Problems can often occur with even relatively new Samsung LED Television.
Some customers report their screen going black shortly after turning on the television, and flickering picture even though the TV’s speakers continue to produce sound. You can test and rule out a number of things before concluding that your TV has a hardware defect.
First, check the input settings of your LED TV. Often, users will experience a dark screen when first turning on their LED TV if the selected input corresponds with a turned-off or unplugged input, such as a gaming system or DVD player.
