Since the release of a firmware update that added Dolby Vision support to Sony OLED TVs back in March, a significant number of users have reported an issue that causes the display to dim.
This is a built-in feature intended to reduce burn-in when the user has left the device inactive displaying a static image for a period of time, but users say it is happening randomly, momentarily and for no apparent reason.
Sony said a firmware update issued since was intended to fix the issue but ongoing bug reports from users have put paid to that. The company has also mentioned that its AF8 model isn’t affected by the fault but a number of owners suggest otherwise.
The company has acknowledged the problem and promised that a fix is on the way via a future firmware update, but provided no timeframe for release.
