	[title] Verify it's really bad mainboard, part 1
	[* black] The electronics module is very complicated and the mainboard is not the only component that can fail. So first 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 powerup. If it doesn't beep, then it's probably dead.
-	[* black] If it beeps more than once or beeps repeatedly, then the ~~CPU~~ works, but something else failed (dead CMOS battery, bad memory etc). In that case you can diagnose it like in Step 8.
+	[* 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).
