You may encounter some problems like black screen or white squires while using Anet A8 3D printer. Don't worry, follow this guide to solve the problems.

The Anet A8 printer's LCD screen went black.

Black screen problem is a common problem for all devices with displays. Here is the black screen image of Anet A8:

To solve the problem, just follow the steps below:

Step 1. Check power supply

A. Check the power indicator, if the light is on, move to Step 2.

B. If the light is off, check the wire connection & voltage selection if they are correct.

C. If the light is off and they are correct, you need to replace a power supply.

Step 2. Check mainboard

A. Check if the 40 x 40 fan is running. If not, please check the wire connection between power & mainboard is correct and the wire is not loose.

B. Click Reset Button on the mainboard, then check the D1 indicator:

- If D1 lights on for a second then went out and the screen is black, try to reconnect screen wire for several times, if still not working, you need to replace a screen.

- If the D1 indicator is always off and the screen is black, you need to replace a mainboard.

You need to check Anet A8's mainboard - click reset button and check the D1 indicator:

- If the D1 indicator is always off and the screen is full of white square, you need to replace a mainboard.
