Mac Mini Chime Loop - No Video
I am working on a Mac Mini. Late 2014
Machine was working fine. I took it apart using the guide here to install a larger SSD, it went smooth as butter. Put it back together and powered it on using a bootable High Sierra Jump Drive, It took longer than usual sitting on a black screen but it did come up. It got stuck on the Apple screen for quite a while. I pulled power.
Now ANY time I plug it in it just keeps giving me the power chime over and over and nothing on the screen.
I even try it without a hard drive plugged in and does the same thing.
SMC Reset does nothing.
Any advise? Thanks

UPDATE: The caps lock light does cycle and mouse does light up

Left machine unplugged all weekend. Came to work Monday morning and plugged it in. It sent power to the usb ports and the fan spins like usual - but I get no power on chime. There is nothing on the HDMI output. I let it sit for 30 mins and it did nothing. (at this point I put the old hard drive back in with a proper OS installed, so it should boot up and run). After 30 mins I pulled power for 30 seconds and plugged it back in and its back to the same chime / reboot loop. Any help would be great. Thanks

Would this device boot even if it could not see a hard drive of any kind? Perhaps I damaged the sata flex cable.
Now the startup chime has some distortion to it. Off
With this device, Should it power on automatically when I plug power in?
Update: The startup chime is clear as a bell WHEN THE WIFI CARD IS INSTALLED. Any time the wifi card is not installed it gets scratchy and distorted.
I think this logic board needs a exorcism!!
MAKING HEAD WAY! THE USB DRIVE I BOOTED FROM WAS A CLOVER DRIVE, I THINK IT CORRUPTED THE “ME REGION”

Just ordered a replacement power supply as a shot in the dark. Its the lowest cost option - Worth a shot.
