Good luck! You will have to be persistant.

I don't see anyone else with a US version talking about 1026 firmware. Now that downloaded that (this is probably a dumb question) will I not be able to apply 1024.8 if I get it from Samsung? What about the logic update?
Thanks!

Probably can't go back to 1024.8 if you install 1026.0

I can verify that at least for my 51D8000 1026.0 did not update the logic board. However, the separate logic update process, which I did after 1026, was successful..

i got stuck on:
9. Start ruSamsungTVCommunicator, it should automatically find your TV and display a box with several tabs.
10. Open the Fernbedienung tab

what were is ruSamsungTVCommunicator?
After turning the TV back on, nothing appeard
post #906 of 1615
ruSamsungTVCommunicator is a service remote emulator which will unlock the logic upgrade function for D7000 and lower models. You must download and install it first, then connect to the TV via a router or directly through ethernet cable. The download link and instructions for using it are in the first post.

Zoyd, please explain the difference between FW update 1024.8 and ALTERNATE 1024.8 that you posted?

I'm not aware of an alternate 1024.8 The 1st post has the 1024.8 (For D8000 owners) that was sent out by Samsung to several owners and the logic board .bin files from that FW in case the FW doesn't update your logic board.

edit: nevermind, you mean the alternate link. nothing, they are the same.

That's what I was wondering. Thanks!! I'm going to give it a go.

Zoyd, After I downloaded both files I found the first one contains a folder "MACOSX" which the alternate does not. ?????????

creating a zip archive on a mac usually does that so he probably created the first zip on something else than a mac

I don't mean to go too off topic here but I know the level of talent in this thread is pretty high. Is it normal to have a ton of green pixels on black/dark backgrounds when you get right up to the screen? I notice this on all modes for my 59D8000. Here's the interesting thing; on my 58C6500 I could get rid of them if I turned on Movie mode. Any help is greatly appreciated!

Not unusual for very dark scenes when the display is trying to reproduce the first few levels above black you will get a lot of dither, mostly greenish. It goes away if you lower brightness but then you lose that detail, it shouldn't be visible from normal viewing distance. As long as what is supposed to be black (letter box bars for example) has no dither you are ok.

Awesome thanks for the quick reply.

Updated and fBR is COMPLETELY GONE from what I can tell!

Now.... does anyone think that this update to the logic board will put any stress on the panel that maybe Samsung wasn't intending? Hence the hush hush about the firmware update and not releasing it to the wild? I know I over think things but I can't help but feel like my TV is doing something that they originally didn't intend for it to do.

Also without any tool to measure, I swear blacks look deeper with 1026 and the 11-11-04 logic.... Almost too black (crushed). I need more time with it.

Appreciate any thoughts on this!

I got the 1019.5 USB stick from Samsung for my PN51D550. I put it in the USB1 slot and tried to run the update, but it said something like no update file found after I tried to update via USB. I tried it a few times in both USB slots but it didn't work. Any idea what might be the issue?
post #918 of 1615

Did you verify that the directory structure on the stick looks like this:

\\T-GAP4AUSC\\image

if not you need to extract the image folder from what they sent you and put it into the top level T-GAP4AUSC folder

I just took a look at what's on the USB they sent me. I've got:

\\T-MST5AUSC\\image

Any idea why this is different? Do you think if I change the name of the folder then it will work?

If you read the first post you'll notice that T-MST5AUSC firmware is for the D6500,D6900,D7000 displays so it looks like they sent you the wrong one. Download the correct one from the same post.

PN59D6500 here, FW 1015, I get through everything I have in bold but then I cannot find any SVC to navigate to - Any Ideas?

Quote:


D7000,6900,6500,550 procedure
(Activating the service menu will reset the USER menu settings so write those down)
1. Download this file.
2. Extract file for your model from list below and rename it to LOGIC.bin - Note: If you have "show extensions" turned off in windows rename the file LOGIC
3. Place on stick in folder PDP_LOGIC
4. Turn on TV and attach stick to USB 1
5. Press mute+7+3+7+enter
6. Check Logic SW version
7. Check panel version (DS or DF)
8. Turn off TV and turn back on
9. Start ruSamsungTVCommunicator, it should automatically find your TV and display a box with several tabs.
10. Open the Fernbedienung tab
11. On the emulator, hit the Info button and then the Factory button to get into the Service Menu

12. Navigate to SVC with your regular remote and select it
13. Navigate to Logic USB D/L and select it
14. Right arrow to initiate flash (no turning back here)
15. "Upgrading" will be displayed if the TV accepted the file and this takes a minute or so and then the TV reboots.
16. Recheck Logic SW version.

After info+factory you should see the service menu items as follows:

Option
Control
SVC
Expert
ADC/WB
Advanced

Thanks so much for the help. They must have picked the wrong USB because the envelope's label was clearly marked with V1019.5. I'll download as you said and run with it. Thanks a lot!
post #924 of 1615
Thanks guys for the advice, I joined just to say thanks.My D550 was driving me mad so I fixed it with the logic board update as it is an Australian model.I was having trouble with the remote emulator program and I found one that is a little bit more english friendly.
post #925 of 1615
Hi all,

I applied the fix earlier today to my Samsung D550 and can confirm that the brightness pops are now gone. However, the display immediately developed areas of red snow, largely at the top of screen but also sporadically throughout the image. This appears to be affected somewhat by the colours on the screen. I have tried various settings but nothing helps.

Any suggestions anyone? The TV is only 3 months old and will still be covered by warranty. The retailer has their own repair service, so may just need to bite the bullet and have this looked at.

I should also add that I am in the UK so firmware for the TV has been sorely lacking.

@Boomzzilla - thanks for the report and good to hear!

@McCoops - thanks for the report and bummer.

Is this snow present on a totally black screen?
Have you calibrated your display with a test disk for contrast/brightness?
Can you remove the snow by lowering brightness?
Do you see the snow from normal viewing distance?

green snow usually results from brightness set too high, I think this is the first mention of red snow.
post #927 of 1615
No, the snow is only visible during bright scenes or white objects in the background.

I've tried all brightness/contrast settings to no avail. No calibration disk, however I consider myself to be fairly competent in this respect (I waste hours getting the balance right on my Projector and TV's)

The snow is very visible from normal viewing as it's very thick. Before the fix was applied, this was not evident.

I'm aware a primary cause of red snow is erratic voltage, for which Samsung acknowledged, but I've ruled this out due to never having previous issues.

Is it red or magenta? In bright scenes if you see magenta snow (especially in the upper right quadrant) that means the green sub-pixel is misfiring. Did you notice a decrease in black level after the update? If so it looks like it decreased your panel voltages.

edit: Forgot to ask, what size panel and how many hours on it?
post #929 of 1615
It could be magenta although it depends on the colours in the image as to how dark/light it is..

There was a definite drop, but black levels did seem fine (possibly due to the fact there was no pop). I had to restore my settings though and the balance seemed slightly off colour wise, so I would agree that the voltage may have dropped.

Interestingly, I've had the TV unplugged for a short while and everything has improved slightly, though the snow is still there.

TV is 51" and I would say no more than 300 hours.

magenta on white background means green misfires.

It's not the voltage levels if you have a 51" because those can't be changed in firmware, only via analog adjustments on the boards for this size display. If you notice that's it's worse when the set is first turned on relative to a good warming up period then it is definitely related to the timing signals though. The only way to correct that is to replace the logic board to restore original timing signals or open up the back and adjust the reset level timing (not for novices).
