Solved! tv screen black

[tyrone1274]

I have a Sharp Aquos 70" TV model LC-70LE660U. It went out during a storm and power outage and may even possibly got wet a little. Now whenever i turn the set on all i get is the stanby light on and a black screen and the back lights flashes every 1 minute.

So you have a bunch of possible issues since both power issues and wetness are not good for electronics. Try getting a new system board, maybe power board and replace those, see if that helps.
