Sony bravia model no: kdl-40bx420 set comes on and there is audio and video. The problem is the lower horizontal half of the screen is green with faint vertical lines on the lower right side I open set and sprayed both connectors and the flat L shaped wire from the logic board to the top of the tv. There was no Tcom board some of the same models have at thetop of the tv.The problem is still there.Need tech advice.
