on 1018.1 and have been sent firmware to upgrade to 1019.5 which fixes the problem or is advertised to.
Me: Anyway, I did the upgrade and my understanding that in addition to the upgrade an OPTIMIZATION step occurs or is supposed to. The OPTIMIZATION actually corrects the issue.
Me: When I upgraded last night to 1019.5 - no OPTIMIZATION screen appeared and now the issue is still there.
Me: Can you show me how to force the optimization or do you need to send a service tech to the house to perform this?
Martin: Does this happen on all inputs (like DVD and cable box)?
Me: yes I am watching with HDMI from CABLE and from PS3.
Me: I somehow think something didn't toggle right and the optimizaiton step was fixed. On the AVSForum, everyone who is getting this firmware fix says that the firmware seems to have corrected the issue IF the OPTIMIZATION step occurs. Not everyone is gettting this though.
Me: I mean OPTIMIZATION step was skipped - not fixed.
Me: Someone else reported that 1018.1 upgraded to 1019.5 like me with same model did not work and Samsung is dispatching a tech to do something.
Martin: Just to confirm, have you got any USB from the Samsung with the firmware?
Me: yes i have the firmware file T-MST4AUSC 1019.5
Me: version info SWU_T-MST4AUSC_001019_I01_ES000_111202
Martin: Okay, I am checking the issue.
Me: Thank you.
Martin: I will be right with you.
Martin: Please hold on for a few more minutes, I am still working on the issue.
Me: No Problem.
Martin: Thank you.
Martin: I will file a service request so that current firmware will be sent to you.
Me: I thought 1019.5 WAS the current firmware.
Me: That's what the TV set now says on screen.
Martin: Please let me know your full name, contact number, email address, shipping address and serial number of the unit so that I can file the ticket.
Me: So what are you sending me if I have the current release?
Martin: Thank you for waiting. I'll be with you in just a moment.
Martin: We will send two USB drives, one for roll back to the previous version and one is for latest version.
Me: Which version will it roll back too? Can you explain please?
Martin: It will roll back to previous version.
Me: which version number? I was on 1018.1 before I did the update.
Martin: Yes, it will roll back to that.
Me: If you roll me back to 1018.1 and then reapply 1019.5 - that is no different than what I did already.
Martin: Now it will resolve the issue.
Me: Can you please explain to me how that will resolve the issue if I go back to the very release I was on?
Martin: I'm sorry for the delay. I'll be right with you.
Me: Thanks.
Martin: Please wait for a while I am filing the request.
Martin: You will get it with in 7 to 14 business days.
Me: But, what about my question? I don't understand why rolling back to the version last night only to re-apply the same upgrade will fix the problem?
Martin: Generally this fix the issue.
Me: So doing this will cause the OPTIMIZATON step to kick in?
Me: So you are saying that your documentation is stating that this is the fix for the Optimization step to kick in?
Martin: Yes, you are correct.
Me: If this doesn't fix the problem can CHAT help me or should I just call a technician for warranty repair?
Martin: It should fix the issue.
Me: But if it doesn't?
Martin: then you contact technician for warranty repair.

Anyone ELSE have luck with rollback and upgrading??

What does this mean Nesbo? Looks like I have the same as you.

Okay, so i decided to try the fix on my 59d550 plasma, btw, its a plasma purchased in mexico and it worked so no probs there.
- i turned off the tv when plugged the usb
- Turned on the tv and the firmware was detected (update via usb)
- The install began, took 2 minutes first, turned off, then optimization process a minute more or less.

I have my doubts about the black levels, i can swear they were deeper but again its just me being paranoid and obsesive compulsive.

I checked the hockey game i recorded, and the pops were still there. So i checked two films i saw how the shadow areas turned bright all of a sudden.
First film had two issues, checked those, eliminated
Second film, Midnight in Paris, theres a shot of the Notredame cathedral and it tilts down to the protagonist, he is sitting in a bench. Theres obviously an exposure adjustment from the cinematographer, but the plasma used to pop brightness in a weird way.
I checked this out, and that weird adjustment in brightness was still there, the tree leaves all of a sudden turn from a dark green to a very light green.

This is where it gets weird, if i turn black level off, that pop is gone. But if i turn black level anywhwre from dark-darker-darkest, that pop will appear.

I turned black level off, and checked the hockey game again, most of the issues are gone, i can still see some drops or somethig weird when the flashes happen, but mostly is gone.

Again,i have doubts about the black levels, seemed to rise, but i just dont know.i have a light meter (conematographers sekonic lightmeter), but i dont even know how to measure the black levels on a screen.

Also, if i turn dynamic contrast on, that weird pop is gone.
Black level in darker, and cinemasmooth on, and the pop appears.


I hope i didnt lose any deep level, or a 3d feature over this fix.

She said the tech WILL be familiar with my situation, and that they do have a part in stock that should fix this. I asked her what that part is out of curiosity, and she said "main board". So hopefully it gets fixed Monday!

Will keep you all updated.

TGIF!

Measurements taken with my i1D2 so absolute values may be off but the changes are real and accurate:

1. Measured rise in black bars of Casablanca clip linked in FBr discussion thread: 0.015 - 0.045 ftL (delta=0.03 ftL) (previous delta was 0.009 ftL)
2. Measured rise in black bars of another test clip I use (Cowboys and Aliens): 0.015 - 0030 ftL (delta=0.015 ftL)

The rises are less abrupt but bigger. We need someone with a meter to test a normal upgrade.
