@vokreshidze those type of screen errors originate commonly with the LCD driver board (part of the panel). Connect an external monitor and see if that displays properly. If so, you know your GPU should be okay and the error is your screen. You will have to use the model screen that is meant for your model since the connections on the screen will not match. Connectors could be the same but internal wiring should be different. Of course if in doubt check for the datasheet of both screen and validate that.
