| + | [title] Confirm Mainboard Failure, Part 1 |
| [* black] Before replacing the mainboard, it is important to thoroughly troubleshoot the problem to ensure that it's the source of the issue. | |
| [* black] Normally, the mainboard produces a short beep about 10 seconds after powerup. If it doesn't beep, then it's probably dead. | |
| [* black] If the printer produces multiple or repeated beeps, it is a sign that the mainboard is likely functional, but there may be another component that has failed, such as a dead CMOS battery or bad memory. | |
| [* icon_note] Refer to Step 8 for further diagnosis. | |
| [* black] Another indication is the front display - If all pixels remain black, it may be an indication that the mainboard is dead. If the display does not light up at all, like in the photo, it may be a sign of a different issue, such as a dead power supply for the electronics module. |
