Sony KD48A9 OLED with software update.

Hi Guys,

Having a problem with the picture brightness. Switching the TV on to watch a live program such as Euro 2020, This Morning, The One show etc, I am noticing that after a short while the screen goes dim. Flicking to another channel and then returning brightens the picture for a while before it dims again.

I have checked eco, and ambient light settings and they are set to off. I cannot find anything else that could cause this. Have I got a rogue ambient light setting, or is auto brightness control playing tricks? 

Any help would be appreciated.

Thank you

Graham

Hello graham13,

Try to reset the picture settings to default by pressing Home - settings - display & sound - picture - reset. Also make sure to get your TV up to date from here: https://bit.ly/3oaMN8k

Hope that works!

I have the same tv. I turned off auto brightness after watching a YT vid by a TV engineer, who, along with some other great advice on picture settings, claimed it was an annoying gimmick.
