No picture sound ok,osd ok.

Check whether it is in AV mode. If not, check and replace its tuner.

l think you mean no picture except for the display for color and sound--If menu comes up also that means the OSD is ok.


Video problem in that case and almost certain the main board is the reason.

colure falt

use the aspect or format in the menu

On a different Samsung TV, there is a Picture Reset in the Picture Menu on the OSD. (It's at the bottom of the list.) Similarly the sound reset is in the Sound menu. There is no global reset. (If your Samsung TV's OSD menus are different try under the Support menu.)

I hope this helps.

Sounds like your OSD is locked. Press and hold the "OK" button for 10 seconds or so and it should unlock.

Try a "hard restart", which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics to a certain extent.
You can also visit the manufacturer's website or call their tollfree number for problem solving info.
Hope these suggestions help you out.

More information is required. What do you have hooked up to the TV and how is it connected? Do you have a menu/OSD (on screen display)?

You may have a problem with the video switching IC. Stargazer
