Troubleshooting
Additional Information
If you have any questions or problems not covered below, please consult your
nearest Sony service facility.
Remedy
• Connect the mains lead to the mains securely.
• Moisture condensation has occured. Turn the power
off, unplug the mains lead and leave the VCR to dry
for over four hours.
• The clock stops if the VCR is disconnected from the
mains for more than eight hours. Reset the clock (and
timer).
• Make sure the TV is set to the video channel. If you are
using a monitor, set it to video input.
• If you made connections using the aerial cable only,
make sure the RF channel number is set correctly for
your area.
• Adjust the tracking with the TRACKING +/– buttons.
• Make sure the colour system is correctly set to the
system that the tape was recorded in.
• The video heads are dirty (see page 67). Clean the
video heads using the Sony T-25CLD, T-25CLW or
E-25CLDR 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 they may damage the video
heads.
• If a message appears, this indicates that the Head
Condition Sensor has detected dirty video heads.
Follow the on-screen message. For details about the
Head Condition Sensor, see page 68.
• The video heads may have to be replaced. Consult
your local Sony service facility for more information.
• Adjust the vertical hold control on the TV or monitor.
• The tape is defective.
• If you made A/V connections, check the audio cable
connection.
• When you play a tape with the same sound recorded
on both the hi-fi and normal sound tracks, make sure
the AUDIO MIX option in the SET UP MENU is set to
OFF.
