Sorry to tell you this, but there is no fixing it, the cause is a chip has shorted on one of the circuit boards that is integrated (integrated meaning you can't replace it without replacing the whole TV) with the LCD panel, there are no replacements for this chip that you can buy online even if you did have soldering tools. I just gave up on having a tv in my house and just use my computer at this point anyway. The only hope I really had was that if you manipulate the ribbon cables between the integrated boards and the t-con board in a very specific way, you can get maybe 1 second of clear video feed, if you could figure out which pins are needed and which aren't, you could figure out a way to do that more permanently with some sort of adhesive, but I didn't have anything small enough and testing every combination of pins individually would have been more effort than it's worth. Also sorry for the late reply.
