I was playing video games on a friends’ Samsung LCD TV. The contrast was too dark, so we adjusted the picture settings. After about every 10 minutes or so, the picture would just go right back to the same settings it had before we changed them. It wouldn’t save the contrast or brightness settings.
This appears to be a common issue where the television is in “Shop Mode“. Shop Mode is a type of mode that is used for televisions that are on display in a retail store. You will need to get it out of Shop Mode and put the TV in Home/Dynamic Mode in order for it to save the picture settings. Try these steps.
- On the television, push the “Volume Up” button once then let go.
- Now from the remote control, press and hold the “Menu” button for about 10 seconds.
- When the screen flashes, you should see an area where it will say “Dynamic mode“. On some models, you may have to press “Tools” and set “Demo” to “Off“.
But that didn’t work for me!
Some models such as the HW-M550 require these steps instead:
With the TV powered off, press and hold “Volume Down” on the TV until the words “SHOP OFF” appear on the screen.
