Dear friends,
recently my single 60GHs miner from bfl labs stops working. I need some technical advice here.
Before one week my miner stoped. I 've noticed that both the PC and the miner is dead too.
The PSU of miner (the black bfl labs psu) has catch up fire and burns the PCB.
When i fix the PSU and measure it the output was 13,8V DC at 20 amps current rate.
I 've tried to power the miner and the device starts blowing at first and after it stops spining the fans and remains at low speed
which is normal. So far so good.
But unfortunately when i connect the miner to a host PC the USB section of device doesn't work.
I notice a small resistance beetween pin 6 of the FTDI chip and ground.
When i put this IC off the PCB the small resistance goes off to.
I 've already order a new one FTDI chip from ebay.
My question is: What do i need to put the miner in working mode again? Do i need to program the new chip and how can i do that?
I have a multi programmer for some EPPROMS and PICS too but i don't know if i can do it only with that.
Any help would be appreciated.
TIA
