Re: e701i-a3 no picture but backlights
Just an fyi, I just did a repair on one of these 70" LCD sets and it was the LEFT side (as viewed from the front of the set) that was defective.
Also of note, there were NO discernible bright horizontal lines or bars across the screen. After replacing the mosfet on the tcon board and disconnecting left side ribbon, set powered on with a picture. Right side bright and left side darker.
Pulled the left side boards/ribbons off LCD panel and set now has a flawless picture.
