Screen change color vertically after device wake up from dim or sleep
My lenovo smartphone s650 screen turn from normal to grey lines vertically after few second. the screen is normal when display just start up or dim but gradually changes after a while. the lines are not permanent but depends on graphic on screen. for example if the device show battery charging at centre with black background, it starts changing from normal colour to grey vertical lines across where the image is. my first thought it may belcd problem but i need second opinion just in caseit was cable or logic board problem.
Es esta una buena pregunta?
