Samsung flat screen tv no picture sound only, I have checked all connections and remote still same problem.

To troubleshoot a Samsung television that cannot connect to a network or particular apps, check to make sure there is a network connection. Use the remote control or buttons on the television to navigate to Menu, Network and then Network Status. If there is no connection, ensure the Internet router is properly connected to the television. If there is a connection and the problem persists, contact your Internet service provider.
If a Samsung television is experiencing distorted picture or sound with an external device, make sure the device is connected to the television correctly. If the connection is fine, perform a TV Self Diagnosis test by navigating to the menu, selecting Support, Self Diagnosis and Sound or Picture Test. It is also worth trying to change the picture size using the P. Size button on the remote.
To troubleshoot problems with lost settings, change the television to Home Mode by selecting Tools on the remote and changing Store Demo to the Off setting. Issues with the signal can be solved by selecting Source on the remote and running the Auto Program function to search for channels.
To access the on-screen manual for a Samsung television, press the Menu/123 key on the remote, and select Support from the menu. From the Support menu, select E-Manual. This opens the user guide on the television screen. From the screen, select the issue that the television is having.
Sometimes, the television simply needs a reset. To allow the TV to rest, turn it off, unplug it for 10 minutes, and then plug it back in, and turn it back on.

Hi there
I would go to menu on the remote , from there to picture go down the list, if you do not find anything there to help you. Go to Support and to the E manual .

It all depends on the connections and cable.
If you are using a HDMI cable and have sound but no picture, then your TV probably needs to be fix.
if you are using a RCA cable or component cable, make sure that you have the correct TV input.
you don't specify what type of TV you have, but if I were you, I'll check the connections first.
