DDR memory which is performed during
the initial setting of i/p Scaler (ADV8003).
I P S C A L E R E R R 0 1
• Check the circuits
around the IP SCALER
(IC104, DIGITAL PCB)
and DDR2 (IC402/IC403).
• If there appear to be
no problems, IC104 or
IC402/IC403 is faulty.
During the initial setting of i/p Scaler
(ADV8003), there is not the reply of the
