600II system)
Subject: Dim Display
In the event you receive a DVD600II player with the complaint: “the display is too dim”, follow the
instructions below:
The DVD600II has a dimming feature that may be ON; this should be checked first. On the front panel, left of
the display, is the dimmer button. With the unit ON, press the button repeatedly and cycle through these
stages in the following order: FULL BRIGHTNESS
> HALF BRIGHTNESS > OFF > FULL BRIGHTNESS.
If the FULL BRIGHTNESS setting is still dim,
In the Front panel PCB, replace C903 (0.1uF 50V SMD capacitor).
1) Remove (8) screws holding the top cover on; remove the cover.
2) Remove the five plated screws holding the front panel to the chassis (one is on the bottom)
3) Unplug the single 5-pin Molex plug to CN906 (near the power switch) to allow the front panel to be
disengaged from the chassis; cut and remove any cables ties, but note their location.
4) Remove the front panel from the unit; there are four tabs/catches that must be freed as the panel is
removed; two are on the sides and two are on the bottom.
5) Once the rear of the front panel PCB is exposed, locate C903, 0.1uF 50V SMD capacitor. Replace with
JBL part# 2026729091.
6) Replace any cable ties that were cut; reassemble and test the unit.
