Chapter 7: Troubleshooting
General troubleshooting
Before calling a service technician, please check this section 
for a possible cause of the problem and some solutions you can 
try.
Black box on screen
The Closed Caption feature is set to one of the Text 
modes (T1T2T3, or T4). Set the Closed Caption 
feature to Off (- page 32).
Monitor stops responding to controls
If the monitor stops responding to the controls on the 
remote control or monitor control panel and you cannot 
turn off the monitor, press and hold the POWER button 
on the monitor control panel for 5 or more seconds to 
reset the monitor.
Monitor will not turn on
Make sure the power cord is plugged in, and then press 
p.
The remote control batteries may be dead. Replace the 
batteries or try the control panel buttons.
Picture problems
General picture problems
Press + on the remote control or INPUT on the monitor 
control panel and select a valid video input source (- 
page 25). If no device is connected, no picture will 
display when you select that particular input source. For 
device connection details, see page 10.
Adjust the picture qualities (- page 29).
If you are using a VCR, make sure L on the remote 
control is set correctly (- page 18).
If you have two VCRs connected to your monitor, make 
sure you have not connected the same VCR to the 
monitor’s output and input connections at the same time.
Do not connect both a standard video cable and an 
S-video cable to the VIDEO-2 inputs at the same time 
(- page 13).
Noisy picture
If you are watching a tuned analog channel (off-air 
broadcast or Cable TV), set the CableClear
®
/DNR 
feature to Auto to reduce visible interference in the 
monitor’s picture (- page 31).
Video Input Selection problems
If the program list does not appear when you press + on 
the remote control or INPUT on the monitor control 
panel, press the button a second time, which will change 
the monitor to the next video input source and display the 
program list.
Poor color or no color
Adjust the Tint and/or Color (- page 30).
When the ColorStream
®
 signal source is active, the 
VIDEO OUT terminal outputs blank video. To receive 
video from the VIDEO OUT signal, a standard video or 
S-video IN terminal must be used instead of the 
ColorStream
®
 connections.
Poor composite or S-video picture
If the image is poor when the monitor is connected to an 
external A/V device (e.g., DVD player, video game 
system, set-top box, etc.) try using a ColorStream or 
HDMI video connection instead.
Picture and sound are out of sync
As with all products that contain a digital display, in rare 
instances, when viewing certain content (e.g.. television 
broadcasts, video games, DVDs), you may notice that the 
sound and picture are slightly out of sync. This 
phenomenon can be caused by various factors including, 
without limitation, video processing within the monitor, 
video processing in an attached gaming system, and 
video processing or different compression rates used by 
broadcasters in their programming. You may want to try 
one or more of the following suggestions, which may 
help to reduce the effect of this phenomenon:
– If the monitor is connected to an A/V receiver that 
has a programmable audio delay feature, use this 
feature to help synchronize the sound to the picture. 
– If you notice this phenomenon only on certain TV 
channels, please contact your local broadcast, 
cable, or satellite provider to inform them of this 
issue.
Sound problems
The sound may be muted. Press VOLUME
Remote control problems
Make sure the remote control is set to the correct device 
mode (- page 18).
Remove all obstructions between the remote control and 
the monitor.
The remote control batteries may be dead. Replace the 
batteries (- page 16).
The monitor’s remote control may not operate certain 
features on your external device. Refer to the owner’s 
manual for your other device to determine its available 
features. If the monitor’s remote control does not operate 
a specific feature on the device, use the remote control 
provided with the device (- pages 18–22).
