TV Power On/Off
Symptom Remarks
1. TV takes an excessively long time to power
on. When powered on, the TV needs time to boot up, just as a com-
puter does. Also, the TV’s lamp requires a few moments to heat
up to full brightness.
2. You cannot program the TV to turn on auto-
matically (Timer function) The TV may be locked. •
The clock may not be set. •
3. TV turned itself off and the light on the front
panel started to blink. Momentary power fluctuation caused the TV to turn off to •
prevent damage. Wait for the green light to stop flashing
and turn the TV on again.
If the TV does not stay on, press the POWER button on the
•
control panel for at least eight seconds to perform System
Reset. If this happens frequently, obtain an AC line power
conditioner/surge protector.
An unusual digital signal may have been received, triggering a
•
protection circuit. Wait for the light to stop flashing and turn TV
on.
4. TV will not power off. Press the POWER button on the control panel for ten seconds
to perform System Reset.
TV Channels
Symptom Remarks
1. The TV takes several seconds to respond to
channel changes. It is normal for digital channels to take longer to tune in. •
Press ENTER after entering a channel number to avoid •
delays.
Use a 4-digit number for an over-the-air digital channel.
•
Use a 6-digit number for digital cable channels if your cable •
service is able to recognize 6-digit channel numbers.
2. You cannot access a channel. Use number keys instead of CHANNEL Up/Down. •
Be sure the channel you want to view is in memory. •
Check that the TV is switched to the correct device or •
antenna for that channel by pressing the ACTIVITY key.
Make sure the Lock > Parent menu lock is set to Off.
•
If you cannot tune to a virtual digital channel even though the •
TV has already memorized digital channels, tune to the physi-
cal channel number used by the broadcaster. The virtual
channel will then be automatically added to memory.
You may be trying to tune to an analog channel that is no
•
longer broadcasting.
3. When ChannelView list is displayed, informa-
tion appears incomplete Press INFO to update the display for the highlighted channel. •
Program information is displayed only for the currently tuned •
channel.

•
provider. No other data is available.
