Hi, My name is XXXXX XXXXX will be happy to assist you today.
Ok, I wait for your comment.
Sorry for the delay I thought I already gave you the response.
I was not able to locate your specific model, may be some mistake with model number. If this is a hardware issue i have feeling that those buttons have some sort of electrical contact happening without you touching them. Try to release them with something pointing may be pin but please make sure safety is first. If not than do a factory reset if you have not done so far. Follow your specific model menu or see manual for instructions or here i found some general information from Samsung that might guide you resolving this problem. If none of these work and your monitor is still under warranty call Samsung on number below without any delay. Good Luck

Without even further investigating problem i have feeling that board behind your button which include menu and other settings has some sort of short circuit. Let me look little bit more into your specific model
Tell me one thing . is this monitor placed in area where you more moisture than your rest of house or generally speaking you live in area which got more moisture in the air. Also if the buttons were exposed to any liquid, especially while cleaning the screen. spraying windex or any other liquid?
Tas: The computer is in normal ambient environment, several computers for many years. I have never used solutions to clean the monitor.
Hope this helps. I appreciate your efforts.
Thanks, Russ P.S. I have never had this problem with any monitor before and this is the only Samsung I have.
I think this is the bad Apple :) how old is this monitor ?
I think from understanding the nature of the problem and few initial troubleshooting we did this is most likely hardware issue with the circuit board behind these buttons on your monitor. Display is good as long as you have something on the screen. Just on a side note try to use air blower and blow on those buttons just in case you have anything messing around underneath.
Here is a website where you can buy refurbished components for all sort of monitors.
Here is my final verdict and honest suggestion. With problem like your monitor have and especially if this is out of warranty there is absolutely no point in repairing even if you find the associated part or getting it done through a service technician. The reason i don’t recommend this is due to the cost. A brand new monitor similar to yours will be around $150 and you can buy a perfectly working used one in your area around $50 - $70 rest you can do the math.
You still there Russ? If you have any question or need any help further with this question please ask. If you are satisfied with my help please don't forget to hit ACCEPT so i can get credit for the help and time. Thanks and have a great day.
