98DIKO, If you've switched on your TV and the sound comes through fine, but you do not see any picture, there are three potential issues. 1) A connection issue is the most common problem where there is a bad connection, faulty cables, or improper installation. 2) An issue with the device connected to the TV. There may be a video output setting on the device that you must set properly before it will output to the TV. 3) There is something wrong with the TV, requiring a technician to assess the TV and find a solution. Please give us the opportunity to assist you by contacting Samsung Customer Support via any of the following options: call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
