@bheimer you are not telling us what you have checked etc. I would start by checking the fuse on the power supply. See if it has continuity. After that, you will need to check for power distribution. Something like this document [document|30566] will help you with the troubleshooting. If you have any issues while you are working on it, you can always elaborate in comments and post images with YOUR QUESTION
That way we can see what you see.
