Re: Black screen periodically

JUMP TO SOLUTION

I purchased two 40" 4K TVs (model UN40KU6290FXZA) from Best Buy around Black Friday 2016. I use them as dual monitors on my computer. I noticed immediately after buying them that one of them would go black periodically for 1-2 seconds and then come back on. It didn't happen often so I didn't worry too much about it (initially it would go black once every 8-24 hrs). Lately, it has gotten worse to where it will go black at least 2-3 times/hr. I originally thought the problem was with the video card, but after doing some troubleshooting, I've determined that it is the TV. I should note that the other TV has worked perfectly with no problems. Please tell me what I need to do to get this fixed.

If the TV screen goes black repeatedly and you have updated the software, tried other connection cables, have tried to reset the TV, and it's still happening; service would be recommended.

I didn't notice this issue when  first got the tv home, but when I started having the issue a few days later, I did a Google search for the symptoms and found this thread.

I have already returned my problematic TV so that I wouldn't miss the store's return policy deadline.

Maybe if Samsung fixes this, I'll consider getting another Samsung tv in the future or else I'll wait for another brand to make a smaller 4K set.

I really wanted a 32-36" 4K tv that could do double-duty as a PC monitor and found 40" still a bit awkwadly large, so I didn't hesitate to return it once the problems started cropping up.

I'm having the same issue. No video for a second but still get sounds. Happens on every HDMI input with all of my devices. Tried all kinds of hdmi cables. Can't believe there's no solution. Certainly my last Samsung TV.

I've changed hdmi ports on my audio receiver. We will see what happens. Also set hdmi control to ON so receiver comes on with TV power. Still doesn't happen when watching Smarthub or PS4 in different hdmi input (that's why I thought to switch cable to another, since there are 4 on the audio receiver). Still not sure how this is marked solved? The only thing different any of us did was switch to a new Samsung TV and this problem started.

Hello,  

I bought a Samsung 4k UN65KU630D at Sam's Club online.  I set it up on March 10, just hooked it on directv h24 receiver.  No dvr, no other devices connected, didn't even connect to wifi.  Day 2 of the tv, between 7 and 9pm while watching an hbo movie Constantine, tv goes black for a second, then comes  back.  After 20 to 30 mins, happened again. It goes black 4 times in less than an  hour.  We switched channel to another movie, same thing.  I called Samsung tech was advised to reset the tv.  Didn't reset yet. Been reading almost all the post here, the black screen issue has been going on over a year and it seems reset did not resolve other people tv issue, my tv's  mfg date is Jan 2017.  Waiting for Sam's Club store in my area to open and arrange a return and refund if they will accept online purchase return.

Update:  My Sam's club store will accept a return, but it will not be an even product return and exchange.  I have to pay for the price difference.

Hello Fellow Samsung Owners,

I decided not to return the tv yet.  I have two more months on store return policy.  I follow tech's advise on resetting to factory default.  So far since March 11, did not have any issues with blinks except when there is a commercial pause, which I believe is normal.  I also bought a $99.00 protection plan to extend warranty for 3 more years.  Today March 27, I noticed blinking issues again, tried changing channels, same thing.  I unplug and plug the tv power cord for 1 minute, no blink for the last 40 minutes.  I turned it off as there is thunderstorms right now.  Will monitor later.  I love this tv's picture clarity.  Disappointed with Samsung not able to solve this issue that has been going on for over a year.  As mentioned on 1st post, this was manufactured January 2017, they should not let this out of their factory with unresolved issue.

I agree 100%. What is going on with Samsung?? The customer service refuse to even acknowledge this is a growing problem or accept responsibility. They just deliver a template speech to pay even more $ to their qualified samsung service technician because surprise this manufacturing problem occurs as soon as your warranty runs out!

Has the bribery, embezzlement and corruption scandal that resulted in the impeachment of South Korea's President Park Geun-hye and subsequent arrest of Samsung's acting Chief Lee Jae-yong really resulted in a complete break down of quality control and production for this prestigious company? If I wanted subpar product quality and non-existent customer service I would've purchased a cheap no-name manufactured product from China.

My tv goes black for 2 seconds one time every night for 3 consecutive nights, about almost the same time, 7:59pm on Cards and Cubs game, 7:04pm on Joe Buck show and tonight on hbo movie at 7:46pm.  I am baffled with this Samsung tv.
