I Have SAMSUNG UA40H5100AR TV, my problem is that there is no sound from tv speakers but I could use external amplifier and speakers that works fine, initially sound will come back after switching on off input power now it is completely dependent on external amplifier and speakers.
Hello saqib, Use menu icon on remote and access the main menu Find setting Sound menu Reset All: Reset all sound settings to the factory defaults After completing reset - turn off the Tv and Turn on it back Hope internal speakers start to working inorder
