TV: Pioneer KRL-32V / KRL-37V Service Mode


Activating public mode

  • Make sure the TV is switched off (not in standby)
  • While keeping the 'VOL+' and 'INPUT' buttons on top of the TV pressed, switch on the power, until 'Public Mode' and '---' appears.
  • Enter the 3-digit entry code: 027 (thanks to P. Palmiris)

Public Mode
POWER ON FIXED [VARIABLE / FIXED_ALL / FIXED_BODYKEY / RC RESPOND] In "Fixed" setting, the power-off by the power key of the unit is invalidated and the image is kept being received. The power can be turned off by disconnecting the power supply.
SHUT DOWN MODE [NORMAL / QUICK]
MAXIMUM VOLUME [0 - 60 (60)] Sound volume can not be adjusted higher than the preset value. When the sound volume is set lower than 59, only figures are displayed and the sound volume bar is not displayed. The maximum sound volume for ON-timer (Wake up timer) is limited also to the preset value. When the sound volume is set higher than the MAX setting by the adjusting process, the sound volume control operation is prohibited for turn-up and the sound volume should be turned down to MAX in this state.
VOLUME FIXED [VARIABLE / FIXED / AC CTRL / AC/RC CTRL] FIXED: Fixed at the level adjusted for a fixed volume.
AC CTRL: Start-up at the level specified for a fixed volume at ACON.
AC/RC CTRL: Start-up at the level specified for a fixed volume at start.
The sound volume for the ON-timer (Wake up timer) is fixed also without display of menu. Besides, the setting is made impossible. (Basically, the menu is not displayed.) The following keys become invalid: Sound volume Up/Down (VOL +/-) [for both remote control and the unit] Mute (MUTE) In the item "VOLUME" of adjustment process, the sound volume can be set freely irrespective of this setting. As for sound volume fixing and sound volume MAX level, the sound volume fixing has priority. Once the sound volume has been changed by adjustment process, it should be set back to the sound volume preset by sound volume fixing level when the adjustment process ends.
VOLUME FIXED LEVEL [0 - 60 (20)] The sound volume to be fixed by "Volume fixed" is determined. Setting is valid only when "Volume fixed" is selected for "fixed".
RC BUTTON [RESPOND / NO RESPOND / LIMITED] Making the remote controller settings.
At the "No Respond" setting, the remote controller keys are disabled. Its power key (reception/standby key) is disabled too.
At the "Limited" setting, some channel-related keys alone are operative. All the other remote controller keys (power, volume up/down , channel up/down, light control (brightness sensor), broadcast select) are inoperative.
At "No respond" setting, all the keys (including the power key) are not accepted. Adjustment process, inspection process and hotel only keys are valid irrespective of setting.
PANEL BUTTON [RESPOND / NO RESPOND] All the operations by keys (except the power key) of the unit can be invalidated.
Adjustment process, inspection mode and hotel menu mode can be started irrespective of setting. All the keys can be used in adjustment process, inspection mode and hotel menu irrespective of setting.
MENU BUTTON [RESPOND / NO RESPOND] In "No respond" setting, the menu operation by the menu key of the remote control and the menu key of the unit are invalidated.
Adjustment process, inspection mode and hotel menu mode can be started irrespective of setting. All the keys can be used in adjustment process, inspection mode and hotel menu irrespective of setting.
AV POSITION FIXED [VARIABLE / FIXED] In case of "Fixed" setting, Menu "Picture" and "Audio" setting can't be changed like "Dynamic (Fixed)". When "AV Mode" key is pressed, TV just displays current AV Mode (cannot be changed).
When receiving with AV Position key, OPC, Dolby key and other direct audio select keys, the current display stays on and no setting can be changed. Even by initializing personal information, the hotel-mode settings are kept intact. In this way, the AV positions, video and audio adjustment settings are not initialized.
ON SCREEN DISPLAY [YES / NO / LIMITED] At the "No" setting, the following items are not displayed on screen: register, setting, adjustment menu, channel call and volume bar. On the wide-screen models, an input selection is immediately made because the menu is not displayed.
