The model name, brand name and region information written in the rmware are compared
to the region settings in the PCB. This error is displayed if the information does not match.
" ▲ " is displayed as the rst character if the rmware is not correct (see the illustrations on
the right).

• Check the resistor for setting the region [R7581, R7582, DIGI-
TAL PCB].
• Write the rmware for the correct region.
PIMG Error indication
• Check the circuits around the Logic [IC722] and SFROM
[IC723]. If there appear to be no problems, [IC722] or [IC723]
is faulty.
w
DIR NG
This error is displayed if there is no response from the DIR.

• Check the DIR [IC761, DIGITAL PCB] and surrounding circuits.
e
DSP NG
Boot error 1 (After reset the DSP, DSP_Flag0 port is "Low")
DSP ERROR 01
• Check the DSP [IC781, DIGITAL PCB] and surrounding cir-
cuits.
