Posted on October 29 2021

Please note that LCD is a consumable item, it may need to be replaced after a certain period of time. In this article, we’ll guide you through the steps of replacing the LCD on the Phrozen Sonic Mega 8K:

Step 2: Unscrew 4 screws on both sides and then remove 4 screws on the touch panel. Then remove the front casing.
Step 3: Unplug the USB connector and move the front casing away so that you can easily conduct the following steps.
Step 4: Unplug the following connectors carefully. First, unplug the four green connectors marked with numbers 1 to 4. Then, unplug the two white connectors beside the green connectors. Lastly, make sure to remove the black network connector on the side.
Step 5: Unscrew the three corners screws on the mainboard and remove it.
Step 6: Unplug the LCD ribbon cable from the board.
Replace the LCD
Step 1: Remove tape from all 4 sides.
Step 2: Remove the old LCD.
Step 3: Unplug the ribbon cable from the old LCD screen. If this is your first replacement, you may remove the hot melted adhesive. Note: The adhesive is used to protect from shipping accidents.
You can use a cotton swab to apply sanitizing alcohol on the edges to soften the glue on both the LCD screen and the CHITUBOX mainboard. Once the glue has been softened, the ribbon cable can be removed easily.
Step 4: Remove the plastic packaging from both sides of the new LCD screen.
Step 5: Plug in the ribbon cable into the new LCD screen.
Step 6: Place the new LCD. Phrozen's logo should be present on the front side. Then insert the ribbon cable into the gap next to the glass where the LCD screen is placed. Please make sure the ribbon cable doesn't block the LED lights.
Step 7: Tape down all 4 sides. As there is a gap present in the front, you’ll need to use a larger piece of two or tape the area down twice to make sure that the gap has been sufficiently covered. Your new LCD screen has now been perfectly fit into the 3D printer!
