Sharp acquos LC46d62u has a snowy picture

[Jennrbll]

My tv has a snowy picture, more like a light blue lines. Every channel I switch the lines do not clear up. Can this be troubleshooted? I had turn TV on and off. I also unplugged and plugged it. I used dust off to clean it. Any suggestion would be appreciated. Ty

does it look like this? They fixed it by either bending or replacing mainboard.
