LED Display Driver board broken - why?
So I replaced the harddrive to a 1 TB SSD, using OWC Thermometer. Cleaned the interior, especially the vents that were very dusty.
Reassembled it. Turned on the iMac, everything worked fine. Formatted the drive, let it install Mavericks. Came back after 20 Minutes and see that LCD backlight is not working. I can see that the LCD works though. IMac was hot, but it had a good work to do (installing Mavericks), so nothing special.
Disassembled iMac again, all cables were properly installed, not broken.
But my nose smelled something broken. PSU is okay, no damages visible.
But LED driver board seems not okay. One of the three cubic things on it (SuperCaps? - DN680 1016 written on it) is just hanging, might have had a hot time, the tin melted obviously.
So my questions is: why did it melt? I don't want to spend 100 Bucks to buy a new one just to destroy it once again. Do you think it's possible just to replace the broken part? What is it exacly? I couldn't find one on the web using the written description on it.
Thank you very much for any help.
Is this a good question?
