PN58C8000 Pink Banding - Page 5

post #121 of 137
So, no worries about putting it in the Styrofoam while the back is off? That just sounded dangerous to me, but haven't really looked at it. I looked for stands when I first got it and was quite surprised at how expensive they were. If I can find a cheap ebay knockoff, I would do that, but otherwise, will likely try to sell as is, but through in the wall bracket as I won't be using it with the F8500.

You should have no issues. You might remove the right and left lower screws and then place in the blocks to remove the balance of them. There will be no issues. I stood my C8000 in it's blocks to attach the base and I've got my F8500 blocks here and I'm quite sure it will work well. It won't be there very long for the procedure.

Let them use the F8500 box to transport it since you don't have your C8000 box but I'd be sure to get it returned. When uncrating your F8500 just unlatch the four lower latches on the carton. There's no need to tear it open.

Buy or borrow a DMM.

I'm quite surprised they didn't have the TSB applied but perhaps the visit by the third party technician wasn't aware of OR didn't feel it a viable fix. The repair facility has to stand behind their repair for a reasonable time and perhaps they didn't think it reasonable. Not every visit could go the same.

I have been reading this thread for about a week now.
I was gifted a Samsung PN58C680 that had the pink banding issue.....after some reading and finding the Samsung service bulletin... I broke out the trusty Multi Meter and adjusted the VS voltage from the current 200VDC up to the recommended 213VDC....Panel is fixed.
Hardest part of the whole process was removing the 20 screws and reinstalling them.
I do recommend you have a couple extra hands to hold the panel upright while you adjust the voltage...and check the picture.

Just my $.02

Made the change tonight. Went right to 213v. I leaned the TV against the couch. I didn't really use a test screen, just went off voltage and I would say I am 99% satisfied. I still see the slightest touch of pink in upper right corner in Chrome on my HTPC, but it doesn't show at all on any other input. Very grateful for this advise. I didn't have to shell out much of anything to upgrade my TV, but I can imagine if I would have because of this issue and only found the solution afterwards, I would be quite angry. Instead, I have a much better TV to sell and a possible solution if I run into the same issue on the F8500. Thanks all!

Question, what do you think I should be listing this TV for sale at?

To Anyone that's made the voltage adjustment.Does the voltage adjustment "completely " get rid of all pink/magenta on full white screens?

Look on craigslist or another site and see what they sell for.People charge a lot for used hdtvs.

i'd say 99% gone - you can only see it sometimes when you really look for it

Ok thanks Hawnr6.Reason I asked was because the abl makes the lighter/whiter screens warmer/redder.
post #131 of 137
It was 95% gone. I didn't spend a lot of time fine-tuning it and on all input devices but my HTPC it was gone, so I wasn't too worried. Because the TV is so old, not a lot up for sale and even less with pricing. Can't really go off used Amazon prices as realistic, so I am just looking for some general opinions - what would owners list theirs for?
post #132 of 137
Answer my own question.In service menu I lowered all white balance too 128 or lower and it has reduced most of the "pink/red color film" on full white screens.I'm still seeing discoloring in the brightest white areas like clouds,waterfalls though.I lowered white gains about 25 each which is quite a lot.bias just slightly reduced.....NOTE I have too completely readjust the whole white balance all over though.I have to do more tweaking ,but now it's a bit softer looking on some stuff and much cleaner on other stuff.****I use cool color tone on tv which has the exact same color/white balance as the service mode****.Be aware you can fry your tv by going into service mode, and write down the settings before changing anything.

Edit I've still got somewhat minor pink bands going across full white screens which I only notice on white screen commercials,and a couple of very minor purple blotches/dirty screen panning on hockey.Its still seems like a big improvement the way I did it,however I'm not sure if I could of just lowered red gain to zero in regular menu.

Just adjusted my 58c8000. Vs was at 210 and sure enough 213 did the trick. Took the yrr clockwise from 3 o clock to 4:30 and have noticeably better blacks also. Just FYI, there are two adjustment pots right next to eachother in the yrr area. Its the one on the right. Will definently hold off on the 8500 purchase as my plasma is performing better than ever. Also keep in mind the back panel has two types of screws. They are the same size but the outer screws are threaded differently than the inland screws. Please keep these separated.

Oh its definently gone. What's left behind is the usual dithering that may be mistaken for banding.

Just completed the voltage change on our PN58C6500. Found the voltage was set at just a touch over 209 volts. We had a tremendous amount of pink banding at the top and abouut 1/2 of the center. Our unit was purchased in 9/2010. With a volt meter I moved the VS pot upto 213 and OMG the tv picture is better than new. Now only if the voltage fix holds for another 3 years or so!

Thanks to all of the folks who have contributed to this resolution!

Is the firmware update described in the service bulletin required in order to safely adjust the voltage?

Ready to do this thang tonight....

Did the update. No pink banding anymore. Set the voltage to 212.8, a bit above where it stopped showing the band but a bit under 213.... Also, my firmware was up to date before performing the adjustment.

2 questions:

- Is this something we can expect to encounter again / have to make another adjustment in the future?
- Can someone please provide the link to the CNET recommended settings (or are there other more qualified recommended settings available)?

Thanks!
