Cause/Remedy
• Keep the TV away from electrical noise sources such as cars, motorcycles,
or hair-dryers.
• Make sure that the antenna is connected using the antenna cable (not
supplied).
• Keep the antenna cable away from other connecting cables.
• Do not use a 300-ohm twin lead cable as interference may occur.
• Adjust the antenna direction for the minimum interference. Contact a Sony
dealer for advice.
• Select "Manual Program" in the "Set Up" menu and adjust "Fine" to obtain
better picture reception (page 27).
• Select "NR" (Noise Reduction) in the "Picture" menu to reduce the noise in
the picture (page 19).
• Video head interference. Keep your VCR away from the TV.
• Leave a space of 30 cm between your VCR and the TV to avoid noise.
• Avoid installing your VCR in front of the TV or beside the TV.
• The TV system setting is inappropriate.
If the sound of all the channels are noisy, perform "Auto Program" in the
"Set Up" menu to preset the channels again (page 24).
If the sound of some channels is noisy, select the channel, then perform
"Manual Program" in the "Set Up" menu, and select the appropriate TV
system ("TV System") (page 26).

bright points (pixels) on the screen do not indicate a malfunction.

(page 19).
• The color intensity setting is too low. Select "Color" in the "Picture" menu
to adjust the color intensity (page 19).
