NG
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 information does not match.
" ▲ " is displayed as the first character if the firmware is not correct (see the illustrations on
the right).

• Check the resistor for setting the region [R1524, 1525, DIGI-
TAL PCB].
• Write the firmware for the correct region.
• Check the circuits around the Logic[U1053] and
SFROM[U1048]. If there appear to be no problems, [U1053]
or [U1048] is faulty.

IP SCALER NG
An error occurs in Loop back Test of the DDR memory which is performed during the initial
setting of i/p Scaler(ADV8003).
IP SCALER ERR 01
• Check the circuits around the IP SCALER [U1026, DIGITAL
PCB] and DDR2 [U1028/U1029].
If there appear to be no problems, [U1026] or [U1028/U1029]
is faulty.
During the initial setting of i/p Scaler ( ADV8003 ) , there is not the reply of the Loop back Test
result of the DDR memory .
