Do you have an extra s19 pro? If you have, try to use it to test the PSU.
If you don't have one, try to physically check the control board and check the power terminal and plug if there are burn parts.
If there are no burn parts under the socket or the wire try to flash it with the latest s19 pro firmware from Bitmain and make sure you directly plug your miner on the wall outlet. I'm not 100% sure if it can solve the problem but just try it.
If nothing works then you have a defective PSU and it needs to replace with a working PSU.
Now its running without anyline on
What do you mean about this? Is that the data cable from the control board to hashboard?
