I never noticed it until I was up close looking at the panel for any unusual screen issues. It's not noticable at all until you're looking for it. Just curious if anybody else has the same spots in the corners.

I haven't looked/noticed any on my set and I have never heard about anyone else having this phenomen so I would not call it normal.

Hey guys. Not sure if this is the best place to post my question, or if there's a specific thread for troubleshooting, but I'll pay it anyway and you can let me know 😉. I have recently acquired the 60" version of this tv for free, and it is non functional. I'm not very good with electronic circuit boards, but there are no obvious defects (blown caps, burn marks, etc). I have a standby light, and when I turn the tv on, the power light with blink slowly and continuously, and the screen will flicker for a split second, then go blank for a few seconds (10ish), and then it will display HDMI 1 in one corner, and a symbol -:- in the other. At this point, the tv will become unresponsive. Pressing any button on the smart remote, or the spare standard remote I have has no effect. After about 20 or 30 seconds, the tv will power cycle in its own (you can hear a click) , starting the whole process over again. While it's on, the green light on the main board flashes as well. Any suggestions as to what to try/check next?

Thanks in advance.

Does anyone know a service man that could get a hold of those logic board files?
Surely it would bother noone as this tv is not sold anymore

Would be very nice

Nice. Is the F8500 a lot less reliable than the Panasonics? If so is there a fix?

Usually DIY fixable if you can solder.

What is your opinion on leaving the 64F8500 on standby or cutting the power completely while not in use?
Ever since I did the capacitor soldering, my wife insists on pulling the plug after setting it to standby but
I wonder if that could have shortened the life of the power supply board (which died for me two weeks ago)?

I don't know for sure if pulling the plug can shorten the life of anything; I am a bit suspicious that it can, because electronic components don't really like being hard power cycled. But don't take that as truth, because I a not that qualified.


What I am pretty sure of, is that you do NOT need to unplug the TV, ever. My understanding (from this forum) is that the root of the capacitor problem is heat. The F8500 runs really hot, and Samsung used ceramic caps that were not rated for the level of heat that develops inside the unit.


Idling in standby is not hot.

Well, since these sets don't have a hard power on/off button, I suspect they are only designed for going to/from standby mode and might not tolerate a hard power cycle each day for 7-8 years.

Hey I have firmware 1112
Should I leave it alone. Only connected to net day of setup , but I know black levels decreased, after even the earliest FW updates. Anyone familiar with FW numbers let me know if I'm in a good place, or should I update?

BTW I have no issues with buzzing or panel noise. And I mean none. No lighting issues either.

Probably not but be sure to blame it on her.

I'll chime in here. I am currently running on 8500 hours on a 51" F8500 plasma that I bought brand new in 2015 for $1100. Mostly watch hockey, football, and Netflix. Zero issues except for the minor buzzing but you can only hear it up close. The picture is still phenomenal to this day and I have no reason to switch until it dies. My brother is a tech snob and he recently had to buy a new OLED because his old LG plasma died. Let's just say he offered to buy my F8500 several times since then and every time some of my friends or family come over to watch the games they are usually saying, "Wow, the picture on this TV looks great." I just chuckle and smirk. I hope it lasts forever.

Is there an alternate third-party stand for these like there is for the Kuros? My table is narrow enough that this TV would hang off the sides if its entire width is a stand.

Not sure how that works. Is there a VESA bracket on the TV for a universal VESA stand?

Consult the manual. Most TVs are VESA compliant (have VESA holes) It's the same as mounting the TV to the wall, except it comes with a stand as well.

Samsung F8500

Stopping into the local electronics store today to finally get a look at the 8K TV'S. I was somewhat thrilled at a few although I am still happy with my plasma. My question is can I get a even better quality picture with a Evolution kit? Samsung is offering a SEK-4500. My set is a 2014 model. From reading I see that the SEK-3500 is more of a upgrade, although discontinued. What would be my best option, look on Ebay for a 3500, go for the 4500, or will I not see a true picture quality increase with either?

If you want a better picture quality, nr1 you should invest for a calibration.. Especially Plasma tvs change alot over time..

That said: The new 2018 (SEK-4500) Evolution Kit for a 2013 tv is still a very interesting option.. Picture quality most likely will not improve, but you get for sure newest apps.. I think it is great that Samsung pulled this of after many complaints..

these things are cheap now, albeit used. i originally picked up 60" for my main viewer, but recently picked up a couple of mint 51" versions for $150 and 180 respectively - one for the bedroom and one for a friend who i refused to allow the purchase of a newer (o)led tv.

if you like this model, keep your eyes peeled.
