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.
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 informa-
q
tion does not match.
Firm Check
NG
" ▲ " or " ▼ " is displayed as the first char-
acter 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 NG
During the initial setting of i/p Scaler
(ADV8003), there is not the reply of the
Loopback Test result of the DDR memory.
e
If the Main CPU version is not supported
GUI Serial
by the GUI Serial Flash (ADV8003),
Flash NG
This error is displayed if there is no re-
r
DIR NG sponse from the DIR.
The DSP FLAG0 port does not enter "Hi"
status while booting a DSP code even
after resetting DSP.
The DSP FLAG0 port does not enter "Hi"
status before issuing a DSP command.
Setting WRITE to "Lo" does not set ACK to
t
"Hi" during DSP data reading.
DSP NG
Setting REQ to "Lo" does not set ACK to
"Lo" during DSP data reading.
Setting WRITE to "Hi" does not set ACK to
"Hi" during DSP data writing.
Setting REQ to "Lo" does not set ACK to
"Lo" during DSP data writing.
An error occurred in a checksum of the

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
(IC104, DIGITAL PCB)
and DDR2 (IC402/IC403).
• If there appear to be
E R R 0 2
no problems, IC104 or
IC402/IC403 is faulty.
• Check the firmware
E R R O R
version.
• Check the DIR (IC202,
DIGITAL PCB) and sur-
0 1
rounding circuits.

0 2
• Check the DSP (IC251,
0 3
DIGITAL PCB) and sur-
rounding circuits.
