I've been extending the warranty each year, and now there's a 2 year better deal. Also, I'm covered with my MasterCard double the warranty coverage,

Addendum: Samsung will not extended the warranty a second time.

I may give them a ring to see what can be done. Samsung is obviously under no obligation to do anything, and my expectations are extremely low at that. Just disappointed it hasn't lasted as long as my trusty F8000, which has been absolutely flawless (which, in terms of build quality, I think is one of the last great sets Samsung made). 3.5 years with this set is slightly below my estimation that it would last 4 years.

If I get around to contacting them, I'll throw a post up.

Call samsung executive relations. They bought back both a 78hu9000 and 78js9500 after many panel issues over the course of years. both were outside warranty one over a year. Last samsung I ever bought. Took the almost 8000k then and invested in a 77 oled. Never regretted that decision. This was before sony was bigger into oled but would to this day replace with LG OLED again over sony. for cost and feature set. If you have the time and resources go after samsung. They may just one day send you a url to deposit a check in your account and schedule a pickup for your display.

At this rate, I think your tuneup needs a tuneup as it'll be different results an hour later 🙂 bc aging the display shouldn't produce any dramatic results even after 6 months... You seem to get different results every month and no fw updates...?

Time of the season and weather cause setting changes. (Room temperature does not remain constant - colder in the Winter (Sleep with my window open all seasons), and hotter in the Summer, plus in between Spring and Autumn. Some times changes are subtle when weather, more or less, stays consistent. Anyone who thinks their calibration stays constant, are fooling themselves. Ask a Pro if they stay overnight, and re-check their settings next day - they don't, because they know it will change. Also, after a calibration, the new settings have to settle in. Set always looks better the next day. Why I like to keep on top of things. Skin tones looking a little off, re-fine tune the set. Why it's great to be a DIYer - all it takes is a little bit of your time, and costs nothing since upfront costs are already covered.

Jury is still out after all these years.
Personally, I go along with those that say to calibrate the way you watch. Calibrating without LD, then corrupts the calibration when it's turned On. (Side note: HDR calibration is done with Smart LED on High !)

What about those prices ? Glad I purchased after the prices came down substantially !

Hey guys/gals... so I've "gotten rid of" my beloved UN65KS9800 and have since replaced it with an LG OLED C9, which I've had for two days and am very happy with.

For the curious as to why....

I got some screen burn-in on the KS9800, which is warranted for "life". Samsung authorized service verified, and Samsung agreed to replace my unit. I chose the refund option. In case you'r interested, the set depreciates (according to Samsung) at 20% per year. So in my case their only giving me 40% of my purchase price.

I HAVE YET TO RECEIVE MY REIMBURSEMENT/PAYMENT

My set has been picked up.... status of my refund is "approved, submitted to accounting". It's been in that status for a week.... I remain hopeful this has a happy ending, and without attorney involvement.

I think it's going to be interesting what owners of OLEDs have to say after 5 years of use ?
Note: all my systems are protected with APC Battery UPSs, and the 3 main systems with Monster Line Conditioners as well. So far, all my sets have gotten at least 10 years of life, and those who purchased my old units say they're still working fine. (Except one unit that got hit by lightning, and they had no protection in place.)

Can you detail out the differences between the HDR picture quality between the two sets and were you watching on movie mode or something else on the KS? I myself am planning on replacing my excellent KS with a C9 but will have a hard time finding a buyer for it.

"High-end" televisions (which the KS9800 and C9 OLED are), I've come to learn/treat as "disposable". I don't expect more than 5 years. By then, technological advancements as well as 8K will compel one to "upgrade" anyway.

Bottom line is I can tell what all the hullabaloo is when comparing OLED to LCD. The former is "better".

I wouldn't be the best judge of HDR comparison because I don't watch enough of that content.

I can tell you that the C9 bests the KS9800 and its half the price (at full msrp when at its peak).

EDIT: I typically watch in movie mode on the ks9800. That is equivalent to isf dark on the C9, which reviewers claim is "very accurate and the most accurate" right out of the box.

