Sony bravia kd-55xg8196 backlight bleed

I have a huge problem with the tv. Mostly in dark internet movies and dark scenes, the backlight of the panel brightens and darkens at a very disturbing rate making it impossible to watch the movie. Things became worse with the last firmware update.

Hi picard01,

Please try to lower the setting of the contrast enhancer.

Plus please activate the light sensor for a better viewing experience in the evening.

Cheers

Peter

if it only was so simple my friend...

I think it must be fixed via a firmware update or....worst case scenario... service the darn thing.

Have you tried clearing the cached data to improve the overall performance (Settings - Storage & Reset - Internal Shared Storage - Cached data)?

There are also different picture modes you can enable/switch between, does the issue happen on all of them?

Yep, no luck. I will later post a video showing the problem.

The right suggestion was already given with the first answer from Peter. You bought an edge led tv with an IPS panel that cannot have by definition any local dimming but just a frame dimming. The effect is what you see: if you have a spot highly illuminated in a dark scene all the frame will get more backlight (i.e. when you have the subtitles). You can disable the side-effect by disabling the advance contrast enhancer but you get a greyish overall look of the blacks.

The result that you want to have is more possible buying a VA FALD panel (like last year XG95 or this year XH90/XH95 models) but you have to pay more. The optimal solution is an OLED TV.

Why is it that this is not happening with same technology other brand tv's? This happens mostly on internet and usb movies not on cable tv channels. It looks like a defect of the Sony Bravia rather than just a glitch of the LED technology. Nobody in the right mind would buy such a TV, with such a defect. In some cases backlight flashes rapidly making it impossible to watch.

It happens on any tv with the same technology and frame dimming enabled

By frame dimming you mean contrast enhancer?
