PHILIPS - BELT - LC7.2E _ CHASSIS _ SERVICE MODE

TO ACTIVATE SERVICE DEFAULT MODE [SDM]

• Press the following key sequence on the remote control transmitter: “062596” directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence).
•  Short one of the “Service” jumpers on the TV board during cold start (see Figures “Service jumper”). Then press the mains button (remove the short after start-up).

Caution: Activating SDM by shorting “Service” jumpers will override the DC speaker protection (error 1), the General I2C error (error 4), and the Trident video processor error (error 5). When doing this, the service-technician must know exactly what he is doing, as it could damage the television set.

TO NAVIGATE

• Command MENU from the user remote will enter the normal user menu (brightness, contrast, colour, etc...) with “SDM” OSD remaining, and pressing MENU key again will return to the last status of SDM again.
•  To prevent the OSD from interfering with measurements in SDM, command “OSD” (“STATUS” for NAFTA and LATAM) from the user remote will toggle the OSD “on/off” with “SDM” OSD remaining always “on”.

     Press the following key sequence on the remote control transmitter: “062596” directly followed by the OSD/i+ button to switch to SAM (do not allow the display to time out between entries while keying the sequence).

TO EXIT SERVICE MODE

• Switch the set to STANDBY by pressing the mains button on the remote control transmitter or on the television set. 
• If you switch the television set “off” by removing the mains (i.e.,unplugging the television), the television set will remain in SDM when mains is re-applied, and the error buffer is not cleared.  The error buffer will only be cleared when the “clear” command is used in the SAM menu.
• If the TV is switched “off” by a power interrupt while in SDM, the TV will show up in the last status of SDM menu as soon
