problems with screen image using SD

Good days guys, i have problem with my GLCD 128x64 and SD module, when my arduino communicate with MOSI, MISO and SCK, The display shows two horizontal lines throughout the 128 pixels on that drawing, the SD module and GLCD screen are connected using the same SPI communication pins only pin CS are in different pin for each of the modules, way the screen is not affected? may be assigned alternative pin to set the SPI communication and separates the SD module of the GLCD screen? or how i do to resolved this
