Error Display - Denon AVR-X2300W Service Manual

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 States
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 infor-
q
mation does not match.
Firm Check
NG
" ▲ " is displayed as the first character if the firmware
is not correct (see the illustrations on the right).
s
An error occurs in Loop back 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 Loop back Test result of
the DDR memory .
If the Main CPU version is not supported by the GUI

TROUBLE SHOOTING
• Check the resistor for setting the
region(R1524 / 1525 HDMI PCB).
• Write the firmware for the correct
region.
• Check the circuits around the IP
SCALER (U1026, HDMI PCB) and
DDR2 (U1028/1029).
If there appear to be no problems,
U1026 or U1028/1029 is faulty.
• Check the firmware version.
• Check the DIR (U1040, HDMI PCB)
and surrounding circuits.
• Check the DSP (U1073, HDMI PCB)
and surrounding circuits.
