LG Fixes OLED TV Flashing And Blocking Problems [Updated] - Update 7/1/2019 - LG confirms firmware fix is coming, though it may take some time. At least it has now been acknowledged. OLED Blocking And Flashing Problems: LG Responds *Originally posted in owner's thread but thought it be better here to discuss scenes with flashing white macro-blocking. Input from users without the issue is also welcomed as this may help determine if a software bug or rarer hardware fault. --- I got a feeling more people may be interested in testing this scene. Can anyone with Amazon Prime Video please try to play on their LG OLED C8 - Vikings Season 5 Part 2 - Episode 12 and play from 35m27s to 36m33s (1080p HD Only). It is a brief sex scene but that's not the kind of flashing you'll be seeing. Please tell me if it's OK for you, or if it's not. I don't just want to know if it's a problem - it's also important to know if others see the scene play fine without issues too. What I see - in the dark hallway there is constant white flashing blocks that get severe. Then when he's nosing through the door, the box or whatever it is by the door appears distorted and mis-coloured. Almost like cartoon or game graphics in a real-world scene, it looks very odd. There is also continued flashing going on when the camera switch to view the couple in the room. For reference - I tested also on a 4K HDR LCD TV - the Panasonic DX750B, and the same scene did not have the issues that are showing on the LG OLED C8.
