etc., is turned on.

OUT OF FRQUENCY

An input signal is not received normally.

no picture .

• Check the contrast and brightness settings (adjust them for higher

contrast and brightness).

• Check the way the signal cable is connected.

slantwise.

vertically streaked, with the characters in
vertical columns blurred.

blurred.

(RGB input)

• The remote controller does not work.

• Check to see if the batteries are loaded in the remote controller in

opposite direction.

• Check to see if the batteries in the remote controller are OK.

• The screen becomes dark and the images

cannot be seen during VTR special
playback (fast forward, rewind).

• This sometimes occurs when a component output VTR such as

the 480i is connected.

This is not a malfunction; therefore, please take note that this may
occur. When it does occur, change to composite output, or S1 (or
S2) output.

• The display image does not come out by the SCART signal.

• Check the way the signal cable is connected.
• Check the setup.
• The S video terminal has priority and when used in composite, the

picture can become dark, as there is no synchronizing signal. In
this case, remove the S terminal cable.
