7. Plug the mains adapter in an mains outlet and switch on the
ComPair interface. The green and red LEDs light up
together. The red LED turns off after approximately 1
second, while the green LED remains lit.
8. Start the ComPair program and read the "introduction"
chapter.

Stepwise Start-up / Shut-down
Under normal circumstances, a fault in the power supply, or an
error during start-up, will switch the television to protection
mode. ComPair can take over the initialisation of the television.
In this way, it is possible to distinguish which part of the start-
up routine (hence which circuitry) is causing the problem.
Stepwise start-up explanation
This is realised via ComPair and is very helpful when a
protection is activated (see also paragraph "Protections").
Table 5-1 Stepwise Start-Up Table
State Mode description
0 - Low power standby
- uP in Standby.
1 - High power standby.
- TV-set in standby.
2 - Supply 'on'.
- Protections 5V2 and
8V6 activated.
3 - Sound ICs initialised.
- Protections FBX and
TUNER activated.
4 Not used in FTV
5 - TV operates.
- Unblanked picture.
Stepwise shutdown explanation
In the stepwise shutdown mode, state 2 and 4 are skipped.

Note (*): When the set is in stepwise mode and, due to
stepping-up, a protection is activated; the set will really go into
protection (blinking LED). The set will not leave the stepwise-
mode however. By stepping down, the set can be activated
again, until state X where the protection was activated. At state
(X-1) diagnostic measurements can be performed.

Error Codes
The error code buffer contains all detected errors 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 written at the left side and all other errors shift one
position to the right.
5.5.1
How to Read the Error Buffer
It is possible to read out the error buffer in three ways:
•
On the screen while in Service Alignment Mode (SAM). If
there is a picture, this is the easiest way to read the error
buffer. In the SAM main menu, the last 10 error codes,
which have occurred, are displayed. The most recently
detected error code is displayed on the left side. Examples:
–
003 000 000 000 000: error code 3 is the last and only
detected error.
–
002 003 000 000 000: error code 3 was detected first
and error code 2 is the last detected (newest) error.
•
With the CODE 1 and CODE 2 lines in CSM.
•
With ComPair.
5.5.2
How to Clear the Error Buffer
It is possible to clear the error buffer in two ways:
•
By selecting the item "reset Error Buffer" in the SAM main
menu.
•
By pressing the following key sequence on the remote
control transmitter: MUTE - 062599 - OK.
Note: When the error buffer is full (10 codes), no new errors
can be stored. The set monitors how long every error is stored
in the error buffer. If a false error is in the buffer, it will be
deleted after 50 hours. If an actual error is in the error buffer, it
will be written to the buffer again after 50 hours. This is a
safeguard to ensure that the history of the error codes is stored.
To help ensure that you are not reading false error codes, you
may want to record the contents of the error buffer, reset the
buffer, and see which error codes are generated again by the
set.
