Firm Check
NG
The model name, brand name and region information written in the rmware are compared
to the region settings in the PCB. This error is displayed if the information does not match.
" ▲ " is displayed as the rst character if the rmware is not correct (see the illustrations on
the right).

PIMG :********
• Check the resistor for setting the region [R1524, 1525, DIGI-
TAL PCB].
• Write the rmware for the correct region.
PIMG Error indication
• 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 .

GUI Serial
Flash NG
If the Main CPU version is not supported by the GUI Serial Flash (ADV8003),
" ▼ " is displayed as the rst character of the GUI rmware version.
If GUI Serial Flash is damaged, " ▲ " is displayed as the rst character.
