Hi there, I recently installed a new SSD into our 2011 iMac to replace the hard drive. All was working fine, however since screwing the LCD back in, the screen flickers consistently. The brightness is set at maximum, if I reduce the brightness using the keyboard, the screen goes fully black. However I can still see an image behind by using a flashlight directly over the screen. I assume the backlight is not working. I also purchased and installed a new display ribbon cable however that has not worked. Can anyone suggest anything? Thanks
