I have a green led light on but no picture and no sound, any solution?

Adrienne Harrison we will need to know the exact model for your TV. After that remove the back of your TV. Check the power board for power at the main fuse. Then check the voltages from the power board to the main board. Take some good pictures of your boards and post those with your question. That way we can see what you see. 在已经存在的问题里加入图片

Right now this could be any board that may have failed.

这个答案有帮助吗？
