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 , t , y , 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
Firm Check information does not match.
NG
( * ：1/2/3/4)
" ▲ " or " ▼ " is displayed as the first
character if the firmware is not correct (see
the illustrations on the right).
An error occurs in Loopback Test of the
DDR memory which is performed during
the initial setting of i/p Scaler (ADV8003).
w
IP SCALER
During the initial setting of i/p Scaler (

TROUBLE SHOOTING
• Check the resistor for
setting the region
: * * . * *
(R1589/R1590 DIGITAL
PCB).
: * * . * *
• Write the firmware for
the correct region.
•Check the circuits
around the IP SCALER
E R R 0 1
(IC401, DIGITAL PCB)
and DDR2 (IC402/IC403).
If there appear to be
E R R 0 2
no problems, IC401 or
IC402/IC403 is faulty.
E R R O R
• Check the firmware
version.
• Check the DIR (IC202,
DIGITAL PCB) and
0 1
surrounding circuits.

IC261/IC271/IC281,
DIGITAL PCB) and
surrounding circuits.
