My tv screen show half picture

@saman1726 first you need to determine if this is caused by the TV or a connected device (DVD Player,Game Console etc.), you do that by turning the TV on then press menu on your remote. If you can see the entire menu you know there is a problem with a connected device. If the entire menu cannot be seen, there is a problem with either the panel or the backlight inverter. I'd check the power board and all connectors first then the TAB on top of the panel. Those are the small ribbon cables that go inside the panel. Remove the back panel of your TV and post some images of your boards And the board layout and post those with your question. For that use this guide.Let us know what you find.