At the "Limited" setting, some items cannot be displayed on screen. On the Japan-destined models, the channel call "Message" alone cannot be displayed. (This is because the channel call message may be confused with a message being sent from the hotel.)
On the North America-destined models, the OSD works the same as at the "No" setting.
Keys falling under any of the following items become invalid. Appearance of screen changes and the sound changes. Personal functions which are hard to restore. Screen display, menu, OFF-timer, ON-timer, AV MODE, screen size switching, clock setting, treble emphasis, AUDIO ONLY, sound changeover, LANGUAGE, CLOSED CAPTION
Simple input switching is generated. Those which are restored soon after leaving as they are and may be requested for change by customer are not prohibited. Brightness sensor (BACKLIGHT) and PIC. FLIP
Such a caution which is displayed independently is displayed as it is. Non-responding signal caution
When CC has already been ON, CLOSED CAPTION is displayed.
INPUT MODE START [NORMAL / TVA(24) / INPUT1 / INPUT2 / INPUT3 / INPUT8 / HDMI / HDMI2 / HDMI3 / PC] In power-ON, the input source to be started or channel can be set. (In standard mode, the operation follows the last memory.)
All the input sources in the model are made selectable. In TV mode, the channel to be set follows the last memory and the content of the last memory is included in the notation by options. Ex.) Air (2), Cable (98.1) etc.
The display of channel setting menu and the channel setting operation are prohibited.
In setting at "Normal", the setting of "Input mode fixed" is changed to "Variable" and selection should be prohibited.
INPUT MODE FIXED [VARIABLE / FIXED / AC CTRL / CR/RC CTRL ] At the "Fixed" setting, the TV set gets started with the settings of "Input mode start", and then any other channels and inputs are not accepted.
At the "ACON (AC CTRL)" setting, the TV set gets started with the settings of "Input mode start" under AC control.
At the "AC/RCON (AC/RC CTRL)" setting, the TV set gets started with the settings of "Input mode start" under either control.
With the execution of hotel mode, the input source is forced to change to that set by "Input mode start" and the channel switching and input switching are prohibited thereafter.
ON-timer's (Wake-up timer) channel items are not displayed or the operation is prohibited. (Basically, they are not displayed.)
The following keys are invalidated. CH up/down, direct tuning button, FLASHBACK, input
However, the keys (input switching and CH up/down keys) of the unit for menu operation remain valid.
In the following case, setting is cancelled and mode is changed to "Variable". When the setting of "Input mode start" is set to "Normal".

EXECUTE  


Activating service mode

  • Make sure the TV is switched off (not in standby)
  • While keeping the 'INPUT' and 'MENU' buttons on top of the TV pressed, switch on the power, until 'Service Mode' and '---' appears.
  • Enter the 3-digit entry code: 810


Note: According to the service manual to enter adjustment mode the following procedure should be followed (it did not work for me, though):
  • Make sure the TV is switched off (not in standby)
  • While keeping the 'VOL-' and 'INPUT' buttons on top of the TV pressed, switch on the power, until the letter 'K' appears.
  • Then hold the 'VOL-' and 'P-' buttons on top of the TV pressed, until multiple lines of blue characters appear.


When in service mode:
  • Use Program up/down to go to the next line
  • Use Cursor up/down to get to the next page
  • Use Cursor Left/Right to change an item (+10/-10)
  • Use Volume Up/Down to change an item (+1/-1)
  • Use INPUT to select a different input
  • Use RETURN to return to a present page
  • Use Enter for executing a function

Here is a printout of the 16 pages of service mode from a KRL-32V.
Note that some settings are TV specific.
Also note that I have no idea what most settings do...., or what the effect will be (you might render your TV inoperable!).
