DIS-ASSEMBLY PROCEDURES
NOTE: There is no need to the pals tic back back cover to service a PCB or speaker.
Upper Back Cover Removal

• Remove 12 screws.
• Remove three screws.
• Lift cover up to dislodge from pegs, and remove the cover.

Lower Center Back Cover

1. Remove 3 screws {B}.
2. Remove 8 screws {C}

Service Position.  Unplug the AC cord from AC mains wall socket.  This service position exposes the entire bottom side of the Power Supply Panel [PSP], Large Signal Panel [LSB], and Small Signal Panel [SSM].  A major portion troubleshooting can be accomplished after completing this procedure.

Remove Lower Back Cover.

• Remove 12 screws { B & C}

• Loosen the Chassis Frame.  Remove 5 screws [D] that fasten the Chassis Frame to the Cabinet Bottom.

Service Position Detail -A

Remove Light Barrier.  Service Detail - B

• Remove 2 screws from the left side - Light Barrier guide, and remove this guide.
• Gasp the corners of the Chassis Frame and slide in towards out about an inch.  This is required in order that the three metal cleats holding the front edge of the Chassis Frame are released.
• While holding the back edge of the Chassis Frame down, gasp the panel mounting Bracket and slightly lift the front of the Chassis Frame.
• Service Detail -C

• With the rear of the chassis slightly raised, slid the center chassis forward, just far enough that the Rear Jack Panel clears the left side mounting block.  
• Service position detail - D

• Now, lift the back edge of the Chassis Frame up while also lifting the front edge to slide forward into the Service Position
• Service position detail - E

REAR JACK PANEL COVER

Complete all steps to make the Service Position proedure as described above.

• With the Chassis loose from the cabinet bottom, and the entire chassis re positioned back towards the Cabinet Front, lift the left end of the Chassis Assembly in order to remove the previously hidden screw shown on the following detail.  This screw may be removed by using a 1/4" nut driver or a T20 Torx Driver.  In either case, and extension may be required in order to achieve the proper angle to the head of the screw.

• Remove 2 screws from the left edge and upper left corner of the Rear Jack Panel Cover.  These two screws may be removed using a 1/4" nut driver.
• Remove the nut around the 75 Ohm antenna input
• Remove 10 more screws shown in the following using a Torx 10 Driver.

• Disconnect 2 connectors from the top of the rear switch panel.  This panel fastens to the jack panel cover and may easily be removed or re connected once the jack panel cover is completely free of the chassis assembly.
• Although all screws should now have be removed, care must be taken on core models featuring the HD input.  The jack panel cover has a plastic hook that clips into a hole on the the DVI panel.  Gently lift this hook while removing the jack panel.

PHILIPS Dali 32PFL3605D 40PFL3605D LED BLINKING CODES

     Errors can also be displayed by the Blinking LED procedure.  The method is to repeatedly  let the front LED pulse with as many pulses as the error code number, followed by a period of 1.5 seconds in which the LED is Off.  The the sequence repeats:
     For example, error code '4' will result in four times in sequence LED 'on' for 0.25 seconds / LED 'off' for 0.25 seconds.   Any remote control command terminates the sequence.  Error code LED blinking is in red color.
     Example: The content of the error buffer is "12 9 6 0 0"  After entering SDM, the following occurs [Method to enter SDM has been described in the previous post].

• 1 long blink of 5 seconds to start up the sequence.
• 12 short blinks followed by a pause of 1.5 seconds,
• 9 short blinks followed by a pause of 1.5 seconds, 
• 6 short blinks followd by a pause of 1.5 seconds,
• 1 long blink of 1.5 seconds to finish the sequence, 
• The sequence starts again with 12 short blinks.

DISPLAYING THE ENTIRE ERROR BUFFER

The entire buffer is displayed when Service Mode "SDM" is entered.  In case the TV set is in protection or standby: The blinking LED procedure sequence; as in SDM mode in normal operation; must be triggered by the following Remote command sequence:

" Mute => '062500' => OK"

In order to avoid confusion with remote control signal reception blinking, this blinking procedure is terminated when a remote control command is received.

ERROR CODES AND DEFECTIVE PART [BOARD]

Layer-1 error code	Defective board	Layer-2 error code	Defective board
2	SSB	11	Speaker DC protection active on SSB
4	IPB	12	+12 missing | low, IPB defective, Power_Down.
4	IPB	13	POK line defective
2	SSB	15	EEPROM I2C error on SSB, M24C16.
2	SSB	16	Tuner I2C error on SSB.
2	SSB	18	IF demodulator I2C error on SSB, TDA9886.

The 'Layer-1' codes are pointing to the defective board.  They are triggered by LED blinking when CSM is activated.  In LC 10- platform , only two boards are present:  The SSB & PSU | IPB, meaning only the following layer-1 errors are defined.

2: SSB

4: PSU | IPB.

HOW TO READ ERROR BUFFER

• On screen via the SAM | SDM | CSM
• ERROR: 0 0 0 0 0 ; No errors detected.
• ERROR: 6 0 0 0  0; Error code '6' is the last and only error detected.
• ERROR: 9 6 0 0 0; Error code '6' was detected first & error code '9' is detected; newest; error. 

The last found error is displayed on the left.  An error with a designated error code may never lead to a deadlock situation.  This means that it must be always be diagnosable.

3. Customer Service Mode [CAM]
4. Computer Aided Repair [ComPair]

SDM & SAM offer features, which can be used by the service technician to repair | align the set.  Some feature are:

• A pre-defined situation to ensure measurements can be made under uniform conditions.[SDM]
• Activates the blinking LED procedure for error identification when no picture is available. [SDM]
• The possibility to overrule software protections when SDM is entered  via the service pins.
• Make alignments, such as White Tone, De-select options, enter option codes, reset the error buffer [SAM]
• display information; SDM or SAM indication in upper right corner of the screen, error buffer, software version, operating hours, options and option codes, sub menus etc:

SERVICE DEFAULT MODE [SDM]

• To activate SDM, use one of the following methods.
• Press the following key sequence on the remote control [0 > 6 > 2 > 5 > 9 > 6 ] followed by Menu] button (or)
• Short one of the service pads on the TV board during cold start.  Then press the mains button; remove the short after start up.
• Caution:  When doing this the technician must know exactly what he is doing, as it could damage the TV set.

Service Pads [SSB component side]

ON SCREEN MENU

Menu items and explanations

• xxxxx: Operating Hours in Decimal.
• AAAAAB-XX.YY: Software identification.
• ERR:  Shows all errors detected since the last time the buffer was erased in format <xxx> <xxx> <xxx> <xxx> (five errors possible).
• OP:  Used to read-out the option bytes.  Ten codes (in two rows) are possible.

TO NAVIGATE

In the SAM menu, select menu items with UP | DN keys on the remote control.  The selected item will be indicated.  When all menu items not fits on the screen, use Up | Dn keys to display next | previous menu items.

With Left | Right keys, it is possible to 

- Activate selected menu item.

- Change the data value to selected item.

- Activate the selected Sub-Menu.

When Menu button is pressed twice while in top level SAM, the set will switch to normal user menu; with SAM mode still active in the background.  To return to SAM menu press 'Menu' button.

The "[i] INFO" key from user remote control will toggle the OSD On | Off with SAM OSD remains always ON.

Press [0 > 6 > 2 > 5 > 9 > 6] directly followed by "Menu" button to switch to SDM; do not allow the display to time out between entries while keying the sequence.

To "EXIT" switch the SET to Standby by pressing the mains button on the remote control or the TV set.
