The Ultimate Guide To antminer hashboard repair

3 Around the pulse signal. Purple is B (BI, BO) signal circulation,) signal circulation, from 00 chip to chip to 62 reduced degree; no reduced degree; no low level; no low level; no IO line It is 0V throughout standby, and also is a pulse signal of regarding 0. 3 at the time of computation.

> Red line is the circulation instructions of RST signal, signal circulation direction, signal flow direction, from IO port 15 foot, after that from, after that from, then from 00 chip to 62 chip transfer chip transmission chip transmission; no IO signal, standby It is 0V during standby, and is calculated throughout procedure.

In this Bitcoin ASIC repair stream, we have a large number of Antminer S19 hashboards from Bitmain that we need to repair. These boards ran in the harsh Texas climate in Rockdale. They burned out the TPHR90-03NL mosfets and are badly corroded on the temperature sensors and surrounding area. Most of them have completely corroded parts and pads that cause problems. Watch this stream to see how we fix these ASIC hashboards

8V when determining. 2. 2 Figure 3 shows the vital circuits on the front of the S9 hash board. number 2. inter-chip test factors 1) examination points in between each chip (After focusing the image listed below): number 2 During upkeep, the test factor in between the test chip is one of the most straight the fault location setting of the connection.

S9 Secret circuits on the front of the Operation board Note that: Due to the fact that the version of the S9 hash board is not specifically the exact same, the LDO-1. 8V power supply of the very early voltage domain names is powered by a different peripheral antminer repair LOD power supply chip for each and every of the three voltage domain names.

8V, DC-DC Outcome and also boost 14V Voltage. Discovery technique: 1) Do not connect IO line, plug only 12V: DC-DC result is around 9V, the boost result voltage is around 14V. Test factors must have LCK= 0. 9V, RI =1. 8V voltage, various other test voltages is 0; 2) Plug in IO, when you do not push the examination secret, DC-DC No voltage result with boost, after pushing the examination secret, PIC start functioning, currently DC-DC outcome photo, image device test program establishes the voltage, rises with the functioning voltage.

At this point the typical voltage of each examination factor must be: CLK: 0. 8 V, test tool sends out work, CO Since it's adverse. The DC level will certainly be pulled reduced, Instant voltage is 1.
