Major Dimming Problems With Sony OLED TVs Revealed

One of Europe’s leading TV reviewers John Archer whose reviews often appear in SmartHouse has revealed a series of flaws and firmware problems that are plaguing Sony TVs this time with their top-end OLED models.

According to Archer the latest issue sees pictures on Sony’s A1 and more recent A8F OLED TVs suddenly dimming down dramatically across the whole screen if you watch something that has a static image element in it for more than a minute.

He cites as an example a video game with fixed HUD elements, or sporting events with static onscreen graphics.

This is not the first Sony OLED to have a problem the Companies A1 OLED TV which is on sale in Australia. Online there are several video’s that reveal the problems that Sony are facing.

Ironically the Sony OLED panel is made by LG who don’t appear to have the same problem with several experts pointing to the Sony content engine.

In Europe hundreds of Sony OLED owners reporting that it made the recent World Cup tournament pretty much unwatchable, as well as spoiling the vast majority of video games that they play.

Archer said that the dimming is particularly prone to occur with high dynamic range content but can also happen with standard dynamic range content if an A1 or A8F is set to its high or even medium peak luminance level.

This distracting dimming was not there when the A1 OLED first came out and is widely accepted to have been introduced to Sony OLED TVs in January by firmware update v6.2858 (the update which, ironically, also introduced what turned out to be a problematic new version of Dolby Vision to Sony TVs with X1 Extreme processors)

Recently Sony has started rolling out a new firmware update that was expected to fix the dimming problem – but hasn’t.

Early reports suggest that the update slightly improves the issue by not dimming the picture as severely but doesn’t go nearly as far as Sony OLED TV owners want it to.

Sony Australia has not commented for this story.
