This is technical and it seems you don't have knowledge about repairing boards.

It's not measuring the voltage it's measuring resistance like the capacitors(The orange/brown color) for me with an analog multimeter I don't use exact Ohms if I see there is resistance on both polarity then I'm sure it's shorted but if you see no resistance then the capacitor is not shorted. Another thing to find those shorted parts in my own experienced is by injecting voltage and find what parts are hot.

In that case, you need to point the multimeter at the ground(The positive one) and the pins from 1,4, and 8(The negative one) to check if those MOS are shorted.

Without any knowledge about the basic repair, you will not understand the guide from ZeusBTC. You should learn the basic repair first

About your first question, since the image said downward then from the image, you need to start from 1 which is the first pin on the top left corner, and the 4th pin is on the top right corner then the 8th pin bottom right corner.

Oh I figured that out meanwhile. It's just because his explanation in English can get a bit confusing. He was talking about the output voltage and in the same sentence he said to measure the resistance. That's what confused me. His guide might use a better translation though, many confusing parts in the whole thing, but I'm managing to manouvre myself out of it. I just took a working hashboard, measured the whole thing out, and wrote the data down to compare to the malfunctioning boards. I'm getting there eventually

PS: I'm an industrial electrician, so the basic knowledge is more than present, just need to school myself a bit more in to electronics Wink

Another example: In his guide, he talks about the PIC reprogramming. I have a hashboard here that showed 2.5V on the second pin. He said if it's not at around 3.3V, you should reprogram the PIC. I ordered me a PICkit 3.5, ordered the HEX files from ZEUS, I did everything step by step and reprogrammed the PIC, now I got it at 2.8V. So still no 3.3V. But in the guide, it stops there. What if the reprogramming doesn't do the thing? Should I replace the PIC? Or does it mean I need to look elswhere for the problem? It's not that the PIC doesn't show anything. So if the PIC was bad, it would probably show 0V or am I wrong?
