1st, please disconnect 1 of the hash PCB from the PCI-E power plug and try to operate with 2 hash PCB instead of 3.  (If your S7 shuts down after a few minutes or not.)  If the PSU was not strong enough, your 2 hash PCB method may let you keep mining without the unit being shut off or stop hashing in a few minutes.

If the above does not work, please try hashing with 1 hash PCB at a time.  You may have a damaged hash PCB in the mix and it could be interrupting the other PCB to hash.

If none of the above works,

Please try updating to the newest firmware.

If the firmware update does not fix it, it is time to send it in for repair!

I have a similar situation. My s7 batch 19 was hashing fine for a week. Not it has a solid green light instead of a blinking (hashing) green light. When I log into system it says 0.0gh/s. Everything else appears normal and fans are blowing. I've tried a hard reset with paper clip but I guess I'll try the above too. Do I have to backup the image before trying a firmware update? Is an SD card required for firmware update? Thanks!
