28 ML5000 Service Manual
The Stereo Slave PCB must be removed before the following PCBs can be removed; Mono Fader,
Master Fader Centre, Master Fader L/R & Control Panel.
1) Cut the 2x Cable ties attaching the Stereo Slave PCB onto the Mono Fader & Control
Panel PCBs.
2) Carefully remove the Stereo Slave PCB by pulling it upwards.
3) Once removed, turn the Stereo Slave PCB over.
4) To remove a PCB, use a 5.5mm spanner to remove the relevant M3x4 Taptite Hex Headed
Screws that attach the PCBs to the Master Fader bracket.
5) To remove a fader, remove the two relevant M3x5 Countersunk Pozi Screws with underhead
pips (H) as shown in fig.4. Then unplug the fader wireform from the Stereo Slave PCB, the
fader can now be removed. De-solder the three fader wireform wires from the fader, taking
note of the wire positions for refitting.
6) Removal of the ‘H’ shaped Control Panel PCB can only be achieved once the vertical
section of PCB has been removed. Once the vertical section has been removed, remove the
2x M3x6mm Pan Pozi Black screws attaching the ‘H’ shaped Control Panel PCB to the fader
bracket. The ‘H’ shaped Control Panel PCB can then be removed.
10) To remove the Mute Group PCB, use a 5.5mm spanner to remove the two screws attaching
the PCB to the fader bracket.
The VCA Master Slave PCB must be removed before the Master Fader PCBs can be removed.
11) Cut the 2x Cable ties attaching the VCA Master Slave PCB onto the Master Fader PCBs.
12) Remove the 15way Flexi cable running between the VCA Master Slave PCB and the Mute
Group PCB.
13) Carefully remove the VCA Master Slave PCB by pulling it upwards.
14) Once removed, turn the VCA Master Slave PCB over.
15) To remove a PCB, use a 5.5mm spanner to remove the relevant M3x4 Taptite Hex Headed
Screws that attach the PCBs to the Master Fader Bracket.
16) To remove a fader, remove the two relevant M3x5 Countersunk Pozi Screws (H) from the
Master Fader front panel (see fig.4). Unplug the fader wireform from the Stereo Slave PCB,
the fader can now be removed. De-solder the three Fader wireform wires from the fader,
taking note of the wire positions for refitting.
Note: A fader can be removed without removing the IDC wireforms and Slave PCB.
17) To refit any of the PCB assemblies, follow the above procedure in reverse order. Make sure
all harnesses are aligned and plugged on. Test for correct operation.
