LED 1 lights when I plug in the power. As soon as I touch the power button, LED 1 goes off, and nothing else. All LEDs are off. Unplug and replug and LED 1 lights. This indicates there's no problem with the power supply.
I'm fixing the oft-defective NVIDIA GeForce 8800 GS GPU. I reflowed the GPU and am in the process of seeing if the reflow worked. Before disassembly, the machine could turn on. Now nothing. During the process, I cracked the connector on the power inverter cable that goes from the power supply to the back of of the display.
In my interest to get my iMac together, I placed the single dangling wire on its pin, then placed the two intact sides of the inverter connector on either side. (Gluing the connector together just didn't work.) I plan to order a replacement cable as soon as I can.
Could this wonky cable connection cause the whole system to not function? I think it could, but thought I'd ask. Any other thoughts or gotchas from people who've done this type of work?
