The temperature at the PANEL SENSOR ASSY of the PDP-505PE/PRO-505PU is indicated as the TEMP 1 value (000-255), which should be converted using the following formula: 0.65 × TEMP 1 value - 52 Current temperature (°C) Note: Shutdown caused by high TEMP 1 value PDP-505PE: TEMP 1 value >...

  • Page 67: Operation When The Media Receiver Is Not Connected

    7.1.4 OPERATION WHEN THE MEDIA RECEIVER IS NOT CONNECTED As the connection conditions of the system cables (MDR cable, DVI cable) are usually detected, if no connection, such as cable disconnection, is detected, a warning indication (alternate flashing of the red and green areas) is displayed on the mask screen, and the red and green LEDs flash alternately.

  • Page 68: Power On/Off Function For The Large-Signal System

    7.1.6 POWER ON/OFF FUNCTION FOR THE LARGE-SIGNAL SYSTEM Function: Only the power for the low voltage lines (16.5 V, 12 V, and 6.5 V) is on, and the power for the high voltage lines (VSUS, VADR) is off. Usage: 1. Use when only an operational check for the low voltage lines is required, such as when making repairs. 2.

  • Page 69: Backup When The Main Unit Is Adjusted

    7.1.7 BACKUP WHEN THE MAIN UNIT IS ADJUSTED Outline The data on the adjustment values for the main unit are stored in an EEPROM (IC5206, 4 kbits) on the DIGITAL VIDEO Assy. Part of the data (area A in the figure below) are automatically copied to an EEPROM (IC4002, 2 kbits) mounted on the PANEL IF Assy for backup.
  • Page 70 3. When a repaired DIGITAL VIDEO Assy is mounted on the original unit (reuse of the repaired DIGITAL VIDEO Assy) Changing of keywords is not required. After the repaired DIGITAL VIDEO Assy is mounted in the original unit, the unit can operate with its latest adjustment values.
  • Page 71 [Clearing the data in the ROM of the DIGITAL VIDEO Assy] After either YES or NO is selected on the display shown above, the indication shown below is automatically displayed. Move the cursor to YES then press the Enter key. The data in the ROM of the DIGITAL VIDEO Assy become those for a service part (not adjusted). Notes: •...
