0. Set the TV onto an unused source so you have a black or blue screen. This makes reading the menu easier in later steps.
1. Turn the TV off.
2. On the remote, press MUTE, 1, 8, 2, POWER
3. The TV will turn on into service mode. It takes a few seconds after powering on to display the service menu.
4. Using the arrow buttons on the remote, go down to Option Byte and press Enter.
5. Arrow down to "Lvds Tx Fmt" and press Enter.
6. Using the right and left arrow buttons, change the setting. Mine was set to JEIDA. Setting it to VESA fixed things.
7. Press Menu to exit.
8. Turn the TV off to apply the changes.


Also, check the info from the link I posted (below) to make sure that a few other settings in Option Byte are correct for your tv.

Thanks to you and this forum for posting this information! I went to the Samsung website and found firmware update for my LN-T4061F....downloaded it onto a flash drive, stuck it in the back of my flat screen and....*&^%*&^!###!!!!!.

Bad thing was....I was doing all this at 11:30PM before going to bed and knew the wife would be getting up in the morning to watch the weather. I remembered this website and this forum and found your fix...never had to call Samsung and listen to their BS about not updating firmware - I was up and going in a matter of minutes (after a few tries with the remote to get the service screen to come up). Again....TY..TY...TY.

And for my money - if I would've found this post to begin with, I probably WOULD NOT have updated my firmware; I didn't notice any difference to be honest and the sickness in my stomach was definitely NOT worth it! Save yourself the grief..."If it ain't broke, don't fix it."

Beware the firmware update still on the Samsung website for this model still garbles the colors. Thank God and all you gurus out there for this website.

I wish I had found this site before I like the others installed the samsung software on my LN-T4061F set. I was able to restore operation with the changes listed however I seem to have lost something that I can not seem to adjust like I had set before software install. I have checked the settings listed and those in the tech setup are as listed. Set just does not seem to have the HD POP that it had before it is hard to put into words the difference. Anyone have any advice something I could look at settings or such. Set does not look bad it just that maybe not quiet as good a picture. But maybe its just me. Thanks for any advice and be warned do not upgrade your set unless you are specifically told to do so.

I know what you mean about the "HD Pop". Something seems to be off. The crispness looks to be degraded a bit. I wish there was a reset function to set the tv back to the original factory condition including the firmware release.

Thanks to all who have posted their experiences with the firmware "upgrade" issues. I have had the same EXACT experience with Samsung customer service as well. It's obvious there is a big disconnect between what the firmware upgrades are meant for and what the consumer perceives them to be.

Like I said, do a search and you should be able to solve this.

Hi,

I have the same issue, but only on the NTSC analog channels. All digital channels ( QAM and HDMI) are fine. Is that the same problem and solution in your posting?

I just want to say thank you...
I did pretty much what everyone else has done and dealt with the rude service people ("don't upgrade/update!!!!"). Well that isn't what Beyonce sings about...
The service woman laughed at that("let me upgrade...upgrade").
I told her everything looked like the movie "Tron"...and that we have just become accustomed to upgrading/updating...which makes sense...

anyway...I had to register just to thank everyone in this forum.
I called samsung and then they told me they would order a service call.
I called the service center to ask what the turnaround time is...beginning of Jan...2-3 weeks...
Holey Sheits...my wife hadn't woken up yet (she just walked downstairs right now) and I didn't want to hear about the TV not working...so I googled everything I could. found this forum...

wow...followed the changes posted by gfunkdave...and within a minute picture was back to normal.

now why don't they walk people through this...I am under warranty...and the call would have been free...
so they would lose money.
now for those not under warranty....they can make money but why not walk someone through the steps and free up service guys for real problems...
thanks again.

After connecting my new Blu-ray player, I began experiencing the HDMI signal loss issue and occassional pink or green flashes (2007 LN-T4061F - out of warranty btw). The Samsung guy on the cnet forum recommended that I update the firmware. I downloaded and installed the latest firmware without issue (updated from 1009 to 1037).

