I'm sorry to hear that you're having this issue.
If you're connected with a cable/sat box, try unplugging the unit, waiting about 10 minutes, and plugging it back in. Often times, a simple reset will allow the picture to pass correctly.
Does that help?
The picture on my television went of last week, the sound is fine.If i put it on the picture would come on after 5-10 minutes, but this morning there has been no picture at all.
