Chapter 8: Troubleshooting

General troubleshooting

Before calling a service technician, please check this chapter

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 (T1,

T2, T3, or T4). Set the closed caption feature to Off

(- page 49).

TV stops responding to controls

• 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.

Other problems

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

section or the recommended solution has not worked, use the

Restore Factory Defaults procedure (- page 40).

TV 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

• Check the antenna/cable connections (- Chapter 2).

•Press + on the remote control or TV and select a valid video

input source (- page 41). 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 48).

• If you are using a VCR, make sure L on the remote control

is set correctly (- page 21).

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

cable to the VIDEO 1 input at the same time

(- page 13).

Noisy picture

• If you are watching an analog channel (off-air broadcast or

Cable TV), you can set the CableClear

/DNR feature to AUTO

to reduce visible interference in the TV picture (- page 62).

Video Input Selection problems

• If the Input Selection window does not appear when you

press + on the remote control or TV, press + a second

time, which will change to the next video input source and

display the Input Selection window.

Cannot view external signals or channel 3 or 4

• If you cannot view signals from external devices connected to

VIDEO 1, VIDEO 2, ColorStream

, HDMI 1, HDMI 2, HDMI 3,

HDMI 4, PC or from channels 3 or 4, make sure the Input Lock

is set to Off (- page 55).

Poor color or no color

• The station may have broadcast difficulties. Try another

channel.

• Adjust the Tint and/or Color (- page 48).

Poor composite or S-video picture

• 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.

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 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.

LED indications while in reboot from standby

• When you plug the power cord in, the yellow LED will blink

until the TV enters standby mode, (plugged in but not

powered on). This is normal and is not a sign of malfunction.

Sound problems

• 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 51).

• 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 51).

• 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 51).
