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 [U2800, DIGITAL PCB] and
DDR2 [U3000/U3001].
If there appear to be no problems,
[U2800] or [U3000/U3001] 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 .
