Troubleshooting guide

≥Insert the AC power supply cord securely into the household AC outlet.
≥The unit is hot ("U14" appears on the display).
Wait for "U14" to disappear.
≥One of the unit's safety devices may have activated.
Reset the unit as follows:
(1) Press [Í/I] (1) on the main unit to switch the unit to standby.
If the unit doesn't switch to standby, press and hold [Í/I] (1) for about 10 seconds. The
unit is forcibly switched to standby.
Alternatively, disconnect the AC power supply cord, wait one minute, then reconnect it.
(2) Press [Í/I] (1) to turn the unit on.
≥One of the unit's safety devices may have activated.
Press [Í/I] to turn the unit on.
≥Make sure the television's input setting (e.g., AV1) is correct. (pages 10 and 11)
≥You have set "Progressive (NTSC)" to "On" in the Connection menu, but the television is not
compatible with progressive signals. Press [∫] (7) and [TIME SLIP] (25) on the unit at the same
time for about 5 seconds. The setting will change to interlace.
≥This can occur because the signals are being divided between the unit and the television.
It can be solved by using a signal booster, available from audio-visual suppliers.
Consult your dealer if reception does not improve.
≥Check the settings on your television.
≥Check the settings for "TV Aspect", "Norm (4:3) TV Settings (DVD-Video)" or "Norm (4:3) TV
Settings (DVD-RAM)" in the Connection menu. (pages 12 and 53)
≥Adjust the television's vertical hold. Read the television's operating instructions or consult your
dealer.

Press [STATUS] (28) to show the on-screen messages constantly.
≥Go to Display in the SETUP menus and select "On" for "Grey Background". (page 53)
≥Set "Progressive" to "OFF". This problem is caused by editing method or material used on
DVD-Video, but should be corrected if you use interlace out put. (page 44)
≥The effect is less perceivable with some types of video.
≥Check the connections. (pages 10 and 11)
≥Check the input mode on the amplifier if you have connected one. (pages 46, 47 and 54)
≥Turn V.S.S. to "OFF" if it causes distortion. (page 44)

[DVD-R]

connection). (pages 10, 11 and 47)
