Troubleshooting
Symptom Remedy
Power The POWER switch does not
function. • Connect the AC power cord securely.
The power is turned on but the
VCR does not operate. Moisture condensation occurs. Turn the power off, unplug the AC
power cord and leave the VCR to dry for over an hour.
Clock The clock has stopped and
lights in the display window. The clock stops if the VCR is disconnected from the wall outlet for
more than three hours. Reset the clock (and timer).
Playback The playback picture does not
appear on the TV screen. Make sure the TV is set to the channel for the VCR. If you are using a
monitor, set it to video input.
The picture is not clear. Adjust the tracking with the TRACKING NORMAL/SLOW buttons.
The video heads are dirty (see below). Clean the video heads using the
Sony T-25CL video head cleaning cassette. If this cleaning cassette is
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 wet-type cleaning cassette, as it may damage
the video heads.
The video heads may have to be replaced. Consult your local Sony
dealer for more information.
The picture rolls vertically during
picture search. Adjust the vertical hold control on the TV or monitor.
The picture has no sound. The tape is defective. Use a new tape. •
Both main and SAP sounds are
heard. • When you play a bilingual tape, make sure the AUDIO MIX option in
the ADVANCED OPTIONS is set to OFF.
