LCD SERVICE MODE AND POWER SUPPLY CIRCUIT

SERVICE MODE
|
Service Default mode (SDM) and
Service Alignment Mode (SAM) offers 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.

Service Default Mode (SDM)
|
Purpose
# To create a pre-defined
setting, to get the same measurement results as given in this manual.
# To override SW protections detected by stand-by processor and make the TV start up to the step just before protection (a sort of automatic stepwise start up). See paragraph “Stepwise Start Up”. # To override SW protections detected by Mips. See also paragraph “Error codes”. # To start the blinking LED procedure (not valid for protections detected by stand-by software). |
How to
Activate SDM
|
For this chassis there are two
kinds of SDM: an analog SDM and a digital SDM. Tuning will happen according
table “SDM Default Settings”.
# Analog SDM: use the standard
RC-transmitter and key in the code “062596”, directly followed by the “MENU”
button.
Note:It is possible that, together with the SDM, the main menu
will appear. To switch it “off”, push the “MENU” button again.
# Digital SDM: use the standard
RC-transmitter and key in the code “062593”, directly followed by the “MENU”
button.
Note:It is possible that, together with the SDM, the main menu
will appear. To switch it “off”, push the “MENU” button again.
# Analog SDM can also be
activated by shortening for a moment the two solder pads [1] (see figure
“Service mode pads”) on the SSB, with the indication “SDM”. Activation can be
performed in all modes, except when the set has a problem with the Stand-by
Processor.
