9.5 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 face 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.
