The LCD screen might be cracked need new one

I read the suggestions regarding replacing four, slightly bulging 1000 microfarad capacitors. This solved the problem. When I removed the capacitors, I checked them with an ohmmeter and they were all showing low resistance (partly shorted). The suggestions in this blog saved me several hundred dollars and I am very grateful. I would not recommend Samsung again as I feel they are using inferior components. The TV is only two years old and I live in a temperate climate in the Pacific Northwest.

Please check the power supply board, if there is any Pup-Up electrolytic capacitors, please replace them.

the issue is with capacitors on the power supply board ,open your TV and look for caps with damage on the top,the caps are 110 volt change them to 120v
and your issue will be gone.