So far haven't seen the symptoms previously mentioned (pink flashes, green flashes, signal drop). To be honest though, I have only played on DVD so far, so it's not exactly a rigorous test.

Since upgrading the firmware though, unfortunately I have a worse problem! The picture quality has degraded substantially. At first I thought I might be imagining a difference just because I updated the firmware, but I am not. I noticed right away while watching various tv programs (both standard and HD) and then when I changed source to watch a DVD, the Blu-ray start up screen, which had previously been displaying in perfectly smooth gradients, is now showing very obvious banding. It's a similar to displaying a 32-bit image on a computer when the display is set to 16-bit. Also now if I adjust my picture settings, it only maintains them for a while, and then seems to reset them. This did not happen before.

By the way, I have read through the other posts and have already checked the service menu settings since updating the firmware, and they were already set correctly.

Is there any way to address this issue? I would rather somehow rollback to the previous firmware if it would restore my picture, and just live with the occasional signal drop.

Any advice?

I'm confused. I have a Samsung LN-T4661F. I downloaded the firmware update, did it all just like the .pdf manual instructs and now no power, no picture, no sound. Bought the tv in 8/07 (of course, now 2 months out of warranty). Samsung says I should have never tried to "update" the firmware and I'm on my own. Help.

Many thanks to all of you and especially gfunkdave for his instructions on how to fix the problem.

The Internet is a great place to get information and this time was no exception. It seems like Samsung would fix their firmware to not have this problem as many people seem to be experiencing it.

I also have a BlueRay player BD-P2500 and it has found new firmware several times in the month since I bought it and I experienced no problems updating that firmware so though that this would be equally as trouble-free. Boy was I wrong. If not for this forum, I would have probably had to pay for a service call just to set this one setting to the correct value.

Again, thanks

Hi i have a LN-T4061 lcd tv. My mainboard i knew was going. I was losing channels. So i bought a used board off ebay. Samsung Board 0749 TULIP/SAFFRON BN41-00843D FP-T5084.

After installing this, turining tv on colors were bad.
I went into service mode and changed it from VESA to JEIDA, and the colors are back to normal. Why is it the opposite from what is mentioned here in this thread?

I had the same board in there thinking i was getting a updated one, assuming i had a BN41-00843A, turns out i had a BN41-00843D TULIP/SAFFRON already. But why would i have to change anything in service mode then?

Anyways i pick up my channels again, but the local hd ones are choppy, i cant figure out why. All i can think of if theres any other settings i need to set in service mode.

Any Ideas?

GFUNKDAVE -- Just in case you are still following this at times. Thanks! Same issue as the rest. Same sucky Samsung support tech skills. Ran your update and all is fixed. Called Samsung to tell them to update their tech logs for there sake and their customers.
Thanks again

- GFunkDave - Sir! You are THE MAN!

I experienced unbelievable regret and sadness following a recent software upgrade on my TN-4061F. After the software upgrade, the TV restarted and holy, f***ing sh*t - the picture is whacked-out!!!!

I performed the procedure, as stated, to enter the service mode and correct the Lvds Tx Fmt from JEIDA to VESA. Problem solved!

It is extremely unfortunate the Samsung is not readily forthcoming with this simple fix, or does not have this information listed somewhere in their documentation. However, I also understand that giving just anybody the keys to the tool box, without some knowledge of the tools, also creates its own set of problems.

Thank you! Thank you! Thank you!

Thank you GFunkDave!!!

I mirror the sentiments of krazyhorse. The same exact thing happened to me, and the same correction helped me.

Thank you so much my friend! Thank you for posting the fix. I was sad, now I'm not.

I just happened to be back here for the first time in years - very gratifying to see that I've helped a lot of other people with this.

I still have the TV...though the Source button on the right side of the TV is getting a little wonky...doesn't always respond if you don't press it very firmly. Otherwise, it's still a nice TV.
