Attention: the following instruction only applies to fixed-frequency miners such as DR5 and D5. If your miner is auto-frequency (e.g., S11, S15,T15), we need to receive the complete unit for repair because we cannot guarantee the miner will work well with the repaired board unless we test the complete unit in our facility. 
 

Tools required:

• Cross screwdriver (4mm diameter)
• Hexagon screwdriver (3mm diameter)
• A pair of gloves for protection purpose
