UE50NU7470 - BAD Flickering issue....

[Stevie_C]

Started this morning, seemed to be no rhyme or reason.  TV was on about half hour, was watching a TV show and thought, their camera is broken.  Then realised it was the TV.

This happens on:

Xbox
Regular TV
Apps

It will be like this for a while then clear up, then start again, could be a space of hours, or minutes, have tried everything I can think of....

Unplugged everything.
Had the TV on a new 'circuit' to itself.
Made sure everything close to the TV was off completely (the only things close are the Xbox and gang plug and they've never been an issue before today)

Power saving's all off.

I'm a bit lost here.  I love my TV but obviously will be heartbroken if the board is going after 2 years.  Anyone have any ideas on how to fix this/what the repair might be?

Oh the only thing I haven't done is a complete software reset, not sure that'll do anything but willing to try if folks think it's worth it.

Just gone through support again and they requested another reset then "you need a repair".  It's now been going for 4 hours taking up my entire evening and I'm just about done with it.  So frustrated.

So was going to buy a new TV tomorrow but thought I'd do more searching for the issue and possible fix, what it might cost and came across this:

Amongst a few other vids saying similar things, it was a bit of experimentation but after 4 attempts (and a massive struggle trying to get the case off, it's still not sitting 100% correctly in one corner) I've got a 100% perfect picture no flickering and it had been flickering all day.

Sorted.  I R now a TV repairman.

Yes, it invalidates my warranty that ran out in 2020...

Imagine calling someone out from 50 miles away to do this for me....  Thanks for the support samsung!!! NOT!
