Error Display - Denon AVR-X2500H 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.
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 information does not match.
q
" ▲ " is displayed as the first character if the firmware is not correct (see the illustrations on
Firm Check
the right).
NG
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 Serial Flash (ADV8003),
e
GUI Serial " ▼ " is displayed as the first character of the GUI firmware version.
Flash NG If GUI Serial Flash is damaged, " ▲ " is displayed as the first character.
r
This error is displayed if there is no response from the DIR.
DIR NG
Boot error 1 (After reset the DSP, DSP_Flag0 port is "Low")
Boot Error 2 (After reset the DSP, MCU received state error command)
Signal Detect Error (No response after input set for 1sec)
Mode Change Error (No response after mode change for 1sec)
t
DSP NG
Invalid situation (Detecting invalid situation with autodetect)
Busy Error ("Busy" port remains Low for 1sec)
Output Fs Error (Fs status between MCU output and actual DSP is different)
Input Fs Error (Fs status between AutoDetect Msg and ACCN Msg is different)
SPI communication error
y
Error occurred in BACKUP. it is an error of the check sum.
BACKUP NG
