QLED Q7F displays a white picture for a split second!! Randomly

[timstack]

I switched over to HDR+ using Movie mode and haven't seen any white flash for 3 days now.

changing the settings or even replacing one connect and cables very often will alleviate the flashes for a while, then they will eventually return.

Hello, I’m within my return period of a Q6F, and will be swapping it out. I have the same flashing issues. There shouldn’t be this many issues with a small box.

its not the one connect box causing these issues. Well atleast for most of us. I swapped out mine, and I still got flashes. Doesn't hurt to try tho

I just got my Q7F yesterday and the one connect box isn't working(allegedly). now I'm waiting on a new box which takes 5 to 10 business days. yay Samsung. I'm thinking I should just return it considering I bought it for my Xbox one x... yay for a 1600 dollar door stop!

Okay so here is what i tried so far,   I have purchased premium surge protector cost 50 bucks for 4 ports. Didnt work,  tried plugging in the wall, problem still persisted.  Purhased a brandnew ethernet 6a cable for both my xbox and one connect box, problem still continues.    I am about to try the last option.  I turned off hdr in the general settings and will report back if it happens.

i wish samsubg could address this.   Obviously many people are experiencing this!

I also want to say its not always a white flash, sometimes it looks like its a green flash, it occurs sooo fast its reallt hard to tell. Audio is not interrupted

It only happens with external devices too. If I watch Netflix through the smart hub, it’s perfect. This tv is the biggest piece of garbage. First 3 to 5 second blackouts with Ps4, and flashes. Now flashes with Xbox. My flashes aren’t the entire screen. Usually it’s just a subtle white flicker on one part of the screen, or a brighter white flash the size of a fist. I would like a full refund for this tv. I just don’t have the time nor patience to be battling with Samsung. They are never any help and are always clueless to what’s going on.

Okay so i am 95% sure that it has something to do with HDR.  I turned off the HDMI UHD Color settings and so far i havent seen a single flash.        Samsung please address this,  sounds like a software issue 

[userA340TQVDsq]

It’s definitely a software issue with UHD color mode. With the PS4 Pro, I was getting the 3 to 5 second blackouts. With this setting off, it stopped. With Xbox, I don’t get blackouts but the one quick white flash and and there. It stops when UHD is turned off. Keep in mind, I had my one connect box replaced, 3 different hdmi cables, as well as main board swapped. It’s a Samsung software issue. I’m happy I’m not getting the blackouts anymore, but the flashes are definitely related to the blackouts. All stems from the same issue
