Servicing, Installation & Operation | Linn 328A instruction

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 explanatory 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 necessary to hold the driver firmly in position.

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 necessary 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 short time of being replaced, please contact Linn for advice.
