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.
Thanks to commenter, Zehra McAnallen, i was able to finally fix my picture settings, thank you.

Thank you very much. It worked for me in such a wonderful way, I have just press the button (have only one button) and at the same time press the menu key in remote, Viola!!! THE SHOP MODE IS OFF. I used my tv as a secondary monitor for my web development pupose and not having a glaring screen is like a bliss.

Once I changed source to tv, I was then able to access plug and play. Settings have stayed the same!! Thanks imran!

Thanks for the advice! It worked for me by pressing the volume up button on the TV, then holding down the menu button on the TV. Until he said it was normal.

Mr. Imran. You are the best, Thank you! Now I can finally enjoy my TV.

That worked amazingly I’ve had this issue for a year tried everything this was the only thing that worked I’m so grateful would never have thought to change the source to TV
If anyone is still having trouble; I managed to find a way to fix my problem from the e-Manual/help section in the TV Menu.
My issue was the Plug & Play button was greyed out so I could not click it. My TV was in Store/Demo Mode and I could not change it to Home Mode.
What I did:
1. I changed the source to TV.
2. Once I went on TV, it finally let me click Plug & Play in the Menu.
3. I went through the Plug & Play settings and finally changed the mode to Home Mode.
Hope this helps!
The internet kept telling me to turn off eco-mode to solve the automatic darkening problem. But my 2008 Samsung doesn’t have eco-mode. I found a fix for the automatic darkening under “setup” – “plug & play”. There, among other options, I was able to switch from “shop” to “home”. After that, all customizations to brightness remained permanently.

I was having the issue with the screen reverting to a very washed out color palette every time I would turn it on. I would have to go into the settings and reset it to the picture mode I wanted, also the stupid Samsung garbage bar would show up any time I did anything and I would have to manually clear it. I already changed the television from Retail to Home mode and turned off the Samsung bar. What worked was holding the “Down” volume button while the television was off for about 2 minutes. The next time I turned it on those two changes were adopted and it has worked since.
I have this same problem my tv goes back to its setting and it sticks .. i have to unplug it and then plug back up .. sometimes it stay and sometimes it doesnt … this is getting really old … nice tv … but it doesnt last very long ..
I have a Samsung Q90 and this works for me.. I did a factory reset on the TV then went to General / Eco Solution and noticed that Ambient Light Detection was set to on which must be the default mode. I turned it off and the dimming issue came back about 10 minutes later.. I checked and Ambient Light Detection was on again! This time, I tuned it off and stayed on that menu screen until the tv went back to the main menu by itself. That worked.

I’ve noticed something interesting…when I turn on the TV with the remote, it starts off with the setting I previously made. Then I see it signs into my Samsung account and then the setting change. Is it possible the TV is pulling setting from my account and applying them to the picture? I can’t get the EcoMode to stay off once the TV is turned off and back on. This TV is crazy!!!

My brand new 2020 model Samsung Q70 75inch TV keeps reverting back to ‘standard’ picture mode. No matter how many times I change it to ‘movie’…
The shop/home mode is an option directly in the settings so that’s changed to home, so it’s not that?
I had the same issue and was able to resolve it by turning off eco mode, specifically the eco sensor, which was resetting brightness and contrast based on the light in the room.

I’ve tried all of the above on my 75” 4K Samsung TV and nothing works. In Picture mode always goes back to Contrast at 100. I’ve owned the tv for maybe 5 years, this is the second time this has happened.
IT WORKEDD WITH MY PS4 thank youu

This TV came to us used from a family member. It has worked fine for for the past 3 or 4 months but suddenly the picture is too large for the screen. I have tried to reset it via the standard fixes using the remote and on-screen instructions. Nothing seems to work, including the suggestion above.
This didn’t work for me, but the instructions on this webpage did: https://www.samsung.com/in/support/tv-audio-video/why-samsung-tv-settings-changes-automatically/
This is a joke. I have a $2500 tv that changes backlight and contrast to max every few minutes and a $150 Vizio that seems to work just fine. Yay Samsung
This didn’t help, demo mode is set to off. Are there any other solutions
none of the above worked , it keep changing screen size and brightness after 15 minutes , all the time.
every thing that can be normal is set to this and no auto anything
Thanks for sharing this information with us.”Shop Mode is a type of mode that is used for televisions that are on display in a retail store.” thanks for explaining this I don’t know about this mode.
