TROUBLE SHOOTING
*
• Check the resistor for setting
region(R1580/R1581, DIGITAL
*
PCB).
• Write the firmware for the
correct region.
*
*
*
• Check the SUB(IC171) and
surrounding circuits.
• Check the circuits around the
IP SCALER (IC401, DIGITAL
PCB) and DDR2 (IC402/
IC403).
If there appear to be no prob-
lems, IC401 or IC402/IC403 is
faulty.
R .
• Check the firmware version.
• Check the DIR (IC201, DIGI-
TAL PCB) and surrounding
circuits.
• Check the DSP (IC251, DIGI-
TAL PCB) and surrounding
circuits.
