So below is a video clip of our 75" QLED TV that we've had for a couple of years approx. It's a glitch that occurs every 5 seconds on our QE75Q9FNA. It just spontaneously started happening as we were watching TV this morning.
Doesn't matter what channel you're watching, or if you're viewing photos, other HDMI port. Tried plugging the whole thing out and back in again. Tried updating the software (but already on latest version). Nothing works. It's kind of unwatchable in this state.
Any clues what to do?
The video in the post doesn't appear to be working, so I've uploaded it to YouTube here:
