Service and maintenance 47
VDO Face 5™ video panels use a modular block LED system that allow modules to be removed and
replaced for artistic or repair purposes. Modules are held in position by magnets and are hot-swappable, so
they can be replaced in a matter of seconds in the middle of a show, even if power is applied and a P3 signal
is present.
Blocks are supplied as either Left or Right (as viewed from the front, audience side) units and are marked
LEFT or RIGHT to identify them. Install only the correct type of block on each side of the panel.
Removing an LED block
There are two methods for removing an LED block from a panel. See (A) and (B) below.
(A) If you have access to the back of the panel:
1. See Figure 39. Take hold of the handle on the back of the LED block and push the block towards the
front of the panel until it is disconnected from its multiconnector and released from its magnetic holders.
2. Unclip the carabiner hook (arrowed) on the LED block safety wire and lift the block away from the panel.
(B) If you do not have access to the back of the panel:
1. Obtain a VDO Face LED Block Removal Tool available
from Martin® (see “Accessories” on page 51).
2. See Figure 40. Screw the prongs (arrowed) on the ends
of the Removal Tool into the corresponding holes in the
front of the LED block, then lift the block away from the
panel.
3. Unclip the carabiner hook on the LED block safety wire
and lift the block away from the panel.
Installing an LED block
To install an LED block:
1. Align the block so that the safety cable attachment
bracket is pointing upwards and the multi-connector on
the back of the block is pointing in towards the center of
the panel.
2. Fasten the safety wire in the panel to the attachment
bracket at the top of the LED block.
3. Depending on whether you have access to the front or
rear of the panel, use the removal tool shown in Figure
40 or the handle shown in Figure 39 to reinstall the
block. You will need to use a little pressure to reconnect
the LED block’s multi-connector, but do not use
excessive force.
