TROUBLE SHOOTING
• Check the resistor
for setting the re-
gion(R1524 / 1525
HDMI PCB).
• Write the firmware for
the correct region.
• Check the circuits
around the IP SCALER
0 1
(U1026, HDMI PCB) and
DDR2 (U1028/1029).
If there appear to be
0 2
no problems, U1026 or
U1028/1029 is faulty.
• Check the firmware
version.
• Check the DIR (U1040,
HDMI PCB) and sur-
0 1
rounding circuits.
0 1
0 2
• Check the DSP (U1073,
0 3
HDMI PCB) and sur-
rounding circuits.
