Here are some solutions for a 3D printer with an unresponsive LCD:
- Connect to the LCD screen’s right port.
- Set Your 3D Printer’s Correct Voltage.
- Change your SD card.
- Turn the printer off and unplug it.
- Ensure that your connections are secure and that the fuse is not blown.
- Update the firmware.
- Speak with your seller and request replacements.
Connections
One frequent cause of an unresponsive screen on the Elegoo Mars 2 Pro is the incorrect placement of the LCD wire. Connecting to the proper port should usually resolve this, particularly if the printer’s screen isn’t even turning on. You can also see if there are any cables detached from the mainboard. It may be that the power supply plug-ins have short-circuited, in which case they will appear melted or sparking.
Many users reported that once their cables were plugged in properly, they were able to use their touch screens like normal again.
But please make sure that before you examine these connections, make sure to turn off the printer from the power safely to follow safety precautions.
Voltage
Typically, the 3D printer’s voltage switch can be set to 115V or 230V. The voltage you choose depends on the area in which you live.
You should set the voltage to 115V if you reside in the United States, and if you live in the UK, you should crank it up to 230V.
Again, confirm the voltage that must be set based on your location. Your electrical grid forms the basis of the voltage number. Many consumers are unaware of this and consequently encounter touch screens that are unresponsive.
Some users claim that by using improper voltage, their 3D printer not only showed a blank screen on the LCD interface but also, a short time later, blew up the power supply.
SD Card
A popular repair for unresponsive touch screens has been reported by numerous users in relation to their SD cards. The LCD screen was going blank because they were using a fried SD card that had quit working.
You can check to see if this is the situation with your printer by turning it on without the SD card and observing whether it starts up normally. If it happens, all you have to do is purchase a new SD card for your 3D printer.

Rebooting
By shutting the printer off, unplugging everything, leaving it alone for a few days, and then plugging everything back in, some customers have had their screens start working again. However, someone who attempted this ultimately purchased a new motherboard, suggesting that this may only be a temporary remedy.
Firmware
Reflashing your firmware may be the answer if you’ve attempted numerous repairs without success.
Many customers have encountered an unresponsive touch screen as a result of the firmware, whether it wasn’t flashed correctly, there was an issue in one of the key configuration files, or you flashed it by accident and weren’t aware of it.

Reconnecting with the manufacturer who sold you the 3D printer and explaining your problem to them is one strategy that has proven successful for customers without costing them any money. After answering a few simple questions, you might be eligible for replacements under warranty and customer service.
