Philips SL5 and WDRF02-FL – CRT TV – How to enter service mode - schematic - LED blinking codes

Service Default Mode (SDM)

How to Enter

To enter SDM, use one of the following methods:

• Press the following key sequence on the remote control transmitter: '0 6 2 5 9 6' directly followed by the 'MENU' button (do not allow the display to time out between entries while keying the sequence).

• Short jumper wires 9252 and 9275 on the family board and apply mains. Then press the power button (remove the short after start-up). Caution: Entering SDM by shorting wires 9252 and 9275 will override the +8Vprotection. Do this only for a short period. When doing this, the service-technician must know exactly what he is doing, as it could damage the television set.

• Or via ComPair (with the ComPair ‘Tools’, it should be possible to enter SDM via the ComPair interface).

After entering SDM, the following screen is visible, with SDM in the upper right corner of the screen to indicate that the television is in Service Default Alignment Mode.

Service Alignment Mode (SAM)

How to Enter
To enter SAM, use one of the following methods:
• Press the following key sequence on the remote control transmitter: '0 6 2 5 9 6' directly followed by the “On Screen Display icon “i +” button (do not allow the display to time out between entries while keying the sequence).
• Or via ComPair.
After entering SAM, the following screen is visible, with SAM in the upper right corner of the screen to indicate that the television is in Service Alignment Mode.

How to Navigate
• In SAM, select menu items with the MENU UP/DOWN keys on the remote control transmitter. The selected item will be highlighted. When not all menu items fit on the screen, use the MENU UP/DOWN keys to display the next / previous menu items.
• With the MENU LEFT/RIGHT keys, it is possible to:
– Activate the selected menu item.
– Change the value of the selected menu item.
– Activate the selected submenu.
• In SAM, when you press the MENU button twice, the set will switch to the normal user menus (with the SAM mode still active in the background). To return to the SAM menu press the MENU or STATUS/EXIT button.
• When you press the MENU key in while in an SDAM submenu, you will return to the previous menu.

How to Store SAM Settings

To store settings changed in SAM leave the top level SAM menu by using the POWER button on the remote control transmitter or the television set.

How to Exit

To exit CSM, use one of the following methods:

• Press the MENU, STATUS/EXIT, or POWER button on the remote control transmitter.

• Press the POWER button on the television set.

Switch the set to STANDBY by pressing the POWER button on the remote control transmitter or the television set.

If you turn the television set off by removing the mains (i.e., unplugging the television) without using the POWER button, the television set will remain in SAM when mains is re-applied, and the error buffer is not cleared.

Error Codes
The error code buffer contains all errorHow to Read the Error Buffer
You can read the error buffer in 3 ways:
• On screen via the SDAM (if you have a picture).
Examples:
– ERROR: 0 0 0 0 0 : No errors detected
– ERROR: 6 0 0 0 0 : Error code 6 is the last and only
detected error
– ERROR: 9 6 0 0 0 : Error code 6 was detected first and
error code 9 is the last detected (newest) error
• Via the blinking LED procedure (when you have no picture). See 'The Blinking LED Procedure'.
• Via ComPair.s detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is displayed at the left side and all other errors shift one position to the right.

How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
• By using the CLEAR command in the SDAM menu:
– To enter SAM, press the following key sequence on the remote control transmitter: '062596' directly followed by the “OSD" icon button (do not allow the display to time out between entries while keying the sequence).
– Make sure the menu item CLEAR is highlighted. Use the MENU UP/DOWN buttons, if necessary.
– Press the MENU RIGHT button to clear the error buffer. The text on the right side of the 'CLEAR' line will change from 'CLEAR?' to 'CLEARED'
• If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.

If you exit SAM by disconnecting the Mains from the television set, the error buffer is not reset.

In case of non-intermittent faults, write down the errors present in the error buffer and clear the error buffer before you begin the repair. This ensures that old error codes are no longer present.

If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error and not the actual cause of the problem (for example, a fault in the protection detection circuitry can also lead to a protection).

The Blinking LED Procedure

Using this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful when there is no picture.

When the SDM is entered, the LED will blink the contents of the error-buffer:

• When all the error-codes are displayed, the sequence finishes with an 'on' LED blink of 1.5 seconds,

• The sequence starts again.

Example of error buffer: 12 9 6 0 0

After entering SDM, the following occurs:

• 1 long 'on' blink of 5 seconds to start 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 followed by a pause of 1.5 seconds,

• 1 long 'on' blink of 1.5 seconds to finish the sequence,

• The sequence starts again at 12 short blinks.
