My antminer T15 stop working, i already check all boards and the PSU and found no problems at all, it just don't power up.

I remove all boards and leave only the PSU and the control board, same problem, no power up.

I test the control board with other PSU (APW3+) and is working perfect.

I open ther PSU, nothing burn, zero smell (i don't have the cov19 ok, hehe), everthing looks fine, i test the primary protections (varistors, thermistors, fuse, etc.) and evething looks fine, anyone have schematics? or any idea what happens with my PSU? it's the only one i have, is kinda sad after my T17 burn.

I still need check other components like a relay i found in the primary, i guess is part of the protection, is hard to check anything in the primary, is all glued, weird part is that the secundary have no glue.

It's a APW8.
