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 (IC401, DIGITAL PCB) and
DDR2 (IC402/IC403).
If there appear to be no problems,
IC401 or IC402/IC403 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 .

DSP NG
(
#
: 1/2/3/4)
The DSP FLAG0 port does not enter " Hi " status while
booting a DSP code even after resetting DSP.
DSP# ERROR 01
• Check the DSP (IC251/IC261/IC271/
IC281, DIGITAL PCB) and surrounding
circuits.
The DSP FLAG0 port does not enter " Hi " status before
issuing a DSP command.
DSP# ERROR 02
Setting WRITE to " Lo " does not set ACK to " Hi " during
DSP data reading.
DSP# ERROR 03
Setting REQ to " Lo " does not set ACK to " Lo " during
DSP data reading.
DSP# ERROR 04
Setting WRITE to " Hi " does not set ACK to " Hi " during
DSP data writing.
