My LG 50PY2DR-UA made a popping sound then it went dark, no picture, sound ok. So I got the Y sus, Y-top, and Y-bottom boards replaced, now it has pictures but the pictures are not normal (please see attachment). Can anyone help me figure out exactly what the problem could be? Is it a defected Y board or there's some other adjustments that need to be made? Any pointers would be appreciated!
