Linn 328A - Manual (Page 6)

Installation & Operation
3-K DRIVER ARRAY REMOVAL AND REPLACEMENT
The 3-K driver array can be removed by unscrewing the
seven M4 retaining screws and carefully withdrawing the
unit directly away from the baffle until the built-in
connector at the back of the unit disengages.
Replacement is a reversal of the above procedure, taking
care to tighten the retaining screws no more than is
necessar y to hold the driver array firmly in position (set
torque driver to 200 cNm if used).
FUSE REPLACEMENT
The fuse is a time delay type. Always replace with a fuse
of this type and rating (see the Technical Specification
section). If the fuse repeatedly blows within a shor t time of
being replaced, please contact Linn for advice.

CLEANING

cleaning. Remove dust and fingerprints with a soft, dr y
cloth. Avoid using domestic cleaning products on the unit.
Servicing
Quick and easy maintenance was foremost in the design
brief for this monitor and therefore the drivers use modular
mounting arrangements so that they can be replaced
without the need for special tools or specialist personnel.
The replacement procedures are outlined below but fuller
versions (including explanator y graphics) can be supplied
on request.
LF DRIVER REMOVAL AND REPLACEMENT
An LF driver can be removed by an experienced technician
following the procedure below. This is most easily carried
out with the front of the monitor facing upwards.
1. Carefully remove the rubber trim ring covering the
rim of the grille, taking care not to damage the front
panel.
2. Unscrew and withdraw the eight M5 retaining screws
using a No.25 Torx driver-bit.
3. Carefully remove the grille.
4. Withdraw the driver unit until the two cable
connectors are exposed.
5. Cut all cable ties securing wires to the driver
chassis, taking care not to damage any of the wires.
6. Unsolder the cables from the driver terminals,
taking careful note of how the connections are
made.
7. Disconnect the 3-way JST connector to free the unit.
Replacement is a reversal of the above procedure,
taking care to remake the driver connections
correctly.
Damage to the driver may result when the unit is
switched on if these connections are remade
incorrectly.
Tighten the retaining screws no more than is
necessar y to hold the driver firmly in position.
