Chapter 9: Troubleshooting

Remote control problems

Ensure the remote control is set to the correct device mode (- p. 88).

Remove all obstructions between the remote control and the TV.

Replace the remote control’s batteries (- p. 24).

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).

If the TV still does not act as expected, perform the Reset Factory Defaults procedure (- p. 51).

Channel tuning problems

Ensure the remote control is set to the correct device mode (- p. 88).

The Auto Tuning feature may have erased the channel from memory. Add the channel to the channel memory (- p. 30).

The Lock feature may have blocked the channel. Unblock the channel (- p. 45).

If you cannot tune digital channels, check the antenna

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

Closed caption problems

If the program or video you have selected is not closed- captioned, no captions appear.

If text is not available, a black rectangle may appear. If this happens, turn off the closed-caption feature (- p. 42).

A closed-caption signal may not display correctly under the following circumstances: a) the videotape is dubbed; b) the signal reception is weak; or c) the signal reception is nonstandard (- p. 42).

Rating blocking (V-Chip) problems

If you forget your PIN code: While the PIN code entering

screen is displayed, press Q4 times within 5 seconds. The old PIN code is cleared (- p. 43).

The V-Chip feature is available for U.S. V-Chip systems only (- p. 43).

No HDMI® CEC operation

HDMI® CEC Control feature is available for Toshiba HDMI® CEC compatible devices.

Ensure HDMI cables with the HDMI Logo ( ) are used.

When the connected HDMI® CEC device does not work

correctly after you have changed the device’s settings, turn off the TV and unplug the power cord. After 1 minute, plug the power cord in and turn on the TV.

If several devices are connected, HDMI® CEC Control feature may not operate properly.

Read the instruction manual of the connected HDMI® CEC device.

HDMI problems

For HDMI cables

Ensure HDMI cables with the HDMI Logo ( ) are used (- p. 15).

For Legacy HDMI sources

Some legacy HDMI sources may not work properly with the latest HDMI TV products due to new standards. Turn off these HDMI settings (Content Type and INSTAPORT™) (- p. 48).

Network problems

Cannot connect to the Internet

Check the modem and its incoming cable/telephone connections (- p. 23).

Confirm your modem’s operation.

Ensure your IP address is set up correctly.

No network connection

If using a wired network connection, check to ensure the LAN cables are connected properly (- p. 23).

Ensure the modem and router power cords are plugged in and the devices are operating properly.

Ensure your IP address is set up correctly. See Section (- “Setting up the Network”).

Check to ensure proper operation of other network connected devices.

Network Setup fails (Auto)

Check to ensure the LAN cables are connected properly (- p. 23).

DHCP is not enabled on the router, or no router is present. Refer to your router’s documentation for instructions on enabling DHCP. If your router does not support DHCP, you must manually set up the IP address.

Internet service is not available. Check your cable/DSL modem or contact your ISP for Internet service issues.

Network Setup fails (Manual)

Ensure the TV IP address is not the same as any other device on the network.

Example: IP address 192.168.0.100 and IP address 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 Subnet 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.

Reconnect AC power to the television and turn it ON. After 2 minutes, check connection stability.
