harman/kardon Service Bulletin
Service bulletin # HK2004-03 October 2004 Warranty labor rate: MINOR repair
To: All harman/kardon Service Centers
Model: DVD22
Subject: Locked in POWER ON
In the event you receive a DVD22 with the complaint: “The unit will turn ON with “POWER ON” in the
display, but the unit is locked up and will not read a disc, nor will pressing any button accomplish
anything, even the Power button”, follow the instructions below.
(Behavior is intermittent; unplugging the AC power cord and replugging the unit in will sometimes reset it.)
Synopsis: Add a 4.7K ohm resistor to the indicated area on the bottom of the Main PCB.
CAUTION: The DVD22 is an electrostatically sensitive unit and can be damaged by careless handling; you
must follow proper static control procedures to prevent damage to the DVD player.
1) Remove the eight plated screws holding the top cover to the unit; remove the top cover.
2) Remove the four molex connectors and one small FFC cable from the Main PCB.
3) Remove the five plated machine screws (top) and the five black screws (rear panel) from the Main PCB.
4) Remove the Main PCB from the unit.
5) On the reverse side (bottom), solder a 4.7KΩ1/8W resistor (h/k part#299-4.7K or WLD5.630.472) to the
indicated area. (Attach one end of the 4.7KΩresistor to one end of CB407, the other side, to a small
through-hole pad near the silkscreen label “CB410”).
6) Replace the Main PCB and assemble the unit in reverse order.
7) Test the unit.
