i gave it to friend of mine to check it with one of his s11 ,same batch, control board,psu,fan and etc. and he is good in electronics.
it was control board , confirmed, now idk how i damaged it , because he didnt have a clue. prolly the thing philip said that they talk to each others
so as soon as the orders come i change it and i think im good to go.
thanks for the good information guys , i was totally freezed  

im not yet able to post pictures im newbie here and have to do more post for that feature
well i dont know maybe the fan was wrong or maybe when ive been struggling to fit the plug in i damaged the control board or maybe somehow something burned idk. and the first time i turned on the red light at the back where u plug the ethernet lan cable flashed briefly (or maybe also other lights came up but i dont remember) and when i switched off after that no light ever came up
do u see any probability that the hashboards are bad? or even without hashboard ,but even without hashboard the control board will light up , i did check with my other s11.

so
im waiting for a new fan and control board to arrive
i did the reset nothing happened
so my guess is with the control board , coz no lndicator and i even checked that i unplugged hashboards and tested again , same result

thanks bro

hi
ive tried new lan cable. nothing
i guess it is control board and i somehow damaged it , or maybe PSU , but i dont know how i could make psu broken,and as far as there is no light ( because u said if the fan is faulty i can access the UI)
but if the control board is burned well nothing comes up as the software is with the control board.

ive checked antminer website and ive found this as it is exactly my problem


so i change control board and Fan (coz fan was spiining bad at first ) then i update here

thanks a loooooooooot guys

ps : i have more s11 but im afraid i break them too ( im very bad at electronics ,im a mechanics guy) so i orderes a fan and control board. to check it out

hi
thanks for the fast replay
no i couldn't solve
i cant access the UI i mean it dosent show up on modem router ,
even when i replaced the original fan it is same, no indicator lights on , nowhere, only the fan are spinning
before i changed the fan all was good only the fan was noisy, is it possible that the fan connection plug was not right and which part will get the damage.
it never came up and after the first try which it was on and i was checking ip to access the UI from my pc, it was few minutes but when it was ok, after turning on the fan speed changed , it was spinning like idle low rpm and i couldnt access the UI via my pc , ethernet was not working, so i turned it off and it was very very cold,the hash board aswell, i followed the antminer website troubleshoot and unpluged hash boards , still the same, no lights but fan spinning idle mode.

hello

my antminer s11 fan was noisy so i took a new fan
the socket plug was not fitting so i changed it with the old plug but cutting the wires and attached them ( Secured) , then after i turned my miner on there was no indicator light at all and the new fan spinnned for a while ( like 2 minute or so to see if something is up ) and stopped other fan was still spinning , then i changed the fan to the old noisy one , this time the fan starts spinning (both of them).i checked all plugs and all connections.
no light on control board or hashboard, only few blinks on fault red light on the first time and after that no light at all. so i searched on google and came up with this on antminer website:
i have one more s11 but the control board of that one is diffrent, the faulty one has same control board as s9i ( which i have also) all is same but one cable ( in s9 there is one cable from psu to control baord , in s11 there is 2,one small and one big )

Issue: PSU can’t work but fan is running. All the indicators are off.

Reason: The control board cannot get power as the power circuit in IO board is damaged.

Solution: Switch the BB Board and IO Board with good miner to troubleshoot the defective parts.

so if it is so if i get a new fan and new control board ,will it work
or is it possible that i may damaged the hash board when i turned it on first time and waited few minutes, but hashboard was cold and no visual sign ,( in this case im screwed because i dont have that much money right now and i dont want to cash out btc to get new miner,just reached my short term goal amount and mentally i just cant sell)

sorry for bad english
and im figuring out how to post a pic as im new here

thanks

i would only change to BITCOIN the king
