@choui could be an issue with the button bar or with the main board. You do want to give us the complete model number for your TV. Also, start of by unplugging the set and every component you may have plugged in to it. Let it sit for 15-20 min. Then push the start button and hold it for a couple of seconds. After that plug the TV in and see what happens.

Hi, I have the same issue with my Samsung LA40R81B. Can you help on this please!


I have a neon c3770f and matching remote. I press the source button for the HDMI options, (ps4 etc) and the source button doesn' want to work either
