I have a vizio e550i-ao, i have black lines running through the top 50% of my screen horizontally. i took it apart and removed one of the 2 ribbon cables that go to the lcd. when i did that the screen split vertically and the right side had perfect picture with no lines the left side shut off and was just white also didnt have any black lines. that seems to me like a main board issue and not an lcd problem. can replacing the main board fix that?


things i have already done:
power cycled, called manufacturer and did a reset, tried different inputs
(the lines also appear when the menu pops up) left the tv off for 24 hours.
took the back panel and looked for physical damage on the boards, power source and ribbon cables
