Black Screen after HD replacement
Hello, I was wondering about a repair that I had made on my EMC 2308 iMac late 2009.
I had the HD replaced at Best Buy. When I got home and powered it on it ran fine. however, the fans where running really hard. anyways, I found a site called Hdfancontrol.com and installed the program to monitor the hdd fan speeds, which it has worked great. But when I powered my iMac yesterday it ran for about ten minutes with a high pitch sound coming from the left top portion of the iMac. After another five minutes it powered itself down.
I felt the back of the iMac and it felt hot in the region I described. I took it back to Best Buy and said that the logic board might of fried out. But I am not buying it because the iMac powers up and boots. I can take a flash light and see images on the screen, so I know everything is running correctly. I was wondering if the tech might of damaged the V sync cable because I opened up the iMac and noticed that one of the pins on the cable was curled back, so I was able to pull the pin back in place an re-attach, but no luck.
So should I replace the V sync cable and the inverter board, or do you think its the logic board?
Any help would be appreciated because I am pretty stressed out about this whole thing.
Is this a good question?
