Power Supply Unit Change
SYMPTOM
Three types of power unit have been launched during production.
SOLUTION
• To improve the harmonics current of the AC power line, the power unit circuit for the listed 26” models has
been changed. Only parts with part number suffix -61 must be used.
Ref. Not OK OK
R630 Power unit (22 Ohm)
1-474-163-21
Power unit (330 Ohm) 1-474-163-61
1-474-163-51
• However, *-21 and *-51 Power Supply Units marked with a green or blue dot have been modified to 330 Ohm.
Therefore, this type of PSU can also be used for 26” models. This implies that a PSU with a green or blue dot
marking cannot be used anymore for 32” models.
NOTE: Only replace to a *-61 part in case replacing the Power Supply Unit is necessary for repair.
