Try This...
• Check that the programmed recording light lights up in the front panel
display.
• Check the clock time.
• Make sure you have turned the VCR off before the start time.
• Check the tracking control. Adjust manually if necessary.
• Check the monitor settings.
• Check the quality of the video tape.
• Try automatic head cleaning.
• Clean the video heads using a dry-type video head cleaning cassette.
Do not use a wet-type cleaning cassette, as it may damage your
VCR. Excessive use of a cleaning cassette could shorten head life.
Follow the cleaning instructions carefully.
• Have the VCR video heads cleaned by a qualified service technician.
• Check that VCR operational setting is set to VCR-A.
• Check to see that the VCR/TV slide switch is set to the correct
position.
• Change the batteries.
• In order to protect your tapes and the VCR heads, the Fast
Forwarding/Rewinding Speed will be slower than 500x under the
following conditions:
1 Use of tapes shorter in length than T-120 (for example, T-30, T-60,
T-90).
2 Activating fast forwarding or rewinding from the middle of the tape.
