TV will not turn on

• Make sure the power cord is plugged in, and then press POWER.

• The remote control batteries may be dead. Replace the batteries or try the front panel buttons.

• Press the RESET button on the TV front panel (page 9).

Picture problems

• Check the antenna/cable connections (pages 12–17).

• Press INPUT on the remote control or TV/VIDEO on the TV front panel and select a valid video input

source (page 61). If no device is connected to any of the inputs 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.

• Make sure you have not connected more than one device to the same VIDEO input on the TV (page 10).

• Adjust the picture qualities in the VIDEO menu (pages 72–74).

• If you are using a VCR, make sure the TV/VCR button on the remote control is set correctly (page 26).

• If you have two VCRs connected to your TV, do not connect the same VCR to the TV’s output and input

connections at the same time (page 17).

• Do not connect a standard video cable and an S-video cable to VIDEO-1 or VIDEO-2 on the TV back (or

VIDEO-3 on the TV front) at the same time (page 10).

Noisy picture

feature to ON to reduce visible interference in the TV picture (page 74).

TouchFocus button on the TV front panel to automatically adjust the color convergence, or manually
adjust the color convergence (page 50).

the ColorStream connections (page 16).
