Chapter 7: Troubleshooting - Mitsubishi Electric WD-52628 Owner's Manual

IEEE 139 Devices
Symptom
1. Excessive digital artifacts when viewing an IEEE
1394 device.
2. D-VHS recordings for digital cable have drop-
outs (loss of picture or sound), or no playback.
3. There is no audio and video from the IEEE 1394
device.
4. The IEEE 1394 Device is not listed in the Device
Selection menu.
5. The IEEE 1394 device cannot be selected (is
grayed out).
6. DEVICE MENU button does not display a menu.
7. All IEEE 1394 devices disappear.
8. Cannot rediscover a deleted IEEE 1394 device.
9. An IEEE 1394 device has been plugged in but
does not appear in the Device Selection menu
(not discovered).

Chapter 7. Troubleshooting
Suggested Solution
• The IEEE 1394 cable is too long; 15 feet between devices is the maximum.
• There may be a slow device in the middle of the IEEE 1394 network. Move the
slow devices to the end so that connections for faster devices do not pass
through them.
Digital cable signals on IEEE 1394 can exceed the data rate standards
supported by DVCR.
• The device is not turned on. Turn the device power on.
• No media (tape or disc) is inserted into the device.
• The media is blank (has no recording).
• The play command failed - Try pressing play again on the device's remote control
or front panel.
• The device is already in use (for example, the device is currently recording).
• The source is copy-protected or violates copy protection.
• The device's digital video signal is not supported by the TV, as may be the case
with an IEEE 1394 signal from a computer. Use analog connections instead, if
available.
• The device is not an audio/video device.
• Too many other devices are already communicating over IEEE 1394. Remove or
stop some devices and try again.
• The device is unchecked in the Review screen. Select the NetCommand menu.
Through Review, verify the device is checked.
• The IEEE 1394 plug is disconnected or loose.
• The IEEE 1394 Device has not been powered On. Turn on.
• The device has not been discovered.
• The device is not an Audio/Video device
The device may be busy, either recording or a peer-to-peer connection
has been established. Cancel the recording or peer-to-peer connection.
• The IEEE 1394 device does not provide a menu.
• The TV cannot support IEEE 1394 menus.
• The connected devices must not be in a loop that returns to the TV. Make sure a
device is connected at the end.
• Disconnect all the cables and devices from the TV. Replace them one by one to
locate the problem device or cable
• Use System Reset (front control panel).
• The device has been disconnected. Plug it in.
• The device is unchecked in the Review screen. Select NetCommand from the
Main menu, then select Review. Check the device.
• Remove IEEE 1394 plug. Go to the Edit NetCommand menu. Delete the IEEE
1394 device. Plug the device in again so it can be discovered again.
• The IEEE 1394 connection to the TV or another device is not secure or is loose.
• The IEEE 1394 device is not powered on.
• A device in the IEEE 1394 chain is not powered on. Turn on all the devices.
• The device discovery can take as long as a minute to initiate.
• IEEE 1394 cable is too long (maximum of 15 feet between devices).
• The IEEE 1394 device uses an incompatible protocol and will not be discovered
