| [title] Verify it's really bad mainboard, part 1 | |
| - | [* black] |
| + | [* 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 it beeps more than once or beeps repeatedly, then the mainboard works, but something else failed (dead CMOS battery, bad memory etc). In that case you can diagnose it like in Step 8. |
| - | [* black] Another indication is the front display - if it lights up but all pixels stay black like in the photo, then it's likely the mainboard is dead. If it doesn't light up at all, then there is some other problem (dead power supply for the entire electronics module, for example). |
| + | [* 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. |
