How to determine which voltage domain is normal when the L3+ hashboard has voltage domain imbalance?

Z11 hashboard is short-circuited to ground at 3.3V. After removing the IC (U3), inductor (L1) and capacitors (20, 22, 23, 24), the short circuit issue persists.

S9 hashboard report 0, No RI signal, replace chip 62 and chip 63, power on but still no signals.

The tester is normal, but machine is not working, and the log shows that the count is wrong. How to solve it?

S9 hashboard the voltage and resistance are both normal, replace severial chips but stil report 50.

The S9 hashboard report asic 62, replace the 62nd chip but still the same problem still exists.

The S9 hashboard report 0, the domain voltage is 8V and there is short circuit domain.

When testing the S9 board, as soon as the DC-DC is powered on, the hashboard immediately power off.

S9 report asic 0, each domain voltage 0.37V up to 0.57V after reprogramming PIC

What the problem shows in the picture? The hashboard is broken.

Two hashboards of S9 both passed the single-board test, but the whole miner only had 2Th/s, one of the two boards without hashrate.Testing with an extended ribbon cable yields normal results.

S9 Miner status shows one hashboard ideal hashrate over 7,000 GH/S, but activate high-temperature protection. Reprogram the PIC, the same error.

All the T9+ hashboards can be detected,but all without hashrate.

Single board test result keeps showing "check", without any specific result.Tested many times always the same.

T9+ hashboard, 12V normal, 3.3V normal, MOS, PIC, power management chip are all normal, but no 9V output.

The single board test is fine, but it cannot achieve the required hashrate.

Chain 1 has low hashrate, pass single-board test OK,but reports temprature 15°C
