PHILIPS 42PFL5604-77 - SERVICE MODE – ERROR CODES [LED BLINKING CODES] DETAILS

APPLICABLE TO _ PHILIPS 32PFL5604-78__ PHILIPS 32PFL5604-77__ PHILIPS 42PFL5604-77 - SERVICE MODE – ERROR CODES [LED Blinking codes] Details.

SERVICE MODES

Note: For the new model range, a new remote control (RC) is used with some renamed buttons. This has an impact on the activation of the Service modes. For instance the old “MENU” button is now called “HOME” (or is indicated by a “house” icon).  Service Default mode (SDM) and Service Alignment Mode (SAM) offer several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call centre and the customer.  This chassis also offers the option of using ComPair, a hardware interface between a computer and the TV chassis. It offers the abilities of structured troubleshooting, error code reading, and software version read-out for all chassis.

SDM [Service Default Mode]

To start the blinking LED procedure where only layer 2 errors are displayed.

TO ACTIVATE THE SDM

Use the standard RC-transmitter and key in the code “0 6 2 5 9 6”, directly followed by the “MENU/HOME” button. After activating this mode, “SDM” will appear in the upper right corner of the screen (when a picture is available).

TO NAVIGATE THROUGH SDM

When the “MENU” (or HOME) button is pressed on the RC transmitter, the set will toggle between the SDM and the normal user menu (with the SDM mode still active in the background).
TO EXIT THE SDM

Switch the set to STAND-BY via the RC-transmitter.

SAM [Service Alignment Mode]

1.To perform (software) alignments.
2. To change option settings.
3. To easily identify the used software version.
4. To view operation hours.
5. To display (or clear) the error code buffer.

To activate SAM

Via a standard RC transmitter: key in the code “0 6 2 5 9 6” directly followed by the “ i/I NFO” button.

Contents of SAM

* Syst. Info. Giving overview of: – Op. Hours. During the life time cycle of the TV, a life time is kept. It counts the normal operation hours, not the Stand-by hours. The actual value of the life timer is displayed in SAM in decimal value. For every two startups the counter increases by one. Min. 5 digits are displayed in decimal digits. In detail:
* Every 2x cold start-ups, to display a picture, increases the counter by 1 (i.e. interrupt the mains supply 2x while the set is ON).
* Every 2x warm start-ups (from Stand-by), to display a picture, increases the counter by 1.
* Every hour of normal operating increases the counter by 1 (i.e. if a set is continue ON for 2 hours, then increase the counter by 2).
* Stand-by hours are NOT counted.

Main SW ID. > Displays the loaded main SW version.
Error Clear Codes. 

When “arrow right” is pressed and then the “OK” button is pressed, the error buffer is reset.
* Options. Choosing the CTN will set the options, see also
* RGB Align. This will activate the alignments sub-menu.
* NVM Editor. This will give the opportunity to directly change values in the NVM by selecting the address and value. Use decimal values.

NVM Copy. For easy transfer of NVM settings:
> Copy to USB. To upload several settings from the TV to an USB stick. See 5-1 USB Copy content. To upload the settings, press “arrow right” (or the “OK button), confirm with “OK” and wait until “OK” appears. Now the settings are stored onto the USB stick can be used to download to another TV or other SSB. Uploading is of course only possible if the software is running and if a picture is available. This method is created to be able to save the customer’s TV settings and to store them into another SSB.

> Copy from USB. To download several settings from the USB stick to the TV. Same way of working as with uploading. To make sure that the download of the channel list from USB to the TV is execute properly, it is necessary to restart the TV and tune to a valid preset if necessary.

USB Copy content

> Tuner. This will activate the alignments sub-menu.

Tuner AGC (RF AGC Take Over Point Adjustment)
> Auto ADC. This will activate the alignments sub-menu.

TO NAVIGATE

* In SAM, the menu items can be selected with the “Arrow up/down” ( ▲/▼)key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the “Arrow up/down” key to display the next/previous menu items. * With the “Arrow Left/Right” (◄/►)keys, it is possible to: > (De) activate the selected menu item.
> (De) activate the selected sub menu.
* With the “OK” key, it is possible to activate the selected action.
* With the “Menu/Home” key, it is possible to go back to the previous selection.

TO EXIT THE SAM

Switch the set to STAND-BY via the RC-transmitter.

ERROR CODES

  The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from top to bottom (or left to right), new errors are logged at the top/left side, and all other errors shift one position to the bottom/right.  When an error occurs, it is added to the list of errors, provided the list is not full. When the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained).  To prevent that an occasional error stays in the list forever, the error is removed from the list after more than 50 hrs. of operation.

There is a simple blinking LED procedure for board level repair (home repair) the so called LAYER 1 errors, next to the existing errors which are LAYER 2 errors:
* LAYER 1 errors are one digit errors
* LAYER 2 errors are two digit errors.

When is LAYER 1 or 2 available
* In CSM mode: When entering CSM: error LAYER 1 will be displayed by blinking LED. Only the latest error is shown.
* In SDM mode: When SDM is entered via Remote Control code, LAYER 2 is displayed via blinking LED.

ON-SCREEN ERROR DISPLAY

* In CSM, no error codes are displayed on screen.
* In SAM, the complete error list is shown.

  If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error code and not the actual cause (e.g. a fault in the protection detection circuitry can also lead to a protection).  In case of non-intermittent faults, clear the error buffer before starting to repair (before clearing the buffer, write down the content, as this history can give significant information). This is to ensure that old error codes are no longer present.

TO READ ERROR BUFFER

Use one of the following methods
* On screen via SAM (only when apicture is visible). E.g.:
> 000 000 000 000 000: No errors detected
> 017 000 000 000 000: Error code 17 is the last and only detected error.
> 015 017 000 000 000: Error code 17 was first detected and error code 15 is the last detected error.
*  Via the Blinking LED procedure.
*  Via ComPair.

TO CLEAR ERROR BUFFER

Use one of the following methods:
* By activation of the “Clear Codes” command in the SAM menu.
* With a normal RC, key in sequence “062599” followed by “OK”

Take notice that some errors need several minutes before they start blinking or before they will be logged. So in case of problems wait 2 minutes from start-up onwards, and then check if the front LED is blinking or if an error is logged.

LAYER-1 & LAYER-2 CODE Overview

LED BLINKING PROCEDURE {Layer-2 codes]

The software is capable of identifying different kinds of errors.  Because it is possible that more than one error can occur over time, an error buffer is available that is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly.  Errors can also be displayed by the blinking LED procedure.  The method is to repeatedly let the LED pulse with as many pulses as the error code number, followed by a time period of 1.5 seconds in which the LED is “off”. Then this sequence is repeated.
E.g. error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence the LED will be “off” for 1.5 seconds. Any RC command terminates this sequence.

Displaying the entire error buffer
The entire error buffer can be displayed when service mode “SDM” is entered (by remote control command 062596 >MENU). When in protection, this sequence will not work, but than LAYER-1 error code should suffice.  In order to avoid confusion with RC signal reception blinking, this blinking procedure is terminated when a RC command is received.

How to Activate
Use one of the following methods:
1. Activate the CSM. The blinking front LED will show only the latest LAYER-1 error.
2. Activate the SDM. The blinking front LED will show the entire contents of the LAYER-2 error buffer.

The procedures given above are common to 90% of LCD TVs; made by PHILIPS; irrespective to its screen size.
