kdl-50w755c keeps auto dimming

[matrigw69]

Hi, my kdl-50w755c android tv keeps auto dimming. trying to watch walking dead and the dark scenes do an obvious light level adjustment. I have turned off the light sensor but nothing. It brightens up again when I hit the volume botton or something. the content is being played out of my sky box through HDMI. does anyone know anything about this problem? I have searched the forums and cant find anything...

Hi there 

I was going to post the exact same thing to request confirmation from others.  I too can confirm your issue.  I am watching Buffy on my Media Player which is connected via HDMI to my AV Reciever and have noticed the screen slightly brightens up when adjusting the volume, and dims again when the volume popup disappears from the screen.

I will add it to the list of bugs and issues.

Cheers

thank you. It's certainly a problem, especially on dark scenes. Cant see much at all and ruins the picture.

Hi,

I found that if you press "Action Menu" on the remote, select "Picture", scroll down to and select "Advanced Settings", then on "Brightness" option, scroll down to "Adv. contrast enhancer" change it to "Off"..... this stops dimming of the vol control and in dark and light TV shows/Film scenes. 

Worth a try!

Thanks for the tip @theshamelessmanc  i find that i prefer it on, except for this particular issue which doesnt happen on my 2013 TV.  

Cant test yet, as i have lost control of my own tv !!

Id like to have it on too, but found it to annoying when watching films and TV when the screen kept dimming, and brightening back up depending on the scene! Until a fix, I suppose it will do.

thank you very much. I really appreciate your help.

Hi, 

Has it worked for you? Not ideal, but hopefully just temporary!

I have seen this issue on long duration very dark scenes in movies from DVD they seem to be reproduced well as a very dark scene but after about a second or two, the brightness will suddenly step up. I have the adv contrast enhance set to low, which reduced the problem and sometime turn It off. The problem is less of an issue with normal broadcast channels. 

My set is a 43W805C.
