How to Remove Persistent Icons from Samsung Series 5 LED LCD TV Screen?

HI, my name is [REDACTED NAME]. I am happy to help you with your problem. I will be providing some steps that will resolve this issue. Please give me a few minutes to prepare the answers. Thank you for your patience. --- Ok I will await your response. Thank you. --- Your TV is set to store or shop mode. In this setting, the TV is set to do this when this mode is selected to showcase the features of the TV. There are several different ways to get it out of this mode, depending on the model version and software of the TV. If you can give me the model number located on a sticker at the back of the TV I can give you the steps on disabling the shop mode. Thank you. Will wait for your reply. --- Hi again, To save you some time, try these steps to get your set out of the demo mode: Press the INFO button on your remote to confirm your TV is in Demo mode or Shop mode. If it is, try to disable it by: Press the volume down button on the TV itself and hold it down. When you see the volume bar on the screen, press and hold the MENU button on the TV itself for 5 sec. NOTE: These buttons are on the TV itself, not the remote. You may want to press the INFO button on your remote to confirm your TV is no longer in Shop Mode or Store Demo Mode and should say Dynamic Mode. I hope the information given helps. If the answer to your question was informative and helpful, please show your appreciation for my efforts by clicking the green Accept Answer button right below my first response. Thank you. --- The model number is: LN37D550K1F. The instructions you sent to go to info did not help as we see no info button on the TV. --- The info button should be on the remote not the TV. Did you follow the instructions on holding down the volume button till you see the volume bar on screen then press and hold menu for 5 seconds? The TV screen should display Dynamic mode after that. Let me know what happens. --- Please let me know if you still need help. --- Hitting info did nothing, but it is already in dynamic mode. --- Hitting info is just to know what is the mode of the TV. If after pressing info, the TV says Dynamic mode, it means that it is out of the demo mode. Now turn off the TV and turn it ON again. Do you still see those unwanted symbols on the screen? --- Yes we still see them. --- Please note that we never located info. We found out it was dynamic mode by going through the menu. --- Are you still here? --- Here is a sample of a LN series remote the INFO button is just above the red button. Anyway, if you still see the symbols please follow the steps below. We will not use the remote this time but the buttons on the TV instead. Press the Volume + on the TV till the volume bar shows up on the screen. Immediately press and hold the MENU on the TV for 5-7 seconds till you see Dynamic show up on the screen. If Dynamic or Dynamic Mode is displayed on the screen, your TV has been removed from Shop Mode or Store Demo Mode. Let me know what happens.
