Q9FN random reboot

Statherian — Tue, 28 May 2019 20:32:44 GMT

Hi, new to the forum.

My 4 month old 2018 Q9FN has started doing quick random reboots the last few days. It suddenly qoes black, displays the Samsung logo and then is back to the same input - takes about 3-4 seconds. So far it has only done so while using my Xbox One X (which is annoying), but at random times - 1 time each evening. I've reattached all HDMI cables and the One Connect cable, and setup all inputs from scratch. I have not done a full reset yet, although I guess that's the next step. I'm on the latest firmware.

Anyone experienced the same? Is this the fist sign of a faulty One connect box?

Exact same issue here. Same TV. Also primarily, if not exclusively, when playing xbox one x. It seems to have started since the last TV firmware update. I wonder if maybe its the console and not the TV?

Interesting... It started after the last firmware update for me too. Since I originally posted this, I've done a full reset of the One Connect box, and I also turned off the variable refresh rate/Freesync option - figured perhaps that might be the culprit, since it only happened with the Xbox One X so far. I haven't used the Xbox extensively after the reset, but so far I haven't had any reboots, so fingers crossed...

Hi All

I have 55Q6FN and Xbox One X and I have exactly the same issue (Reboot, Samsung logo,remote control sensor led blinking and "samsung account is connected".

I'm checking with Freesync DISABLED and and it seems to be no problem so I think the problem is freesynch.

But this is very big issue, because with this panel some games (example Fifa 19) suck without freesync, trails on screen everywhere...

I have 12.51 firmware, I have not updated to the latest version 1260.8 because I read that it really sucks.

Has anyone tried the version 1260.8?

@Statherian

Is not One Connect cable issue, Q6FN don't have the One Connect cable, all is direct at tv.

Samsung support where are you?!?!

This is a big problem, you have to solve !! Affect several models, not one!

I was running into the same problem on my Q9FN. It would only do it during 4k content, like playing Xbox One X or streaming 4k content. I could run my TV all day with regular content and it wouldn't do it. However after 2 to 3 hours of 4k content it would reboot. I also noticed that my One Connect box would get really hot. I hypothesized that the box would get so hot that the system would shutdown to protects itself. There's no active cooling in the one connect box and the heat could not expel fast enough and would just build up till it caused the system to restart to cool itself off. My solution was to buy an external fan to put on top the the One Connect box pushing air down on the box. While it doesn't dirctly cool the CPU, the box will now disapate the heat faster then it can build up. After I did this I have not experienced any reboots even with marathon Xbox one X gameplay sessions and binge watching 4k content. The one connect box is only slightly warm now on the low fan setting. There is no audible noise from the fan on the low fan setting. You could run the fan at a higher fan speed if you wanted to keep the box cooler but low works perfect from my experience. I got the fan on Amazon, it has 3 fan speeds and plugs directly into the USB of the One Connnect. Here is the link to the fan. Well built and has rubber feet so stays in place.

It's only $11 so it wouldn't hurt to give his a try. It worked for me.

I'm sure Samsung is aware of this issue, but for cost measures have decided not to include an internal fan to help with cooling. If you noticed with high end 4k/ or ultrawide HDR PC monitors they have internal fans to help with the cooling.

Update on my solution. My TV did randomly reboot again this morning while playing Xbox. It was about 3 hours into a play session. Although the reboot was much faster. I would say I was back up in less then 5 seconds after it shutdown. It was the first time it did it in two weeks. Where as previously every night I would play Xbox or watch 4k content I would get a reboot. Plus the reboot would take much longer. Around 20 seconds or so. So I would say the fan definitely helps, but there is obviously some sort of design flaw

My Q9FN had a hard lock up the other day. Completely shut down and wouldn't reboot up. Called Samsung tech support, of course no help. My TV is 1 month out of warranty so they wouldn't bend on the issue at all. I was looking at buying a new TV rather then pay for a repair. Oddly enough, I unplugged everything left it for a few hours and the TV fired back up perfectly. It hasn't had a reboot since then and I've put some long gaming sessions in with my 1X with Apex Legends. I also just recently built a gaming PC. I run it in 1440p/120hz, so long play sessions and no reboots. I will be very wary of buying another Samsung set in the future though. Not ruling it out, but if I pay $3800 for a TV at launch, I shouldn't have these problems and Samsung should bend over backwards to make things right. I will be seriously looking at LG for the next set. This is coming from a person who spend $2k on a Samsung 65" set in 2016 and then in 2018 spent another $3800 on their flagship Q9FN. Hopefully this set will last till next year when the new model sets come out. Pretty sad when you spend that much on a set and have to hope it lasts 2 years.

I have the same problem . My Tv restart randomly while playing xbox and Shows the samsung Logo... I have the Q6fn 55" 2018 Qled Tv and Xbox One X. I hope Samsung can fix this Very soon.

Re: Q9FN random reboot

Gg81 — Fri, 02 Aug 2019 16:33:34 GMT

I'm afraid this is a hardware issue! When I play in 120hz mode, the one connect box gets very hot

Re: Q9FN random reboot

Gg81 — Fri, 02 Aug 2019 16:37:52 GMT

Why don't we get any answers? I bought this TV for 120hz gaming! It is thus useless for this purpose!

because samsung is pissing off the problem. NOT BUY SAMSUNG SMART TV. Support not exist..

Q6FN here, also getting random reboots while playing on PC with freesync enabled (ultimate engine). Started around 9-12 May and it's been happening everyday for the last few weeks, this is unacceptable. I will try with basic for a few days to see if basic solves this, but I am extremely disappointed, especially since FreeSync was the main reason I bought the TV.

Later edit: 2 days later, basic seems to cause random reboots as well. Going to try without any freesync for a few days.

It's clearly a firmware update that has caused this, since I've been using it to play PC games since last november and it only started happening in may.

Samsung, we need you to do a firmware update to fix this. And we would appreciate a response from a rep saying this is looked into instead of radio silence.

It turned freesync off on my Qled Tv and played some games on my Xbox One X. I had no Tv Reboots so far with Freesync off. I Think it must have something to do with Freesync. Samsung please fix this error.
