Hi all. First time here. I got tasked with fixing my sisters dead iMac late 2012. It had a cracked screen with no display but you can hear it boot up and ping it once it's up. There's no shares of Remote access that was set up..
I got the replacement fused glass to LCD and everything was great until the new "apparently cheap" adhesive didn't hold the display to the case. It just fell off and pulled the ribbons out with it 2 weeks after the install. Don't let me leave out that it hit a chair falling to the floor and cracked it. anyways.
Here's my issue. Since the ribbons were so ruffly yanked out off the logic board, I checked them over and they and the connections on the board seemed fine. I reconnected everything and not only did the LCD not turn on, I smelled something burning. I immediately pulled the power. You will see the little melted chip in the attached pic. Does anyone know what that's for and what it controls? I was shocked since there's only one way to connect the cables.Where this chip or diode is I would think it has something to do with the LCD power ?????
Here's the status.
When the system is off, plugged in, the CPU fan is blowing at 100%. When I turn the system on the fan stops and it slowly works it's way back to 100% when the startup status bar is at 50% under the white Apple. Once booted up The process "Kernel_Task" is hitting the CPU at 400%. I'm able to see this with a thunderbolt to HDMI adapter connected to a 32" LCD TV I use as a monitor. The system is fine but too slow due to this process that's taking up the CPU. Anything thoughts? How can I stop this process from slamming the CPU?
Thank you,
Steve
