Flickering Tv every second

Joe Rabago  it’s a VIZIO which makes it complicated since there are no schematics etc. that are readily available. In general anytime you have pink/purple screen, this can be cause by a failed T-con board as well as failed backlight arrays. Your TV may have a main board that also has the T-con board integrated. We will have to see what you got in the back of your TV. Post some good pictures of your boards and the interconnect cables with your QUESTION. Of course you will have to remove the back cover for that. 在已经存在的问题里加入图片
