TROUBLE SHOOTING
• Check the resistor for setting the
region(R1524 / 1525 DIGITAL PCB).
• Write the firmware for the correct
region.
• Check the circuits around the IP
SCALER (U1026, DIGITAL PCB) and
DDR2 (U1028/1029).
If there appear to be no problems,
U1026 or U1028/1029 is faulty.
• Check the firmware version.
