PANASONIC - TC-26LX20_TC-32LX20_TC-22LR20_ SERVICE MODE _ SELF CHECK MODE



SELF CHECK

     The self-check feature is designed to check if a particular component is functioning and it does not actually diagnose the problem .For example “Tuner Check OK” doesn’t’ necessarily mean that it is OK. It pings or selectively addresses that particular device via the I2 Bus to determine if it exists. The same holds true for the Global Core IC’s, the MTS, the Sound circuit, and the Audio/Video switches. However, it should be noted that the displayed results could be misleading by indicating that it is OK.

     
     To access the self check mode: Press the VOLUME-Down Button on the unit and SLEEP button on the remote at the same time. To exit press any key.

SERVICE ADJUSTMENT MODE

While the unit is powered on, hold down the “Volume Down” button on the unit while pressing the “Display” button on the remote three times (within 2 seconds).

Service mode is broken down into two categories, Main Items, which are all displayed on the menu screen and Sub Items.

  • Use the number buttons “1” and “2” on the remote control to change the Main Item. The number “1” button will cycle from the MAIN option down to the DVD option. The number “2” button will cycle in reverse direction.
  • Use the number buttons “3” and “4” on the remote control to cycle through the Sub Items until the proper adjustment is reached.
  • Adjustment of the Sub Item is made using the “Volume” buttons on the remote control.
  • Data changes are saved automatically when you switch Sub or Main Items, or if you exit the service mode.

When the DVD adjustments are accessed, the unit switches to the DVD mode. The software version of the DVD Player can be displayed here.

TO EXIT SERVICE MENU MODE

  • Switch off the “Power” button on the main unit or press the “Power” button on the remote control.
