Toshiba 40XV648U Mode D'Emploi

Before calling a service technician, please check this 
chapter for a possible cause of the problem and some 
solutions you can try.

• The closed caption feature is set to one of the Text 

modes (T1, T2, T3, or T4). Set the closed caption feature 
to Off (- page 40).

• If the TV stops responding to the controls on the remote 

control or TV control panel and you cannot turn off the 
TV, press and hold the POWER button on the TV control 
panel for 5 or more seconds to reset the TV.

• If your TV’s problem is not addressed in this 

Troubleshooting section or the recommended solution 
has not worked, use the Reset Factory Defaults 
procedure (- page 31).

• 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.

• Check the antenna/cable connections (- Chapter 2).
• Press + on the remote control or the TV and select a 

valid video input source (- page 32). If no device is 
connected to a particular input on the TV, no picture will 
display when you select that particular input source. For 
device connection details, see Chapter 2.

• Antenna reception may be poor. Use a highly directional 

outdoor antenna (if applicable).

• The station may have broadcast difficulties. Try another 

channel.

• Adjust the picture qualities (- page 39).
• If you are using a VCR, make sure L on the remote 

control is set correctly (- page 23).

• Do not connect both a standard video cable and an S-

video cable to the VIDEO 1 input at the same time (-

page 13).

• If the Input Selection window does not appear when you 

press + on the remote control or the TV control panel, 
press + a second time, which will change to the next 
video input source and display the Input Selection 
window.

• If you cannot view signals from external devices 

connected to VIDEO 1, VIDEO 2, ColorStream HD1, 
ColorStream HD2, HDMI 1, HDMI 2, HDMI 3, PC or 

from channels 3 or 4, make sure the Input Lock is set to 
Off (- page 46).

• The station may have broadcast difficulties. Try another 

channel. 

• Adjust the Tint and/or Color (- page 39).

• If the TV 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.

• If you connect an S-video cable, be sure to disconnect 

the standard (composite) video cable. Do not connect 
both types of video cable at the same time.

• 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 TV, 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 TV 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.

• Check the antenna/cable connections (- Chapter 2).
• The station may have broadcast difficulties. Try another 

channel. 

• The sound may be muted. Press VOLUME.
• If you hear no sound, try setting the MTS feature to 

Stereo mode (- page 42).

• If you are not receiving a second audio program from a 

known SAP source, make sure the MTS feature is set to 
SAP mode (- page 42).

• If you hear audio that seems “incorrect” for the program 

you are watching (such as music or a foreign language), 
the SAP mode may be on. Set the MTS feature to Stereo 
mode (- page 42).

• If you connect a PC using either the PC IN terminal or an 

HDMI terminal, make sure that the PC Audio setting is 
properly set (- page 47).

• Make sure the remote control is set to the correct device 

mode (- page 23).

• Remove all obstructions between the remote control 

and the TV.

• The remote control batteries may be dead. Replace the 

batteries (- page 19).
