Hey guys, I have another issue with my mid 2011 27' iMac a1312 screen not turning on. The computer boots and the OS is working, but the screen remains completely black. Even when shining a flashlight on the screen, there is no visibility at all. The screen had been blinking to complete black for second here and there through out the day for about 6 months before this issue. Inside the iMac when powered on 2 of the 4 LED indicators are lit up. From reading what others had said that means the screen is not receiving power if I'm correct. After digging around on the forums I found a couple possible solutions but still not 100% sure what the problem is. I just replaced the backlight inverter board ($20) and it still doesn't work. I also ordered a new v-sync cable to replace but I don't think that's the issue after reading around the forums more. Do you guys think it's just something in the LCD screen that blew out? I'm going to order a new screen on ebay soon and will update if that fixed it or not. Any feedback is greatly appreciated!
