Introduction
The microprocessor communicates with a large number of I
2
C
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
MT5591 ICs is configured 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).
6.4.2
Option Code Overview
Enter SAM mode to check the option codes. they could 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
. After resetting the Display
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
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.
6.5.1
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
•
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 panel.
