Firm Check
NG
The model name, brand name and region
information written in the firmware are
compared to the region settings in the
PCB.This error is displayed if the informa-
tion does not match.
" ▲ " is displayed as the first character
if the firmware is not correct (see right
section of table).

• Write the firmware for
the correct region.

• Check the SUB(IC171)
and surrounding cir-
cuits.

IP SCALER NG
An error occurs in Loopback Test of the
DDR memory to perform at 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
(IC401, HDMI PCB) and
DDR2 (IC402/IC403).
If there appear to be
no problems, IC401 or
IC402/IC403 is faulty.
In initial setting of i/p Scaler ( ADV8003 ),
there is not the reply of the Loopback Test
result of the DDR memory .
