70 EN TROUBLESHOOTING 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. POWER SYMPTOM 1. The power will not come on. 2. The clock works, but the VCR's power will not come on. 3. The Remote will not function. TAPE TRANSPORT POSSIBLE CAUSE ● The AC power cord is disconnected. ● The VCR is in the timer recording standby mode with "AUTO TIMER" set to "OFF" (੬ pg. 56). ● The child lock function is activated. ● The batteries are discharged. CORRECTIVE ACTION Connect the AC power cord. Press TIMER to disengage. Press and hold POWER on the Remote for more than seven seconds to release the child lock function (੬␣ pg. 78). Replace the dead batteries with new ones. SYMPTOM 1. The cassette gets stuck partway during loading, and is ejected. POSSIBLE CAUSE ● The cassette was inserted incorrectly. CORRECTIVE ACTION 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. PLAYBACK SYMPTOM 1. The tape is running but the picture will not appear. 2. Breaks are noticeable in Hi-Fi sound track. 3. The playback picture is blurred or interrupted, even though TV broadcasts are clear. 4. The Hi-Fi sound cannot be heard. POSSIBLE CAUSE ● The TV receiver is set to the wrong mode. ● Automatic tracking is engaged. ● The video heads may be dirty. ● Audio Monitor setting is incorrect. CORRECTIVE ACTION Select the AV mode on the TV. Disengage auto tracking and adjust the tracking manually (੬ pg. 23). The heads must be cleaned. Consult your JVC dealer. Set Audio Monitor to "HI-FI" (੬ pg. 23). RECORDING SYMPTOM 1. Recording will not start. POSSIBLE CAUSE ● There is no cassette loaded. ● The loaded cassette has had its record safety tab removed. 2. TV broadcasts will not be recorded properly. 3. Tape-to-tape editing will not work. ● The VCR has been set to "L-1", "L-2", "F-1" or "I-1 etc." input mode by mistake. ● The components have been incorrectly connected, or correct video connector (S VIDEO, VIDEO or DV) is not selected. ● The power to one or more of the units has not been turned on. ● The recording VCR's input mode has been set incorrectly. CORRECTIVE ACTION Insert a cassette. Remove the cassette and cover the hole with adhesive tape, or load a cassette on which the record safety tab is intact. Select the appropriate channel on the VCR. Connect the components correctly (੬ pg. 62, 64) or check "REAR AUX L-1 (or L-2)" and "FRONT AUX F-1" setting (੬ pg. 55). Make sure the power to all units is on. Select the appropriate input mode on the recording VCR.
