Miner models: S9, S9i, T9, T9 +, L3 ++ - 5 videos!
In four videos, the S9 model board under repair and 1 S9i video board. The procedures are the same for the S9i and T9 models! For the T9 + and L3 ++ models, the signal manipulations are similar! In the video:
1. Test checking the correct passage of all chip signals. This must be done when we have all the signals and at the same time have a problem. In many cases, the S9, S9i, T9, L3 ++ models can only be restored in this way. Two videos on S9 boards use this technique with explanations.
2. All signals are in the "0 asic" log. In 2 videos, the repaired boards are S9 and S9i. This defect is a frequent guest of models S9, S9i, T9 +
3. All signals are in the "0 asic" log and the first chip is not to blame here! 1 S9 video added

1. The lack of chips. In the log shows 62 chips? and when replacing chips nothing helps? A common problem with the S9, S9i, and L3 models. The fact is that the miner program does not count one, two or maybe 3 out of 63 chips when scanning chips! The video explains in detail on the S9 board how to solve this problem, for L3 we carry out the same manipulations with the signals! + 1 video!
2. There are 63 chips in the log, and the hash is 0. In two videos, there are two ways out of several how to identify this defect! As far as possible there will be additions and other reasons. Repair boards in video S9 and T9. 1 video added!
