Comment by Guest, posted on Oct 25, 2008My Aquos has the same problem. I'm not sure how I discovered this, but when I lean the TV forward and hit the power button it will turn on every time. If the screen blacks out and I don't lean it forward when I hit the power button, the screen will just remain blank. It is very weird, but at least repeatable.

- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

SOURCE: Sharp LC 46D85U TV with NO SOUND (but perfect picture)

Sound like the TV has a defective audio board. Opening up the TV would most likely void the warranty.
It's best to take the TV back and exchange it for a new one. Personally, I wouldn't want to be stuck with a defective TV ( that just came out of the box ) that they are going to repair for you.

Broken lc-42sb48ut


I would look to see if this unit has a back light and if so it may be your problem--either the actual back light or the voltage source that powers it.

Not likely to be a do it yourself repair.
