Front Service

The following instruction will guide through the exchange of all replaceable parts.
All replacements require the removal of the Pixel cards first. Replacement of power supply and
Receiving cards require additionally the removal of the hub board.
Notice
 It is essential to wear a glove at least at the hand that might touch the front of the LED cabinet,
because the LEDs are very sensitive to the greasy film on the skin, and ensure ESD protection.
 Ensure the Service tool is charged properly before using it.

Change the Pixel Cards

The Front service takes only 10 seconds to exchange a pixel module. This convenience is due to
the unique magnet interfaces (A), corner click-pins (B) and Pixel card connector (C).

Notice
During the removal process, put your free hand below the Pixel card removal position, ready to
catch it.
By this, you can prevent the Pixel card from falling down in case the tool's battery dies or it
releases the Pixel card too early.
Step 1) Set the air pressure regulator on the Service tool to Max.
Step 2) Place Service tool centered on the Pixel card.
Step 3) Push the Service tool on a Pixel card and keep the red button pressed so the Service
tool holds the Pixel card firmly.
Step 4) Carefully pull the Service tool with the Pixel card horizontally and steady out of the LED
Wall.