Hello all,
I'm looking for the service manual of the UN65KS9800FXZA. I got no picture on my TV and I'm not sure if it's the panel or the LED board.
It would be nice if anyone could share the service manual so I can trace the problem.
Thanks a lot..

Sorry, no service manual.
Remove back cover, check that all connections and grounding screws are tight.
Check power supply board for bulging and/or leaking capacitors - either repair, or replace.

Refund has posted!

With respect to the post I made 01-03-2020, 07:43 PM, Samsung finally made good on their promise to reimbursement me for the burn-in. Money was direct deposited today. The process was long and arduous, but it's over.

If you don't mind, I'll continue to monitor this thread for a long while. In some sense of the word, you guy's/gal's are like "family"

I was about to post a link since I ordered one myself a few years back for mine. SamsungParts does have all the service manuals as far as I can tell. It was a godsend when I lost one of the screws to mount the base to the TV (since I had to order the right replacement screw)

Not at all.. really not sure what happen. TV was on the wall with a swivel mount.

I read stories that curved screen are prone to internal thermal crack..

I'm not buying curved until another type of flexible screen is invented...

That's as bizarre as the burn-in I experienced.

Speculation.... On this particular model, Samsung uses a "moth eye" screen. If you look closely at the screen it actually looks a bit different than flat panel screens. Perhaps the plastic itself is somehow more porous or prone to issue. Note that Samsungs lower model curved sets do not market the screen as "moth eye". This is all conjecture on my part.

HDMI 4 SDR Only

Swapped out my DVDO IScan Duo (10 Point Grayscale) for my Lumagen Radiance XE-3D (21 Point Grayscale)
Upgraded my Calman to Version 15.10.2.49
Since this doesn't affect the HDR, have only calibrated HDMI 4's SDR settings. (Note: At this stage of the game, HDR values rarely change)
Main reason was to flatten out the 5,15, 25, 35, 45, 55, 65, 75, 85 and 95 settings.
Compared to my old HU9000 + SEK-3500U that had many issues for the in between points, the KS9800 had very little tweaking changes, except for 95%, which had a large spike. 21 Point now ruler flat. (0.2)

This was the resulting settings now calibrated with the new software and signal generator.

Dynamic HDR Settings?

Yes. Well, sort of. When I do A<-->B comparisons with these new settings and a standard HDR calibration, the picture using the new settings subjectively look more impressive than with the standard HDR calibration. The picture isn't drastically altered but it does provide a noticeable improvement to the colors and the contrast. I've seen a similar difference in picture when comparing a calibrated HDR Movie mode with dynamic tonemapping to a calibrated HDR mode without dynamic tonemapping on a QLED set.

So the main difference is setting the Dynamic Contrast to Low. Dyanmic Contrast seems to perform picture adjustments based on what's on the screen. The issue with turning on DC is that it comes with a luminance boost that takes the picture well above the PQ curve which usually blows out bright details and distorts the dark details. Luckily while in Movie mode you can use the Gamma, Contrast, and White balance, specifically RGB Offset, controls to reverse the luminace boost and so that it follows the PQ curve. This leaves you with the proper luminance and the adjustments DC applies to the picture.

Since these new settings use Movie mode for HDR, I had to make new Movie mode settings for SDR. The color settings target the wide color gamut instead of SDR color. It looks similar to my HDR+ mode.

I'll give the HDR settings a try but I have always wondered why there's only one set of White Balance settings for both Auto and Custom colors as one set of WB will make colors look different in different color settings. There should be two sets of WB settings, one for Auto colors and one for Custom colors right?

Also, why make the SDR setting mimic HDR+, why not just use HDR+ and keep SDR looking like accurate SDR?

USB/APPS SDR/HDR settings - Corrected !

Apparently, like HDR settings, a file or App MUST be running to read/install USB/APP settings !
Elsewise, only the HDMI settings will be read, or worse yet, written over ! (Only took how many years to catch on - must be my age!)
