t Make sure the TV is set to the video channel. If you are using a
monitor, set it to video input.
t If the VCR is connected to the TV with a Scart cable, make sure the
TV/VIDEO indicator is lit in the display window. Use the TV/VIDEO
key on the remote commander to light the TV/VIDEO indicator.
t If your VCR is connected to the TV with only an aerial cable, make
sure the TV is correctly tuned to the VCR (see page 18).
t If your TV is connected to the VCR with both a Scart and an aerial
cable, make sure the RF channel is set to OFF (see page 18).

cable, make sure the RF channel is set to OFF (see page 18).
t Existing broadcasts may interfere with the VCR. Reset the RF
channel output of your VCR (see page 18).

t The video heads are dirty (see below). Clean the video heads using
the Sony T-25CLD, E-25CLDR, or T-25CLW video head cleaning
cassette. If these cleaning cassettes are not available in your area,
have the heads cleaned at your nearest Sony service facility (a
standard service charge will be required). Do not use a commercially
available liquid type cleaning cassette other than Sony's, as it may
damage the video heads.

service facility for more information.
