No picture on my television.

When turning on my LG Google 55 inch tv I get no clear picture. The screen is dark but I can see the sihoulette of the picture in the background. The sound is good.

I DON'T NEED TO CORRECT MY GRAMMAR OR ANYTHING ELSE. IF YOU CAN'T UNDERSTAND WHAT I AM TRYING TO TELL YOU THEN YOU ARE THE ONE WITH THE PROBLEM. I DON'T THINK YOU KNOW WHAT YOU ARE DOING. DISREGARD MY REQUEST. THE PROBLEM HAS BEEN TAKEN CARE OF BY A REPUTABLE TECHNICIAN. HAVE A BLESSED DAY!!!!!!
