Is this fixable or do I need to send it in?</P> Mon, 28 Dec 2015 00:07:37 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/My-Canon-5D-II-s-back-light-will-not-go-off/m-p/159921#M24237 Jacqofhearts-10 2015-12-28T00:07:37Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/My-Canon-5D-II-s-back-light-will-not-go-off/m-p/159976#M24238 <P>As a last resort before sending it in to Canon for repairs, check the LCD illumination button, ....</P><P>&nbsp;</P><P><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/8638i735448D7D72A158E/image-size/original?v=mpbl-1&amp;px=-1" border="0" alt="5D_MkII_LCD_Backlight.PNG" title="5D_MkII_LCD_Backlight.PNG" /></P><P>&nbsp;</P><P>... and the associated illumination brightness setting in the camera's menus.</P> Mon, 28 Dec 2015 14:31:47 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/My-Canon-5D-II-s-back-light-will-not-go-off/m-p/159976#M24238 Waddizzle 2015-12-28T14:31:47Z
