Greetings and blessings, friends, colleagues, know that I repaired a Sony Bravia TV 10 years ago, please do not remember the model, but I had some scratches in the image, and I saw a video where they told me that they had to cut a flex track of the video card that is attached to the panel of the lcd screen, and so, I did it and the fault disappeared, what I would like to know is if someone could help me to see the video again or a couple, I searched For the worst website I have not seen another video like that, is that now I have a Sony Bravia with stripes and I would like to know what is the flex that I cut that day, the one I have now is the KDL-32EX400
