Replacing The Dc Fan (Hdcu1500) - Sony HDCU1000 Maintenance Manual

2-2-2. Replacing the DC Fan (HDCU1500)

c
If the fan is defective, the temperature inside HDCU1500
will rise. Touching the inside of the unit in this state may
cause a burn.
Replace the parts after turning off the power and cooling
the inside.
The fans that are used in the rear panel of the unit are
recommended replacement parts.
The lifespan of these fans is about 30,000 hours, which
means that the fans can be used for about three and a half
years if the power is on all the time, so as a guideline the
fans should be replaced every three and a half years.
1. Turn off the main power and disconnect the plug from
the outlet.
2. Remove the power supply unit.
(Refer to Section 2-2-1.)
3. Remove the three screws and remove the fan from the
power supply unit.
4. Disconnect the harness for the fan from the connector
J4.
