Chapter 8: Troubleshooting

Channel tuning problems

Make sure the remote control is set to the correct device

mode ( page 21).

The channel may have been erased from the channel

memory by the

Channel Add/Delete feature. Add the

channel to the channel memory ( page 30).

The channel may be blocked by the

Channels Block

feature. Unblock the channel ( page 47).

If you are unable to tune digital channels, check the

antenna configuration ( page 29). If you are still

unable to tune digital channels, clear all channels from

the channel list ( page 31) and reprogram channels

into the channel memory ( page 30). If you are still

unable to tune digital channels, use the Reset Factory

Defaults procedure ( page 33). Also see “TV stops

responding to controls” and “Other problems”

( page 53).

Closed caption problems

If the program or video you selected is not closed-

captioned, no captions will display ( page 42).

If text is not available, a black rectangle may appear. If

this happens, turn off the closed caption feature

( page 42).

A closed-caption signal may not display correctly in

the following situations: a) when a videotape has been

dubbed; b) when the signal reception is weak; or c) when

the signal reception is nonstandard ( page 42).

Rating blocking (V-Chip) problems

If you forget your PIN code: While the PIN code
entering screen is displayed, press

four times

within 5 seconds. The PIN code you previously stored

will be cleared ( page 45).

with the latest HDMI TV products, due to new standard
adoption.
