| [* black] The electronics module is very complicated and many other things can fail. So you need to verify that your printer really has bad mainboard and not something else. | |
| [* black] Normally, the mainboard produces a short beep about 10 seconds after you powerup the printer. If it doesn't beep, then it's probably faulty. | |
| [* black] Another indication is the front display - if it lits 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 example). |
