Many of the electric and structural parts used in the set
have special safety properties. In most cases these
properties are difficult to distinguish by sight, and using
replacement parts with higher ratings (rated power and
withstand voltage) does not necessarily guarantee that
safety performance will be poreserved. Parts with safety
properties are indicated as shown below on the wiring
diagrams and parts lists is this service manual. Be sure to
replace them with parts with the designated part number.

WIRE ARRANGEMENT
If wire bundles are untied or moved to perform adjustment or parts replacement etc., be sure to rearrange them neatly as they
were originally bundled or placed afterward.
Otherwise, incorrect arrangement can be a cause of noise generation.

1.2. Check for Update and Update
Check if the latest firmware exists. You can also check approximately how long it will take to complete an update.
(1) Press the SETUP button on the remote control to display the GUI menu.
(2) Use the cursor buttons to select "Other settings" → "Firmware update" → "Update check".
(3) Press the ENTER buttom.
• The latest version of the firmware uploaded to the web is displayed.
• If the latest firmware version is on the web, proceed to (4).
• If the latest firmware is already installed, press the SETUP button to close the menu.
(4) Use the cursor buttons to select "Update", then press the ENTER button.
• During update, the power indicator lights red and the GUI screenis shut down. And a rough remaining time is
indicated on the display.
• When updating is complete the power indicator lights green and normal
• status is resumed.
(5) Press the SETUP button to close the menu.
--- Cautions on Firmware Update ---
• In order to use these functions, you must have the correct system requirements and settings for a broadband Internet
connection.
• Do not turn off the power until updating is completed.
Even with a broadband connection to the Internet, approximately about 1 hour is required for the updating procedure to be
completed.
Once updating starts, normal operations on the DVD-A1UD cannot be performed until updating is completed. Also, setting items of the GUI menu of DVD-A1UD or setting items of the image adjustment may be initialized.
Make a note of the settings before updating, and set them again after updating.
