Re: Sharp LC-40LE550U. Green light, but no picture/audio

@budm Many thanks.

The power supply board is same (1P-0132X01-1010), after I open TV back cover. I also checked TV last night with little light. The TV can play video from USB memory with sound, and very weak images only seen with flashligh.

It seems back light is broken. I would like to check voltage as you suggested. But I am totally not familiar with the TV, only with electronic knowledge from high school. Could you provide any youtube video that I can follow? Thanks a lot.

I mean the TV is not working last week.

mine was dad last week without picture and without sound. Remote can turn on TV and indicator is without any blinking. What is next step that I could check?
