Samsung Q9 picture flicker issue...

[usercFF34iPD0q]

I have a 2018 Q9FN 65" TV which has developed an issue over the last 6 weeks. I have uploaded an example of the issue below, which is worst when watching Sky Q, but is impacting different sources (PS4 Pro, PS5, UHD Blu Ray player) with the same symptoms, just to a lesser degree. After the TV has been on for a period of time and I have anything UHD/4K set as the input, the picture flickers and drops out as if the signal is out of range. Switching Sky Q from 2160p down to 1080p eliminates the issue straight away. The One Connect box connects to a Denon X6300H amplifier and has been this way since I got the TV on launch in 2018.

Troubleshooting done so far, but with no luck at resolving it:

• Removed amplifier from the situation and connected sources direct to the One Connect box
• New Sky Q mainbox
• Sky engineer been to check dish and external connections
• Used 4 different HDMI cables
• Moved the One Connect box
• Disconnected everything but a single source and the TV
• Moved electrical devices to make sure it isn't interfence
• Reset the TV to factory settings

Has anyone experienced this before? I have narrowed it down to what I believe is either an issue with the TV or the One Connect box, but a TV that isn't that old and is never moved, it's hugely disappointing for this to happen with the set only months out of warranty. Any advice appreciated.

Cheers.

I recommend letting a service technician have a look. Send your full model code and serial number via private message to get started.
