Before requesting service, use this chart and see if you can repair the trouble yourself. Small problems are often easily 
corrected, and this can save you the trouble of sending your VCR off for repair.

1. The power will not come on.

• The AC power cord is 

disconnected.

Connect the AC power cord.

2. The clock works, but the VCR’s 

power will not come on.

• The VCR is in the timer recording 

standby mode with “AUTO TIMER” 
set to “OFF” (A page 68).

Press [TIMER (j)] to disengage.

3. The Remote will not function.

• The batteries are weak.

Replace the dead batteries with new ones.

1. The cassette gets stuck partway 

during loading, and is ejected.

• The cassette was inserted 

incorrectly.

Make sure the cassette’s window is 
facing up, the rear label side is facing 
you and the arrow on the front of the 
cassette is pointing towards the VCR. 
Then insert the cassette.

1. The tape is running but the pic-

ture will not appear.

• The TV receiver is set to the wrong 

mode.

If you are using the AV, HDMI, DVI, 
Component Video or S-Video 
connection, set the TV to its AV mode.

2. Breaks are noticeable in Hi-Fi 

sound track.

• Automatic tracking is engaged.

Disengage auto tracking and adjust 
the tracking manually (A page 30).

3. The playback picture is blurred or 

interrupted, even though TV 
broadcasts are clear.

The heads must be cleaned. Use an 
optional dry cleaning cassette, or 
consult your JVC dealer.

mosaic noise appears when play-
ing back a program recorded in 
D-VHS mode.

• The video heads may be dirty.

in D-VHS mode.

The heads must be cleaned. Use an 
optional dry cleaning cassette, or 
consult your JVC dealer.
To record in the D-VHS mode, use a 
D-VHS cassette.

mode, press [D-VHS] so that the [D-
VHS] indicator lights up, then 
perform the recording (A page 35).

7. The mosaic noise appears when 

receiving the scenes with fast 
action or switching the display.

• This occurs when receiving the 

program with the low transfer rate.

This noise already appears in the 
broadcast station, and this is not a 
malfunction of your VCR.

8. Images cannot be displayed on 

the TV. And the [

q

] indicator on 

the front display panel lights up.

pressed, power off this VCR, press 
and hold [PAUSE (W)] on the front
