Option Settings
6.4.1
Introduction
The microprocessor communicates with a large number of I
ICs in the set. To ensure good communication and to make
digital diagnosis possible, the microprocessor has to know
which ICs to address. The presence / absence of these
MT5301B ICs is made known by the option codes.
Notes:
•
After changing the option(s), save them by pressing the OK
button on the RC before the cursor is moved to the left,
select STORE and press OK on the RC.
•
The new option setting is only active after the TV is
switched "off" / "stand-by" and "on" again with the mains
switch (the NVM is then read again).

Option Code Overview
Enter SAM mode to check the option codes. they could not be
edited in the NVM.
6.4.3
Display Code Overview
Press the following key sequence on a standard RC
transmitter: "062598" directly followed by MENU and "xxx",
where "xxx" is a 3 digit decimal value of the panel type: see
column "Display Code" in
Code, restart the set immediately.

Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service
repair shop (SSB repair on component level) implies the reset
of the NVM on the SSB.
A repaired SSB in Service should get the service Set type
"00PF0000000000" and Production code "00000000000000".
Also the virgin bit is to be set. To set all this, you can use the
ComPair tool or use the "NVM editor" and "Dealer options"
items in SAM (do not forget to "store").
After a repaired SSB has been mounted in the set (set repair
on board level), the type number (CTN) and production code of
the TV has to be set according to the type plate of the set. For
this, you can use the NVM editor in SAM. The loading of the
CTN and production code can also be done via ComPair
(Model number programming).
In case of a display replacement, reset the "Operation hours
display" to "0", or to the operation hours of the replacement
display.

SSB Identification
SSB's of this chassis are identified by a "715" code on the SSB.
715Axxxx-Nnn-MMM-OOOO
•
715 main category, Printed Wiring Board
2
C
•
Axxxx sub category, sequential coding number
•
Nnn Version code
•
N Development number
•
nn Production number
•
MMM Mounting variation code
•
OOOO Optional variation code
Make sure when replacing an SSB the SSB identification codes
match the replacement board.
6.5.2
Cable position numbers
In wiring diagrams of this manual the position numbers of the
cables are not shown. These position number however can be
derived from the connector numbers those cables are
connected to.
To determine the position number of the cable, an "E" should
be prefixed to the connector number of the connector where
the cable initiates from.
For example, a cable from the PSU connector CN902 to the
SSB connector CN701, will have the position number ECN902.
The order is always seen from where the power initiates from.
So from PSU to SSB, from SSB to IR/LED panel, from IR/LED
panel to keyboard control panel.
