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 .
