I get no lcd when turning on my printer. It only turns on when I connect it to a computer. Why is this?

What is your printer type? What is the mainboard type?
How about swapping the connection of 2 cables behind LCD screen?

Sorry about that Gt2560, pro-c model, I put new printer drivers in the board. It successfully auto zeroed and I was preheating the bed to check it, turned off the printer afterwards and it would not turn back on unless I plugged it into computer. It previously turned on and was controlled by the lcd.

Is the "printer driver" you call stepper driver? If it is, is it as same as the older one?

I still don't understand. Is it Marlin firmware?
