PDP-503PE, PDP-503PU
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 DIGITAL VIDEO, MR INTERFACE
and AUDIO Assys
• Breaking of wire of the following points is thought about.
DIGITAL VIDEO Assy (D1) ↔ SW POWER SUPPLY Module (P2)
DIGITAL VIDEO Assy (D3) ↔ MR INTERFACE Assy (R3)
MR INTERFACE Assy (R23) ↔ AUDIO Assy (A24)
System Cable
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.
Note: When temperature fell down during indication, return to the normal operation.
Abnormality to expect when it occurs in the environment that is not
high-temperature
• Disconnect a connector between DIGITAL VIDEO Assy (D18) and
temperature sensor 1 (TE1).
Shut down temperature of each temperature sensor
