TV.

• Your TV’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 your TV

remote control does not operate a specific feature on another

device, use the remote control that came with the device

(- p. 91–96).

Factory Defaults procedure (- p. 51).

(- p. 88).

memory. Add the channel to the channel memory (- p. 30).

channel (- p. 45).

• If you cannot tune digital channels, check the antenna

configuration (- p. 30). If the problem persists, clear all

channels fr

om the channel list and reprogram channels into

memory (- p. 30). If the problem persists, use the Reset

Factory Defaults procedure (- p. 51). See “TV stops

responding to controls” and “Other problems” (- p. 77).

captioned, no captions appear.

modem or contact your ISP for Internet service issues.

on the network.

192.168.0.101 are different addresses on the same network.

• Make sure the TV IP address is on the same subnet as the

networked PC.

Example of proper setup: The PC has the IP address

192.168.0.100 with the Sub

net mask 255.255.255.0, the TV

has the IP address 192.168.0.101 with the Subnet mask

255.255.255.0; both are on the same subnet.

Example of improper setup: The PC has the IP address

192.168.1.100 with the Subnet mask 255.255.255.0, the TV

has the IP address 192.168.0.101 with the Subnet mask

255.255.253.0; they are on different sub-nets.

Unstable network connection

• When using a wired home-network connection, unplug the

LAN cables, and then reconnect them.

• When using a wireless home-network connection:

– Remove AC power from the router and the television for

1 minute.

• Reconnect AC power to the router.
