PDP-503CMX, PDP-503MXE, PDA-5002
When a module microcomputer failed in communication with a panel
microcomputer, this NG occurs.
Shut down after OSD display for 30 seconds from the NG detection.
Abnormality to expect
Open / Short of communication line in the Assy
1
Panel microcomputer NG
When a module microcomputer failed in communication with outside
EEPROM or EXPANDER, this NG occurs.
Shut down after OSD display for 30 seconds from the NG detection.
* However, this communication NG may occur in the standby state.
Abnormality to expect
• Open / Short of communication line in the Assy
• Breaking of wire between DIGITAL VIDEO Assy (D1) and SW POWER
SUPPLY Module (P2).
2
DIGITAL-IIC communication NG
When it becomes the dew drop state in this unit, this NG occurs.
After the dew drop detection, shut down immediately.
Abnormality to expect for dew drop
Disconnect a connector CN2002 between Dew drop sensor and Y DRIVE Assy.
3
Dew drop detection
When temperature of this unit became abnormally high, this NG occurs.
Shut down after OSD display from the NG detection for 30 seconds.
Abnormality to expect when it occurs in the environment that is not
high-temperature
• Disconnect a connector between SP TERMINA (L) Assy (SPL1) and
MX AUDIO Assy (A3).
• Disconnect a connector between MX AUDIO Assy (A5) and RGB Assy (R8).
• Disconnect a connector between DIGITAL VIDEO Assy (D18) and
temperature sensor 1 (TE1).
Shut down temperature of each temperature sensor
TEMP2 data 150 ( 80

* TEMP1 is not shut down by temperature, and it shuts down when
connector was disconnected.
