My Miner's hashrate is only 2/3

Common problem, yes I have read but I didn't find issue like this.

But my antminer finds all chains and it shows that all ASIC chips are 00000 00000 00000.....

All three green lights are on on control board.

I have upgraded latest firmware.

I have changed cords between hashboard and control board. The fault isn't in cords I think. If change J1 cord to J4 on control board problem follows. Miner stats only shows Chain#4 instead of chain#1 after that. Which is a good thing I guess.

Is it still possible that hashboard is broken or asic chips?
