| [* black] After powering up the printer, allow it to run for at least 10 minutes. Check the temperature of the board on the back side of the CPU (green arrow). If it is hot (> 50°C), this may indicate a burnt-out CPU. | |
| [* black] Additionally, you can check if the original CPU fan is functional. If it does not work, this may also indicate a burnt-out CPU. Refer to Step 9 for further instructions on how to check. | |
| [* icon_caution] Caution: The power inlet and wires are located above the mainboard. Be sure to exercise caution and take necessary safety precautions to avoid the risk of electric shock. | |
