Kdl-55W800C no display fault

Sony model Kdl-55W800C set came to the workshop for repair, its image was not coming,I opened the set and started fault finding, then it was found that its panel is faulty,the gate drive ckl 3 and ckl 2 of this panel.Checked,they were showing shortage between each other,I cut these tracks,then the picture of the panel came,but vertical lines were forming in the picture.I isolated all its gate drives with tape. Done, 8 gate drives are used in this panel along with Vgh_l, Vgh_odd, Vgh_Even, and U107 point is Vgl minus voltage. After isolating all of them and cutting their connection with the panel,my panel started working perfectly.
