Two red line on the screen

@alitawash those do like a TAB error. That is where the bond between the thin ribbon cable and the panel fails. You can try and apply some pressure right above the lines and see if they then disappear. Of course it is best done with the back of the TV removed. Here is an image to show you the TAB bonds.

There is really no fix for it since it requires a special repair. Sometimes it can be temporarily be resolved by continuing to apply pressure to the bond with some tape etc.

If you can, take some pictures and post those with your question. That way we can see what you see. Use this guide 在已经存在的问题里加入图片 for that
