Vertical lines on screen - model UN65MU6500FXZA samsung TV

I had to put different TV on the device choice as my TV model was not listed on the list of TVs. But i do have the vertical line issue and this tv model does not have the tcon board. i am not sure if changing the main board will solve my issue of vertical lines? any suggestions will be helpful
