1.4. Error display
See the table below for descriptions of the displayed errors and countermeasures for these.
If multiple errors occur, only one item is displayed.
The priority order is w , e , r , y , u , q .
Condition
The model name, brand name and region
information written in the firmware
are compared to the region settings in
the PCB. This error is displayed if the
q
information does not match.
Firm Check
NG
" ▲ " is displayed as the first character
if the firmware is not correct (see the
illustrations on the right).
w
Sub μ -COM There is not a reply from SUBμ-COM.
NG
An error occurs in Loopback Test of the
DDR memory which is performed during
the initial setting of i/p Scaler (ADV8003).
e
IP SCALER NG
During the initial setting of i/p Scaler (
ADV8003 ) , there is not the reply of the
Loopback Test result of the DDR memory .
If the Main CPU version is not supported
r
by the GUI Serial Flash (ADV8003),
GUI Serial
" ▼ " is displayed as the first character of
Flash NG
the GUI firmware version.
This error is displayed if there is no
t
DIR NG response from the DIR.

• Write the firmware for
the correct region.
• Check the SUB(U2101)
0 1
and surrounding circuits.
• Check the circuits
around the IP SCALER
E R R 0 1
(U2800, DIGITAL PCB)
and DDR2 (U3000/
U3001).
If there appear to be
E R R 0 2
no problems, U2800 or
U3000/U3001 is faulty.
