Chosen Solution

Just replaced my broken optical drive following the directions via the tutorial here. The repair went smoothly but now there is no power at all. Pressing the power button does nothing and neither does attempting to power on the console with the controller, either wirelessly or plugged into a usb port. I don’t see any visible damage to the ribbon cable and don’t see anything unplugged or otherwise damaged, there is just no power. Has anyone else experienced this? If so how did you fix it?

Ok, after another once over and further dismantling it turns out that the 10 pin connector leading from the optical drive to the board was able to be inserted backwards (on the side connecting to the optical drive) and prevented the console from powering on. The drive was purchased from EP game supply on ebay and required me to plug the cable in upside down when compared to the OEM hardware. Anyone else attempting this repair with this hardware keep an eye out for this issue.
