In this manual some parts can be changed for improving. Their
performance without notice in the parts list. So, if you need the latest parts information, please refer to PPL(Parts Price List) in Service
Information Center.
Points from 3 show data for DLT models.

1. Safety Precautions
(1) When moving or laying down a LCD Set, at least two people must work together. Avoid any
impact towards the LCD Set.
(2) Do not leave a broken LCD Set on for a long time. To prevent any further damages, after
checking the condition of the broken Set, make sure to turn the power (AC) off.
(3) When opening the BACK COVER, you must turn off power (AC) to prevent any electric
shock.
(4) When loosening screws, check the position and type of the screw. Sort out the screws and
store them separately for reassembling. Because screws holding PCBs are working as electric circuit grounding, make sure to check if any screw is missing when assembling / reassembling. Do not leave any screws inside the set.
(5) A LCD Set contains different kinds of connector cables. When connecting or disconnecting
cables, check the direction and position of the cable beforehand.
(6) Connect/disconnect the connectors slowly with care especially FFC (film) cables and FPC
cables. Do not connect or disconnect connectors instantaneously with force, and handle
them carefully for reassembling.
(7) Connectors are designed so that if the number of pins or the direction does not match,
connectors will not fit. When having problem in plugging the connectors, check their kind,
position, and direction.

6. Trouble Shooting
* Facts you must know at trouble diagnosis or repairing
(1) The trouble diagnosis and repairing of set means Module .
In other words, find out which PCB modules are not working and replace them with normal PCB
modules.
(2) This TROUBLE SHOOTING list only contains representative and simple PCB trouble diagnosis and
Module Exchange method. Therefore, if you find Sets which are difficult to diagnose or to repair,
contact Daewoo Electronics.

12. Software Install & Upgrade
I. Analog software upgrade.
! Software installation requires - Microsoft.NET Framework Version min. 1.1
it is available at http://www.microsoft.com/net/
1. Equipment needed for analog software upgrade.
a). Computer with serial port (RS232) or with USB to RS232 converter.
Alternatively extention RS232 cable.
USB to RS232 converter
computer with serial port
b). RS232 upgrade JIG
2. Hardware installation.
Before start!
Please check if your computer has serial port, if not please install converter USB to RS232.
a). Turn off computer.
b). Connect RS232 upgrade JIG to serial port.
(If needed use extention RS232 cable.)
c). Turn On computer.
3. Software installation.
a). DAEWOO GProbe folder include three files:
- CGProbe Redistributable 5.7.0.1.exe,
- Readme.txt,
- setup.exe.
Before install DAEWOO_GProbe application please install first Microsoft .NET Framework

62
Page 64
Software Install & Upgrade
4. Software configuration.
a). Start application DAEWOO GProbe
After start application you need to set Port, Speed,
AppsTest (depends on PCB state), Flash image, Flash
driver or if you switch on Batch file mode then you need
to choose Batch file.
In the next points you can find more explanations.
b). Port
Port settings depend on your hardware configuration
c). Speed
Speed should be set to option 115200.
63
Page 65
Software Install & Upgrade
d). AppsTest
This setting depends on PCB state.
When you want to program PCB without sofware, then this
option should be OFF (not mark).
In case of upgrade software to newer version you need to
switch AppsTest option ON.
If this option is not corect you will have problem with programming IC.
Optional you can set AppsTest to OFF and forced
AppsTest manually on the PCB using jumper and switch
(more explanations at point 5).
e). Batch file (*.txt)
If you want to use Batch file to programming IC, you
need to switch ON (mark) Batch file option and choose
file using Browse button.
f). Manual mode
In Manual mode you need to set Flash image
(*.bin,*.hex) and Flash driver (*.bin,*.hex)

5. Chassis SL-150 programming procedure for Genesis IC - PCB part.
If you adjust correctly application settings then you need to prepare PCB for programming.
Photo below shows normal state of PCB (model 20”). The most important point which can be use for programming you can find as a marked point from 1 to 4.
1 - Jumpers J1 (on PCB loc. P201-206).
2 - Switch SW1 (on PCB loc. SW502).
3 - Jumper J2 (loc. JP01).
4 - Programming port P1 (loc. P508).
For programming you need to switch off
the TV-set and remove backcover.
Next make PCB configuration:
- remove jumpers J1 (please note configuration to restore them after software
upgrade),
- replace 4-pins connector in port P1 with
RS232 upgrade JIG connector (in some
cases 4-pins connector showed on photo
point 4 will be not present),
(PCB photo 1 )
Next PCB photo show properly prepared PCB for upgrade software.
1-4 same like above
5 - RS232 upgrade JIG
6 - USB to RS232 converter

If you finish prepare PCB to pogramming procedure then you can switch on TV-set to normal operating
mode (not stand by mode!!!).
Additional information:
AppsTest mode you can received during normal operating of TV-set if you will follow procedure:
- step 1 - add jumper J2,
- step 2 - push switch SW1,
- step 3 - remove jumper J2.
After this 3 steps you don’t need to switch ON (mark) option AppsTest at DAEWOO GProbe application.
6. Chassis SL-150 programming procedure for Genesis IC - application part.
If you want to use batch file, you need to prepare special .txt file.
Below you can find listing of example batch file:
In case of manual mode you should follow to the instruction from point 4.
So you need to choose correct value for Port, Speed, AppsTest and then you need to select correct version
of MICOM software and Driver.
a). Example of correctly adjusted DAEWOO GProbe
application.
After that you can start programming procedure by pressing Start button.
66
Page 68
Software Install & Upgrade
b). During programming you will see yellow information
window with text about current state and commands
results.
You can see also progress bar.
c). If programming procedure successfully finish then
the colour of text window will change to green. As a
summary you will see writing time and text
„PROGRAMMING SUCCESSFULLY!!! „.
Important information!!!
If you finish upgrading software to newer version it is needed to make NVM reset by command „NVRAM Fill”.
Desctription how to make it you can find in next point of instruction.
After finish programming you should:
- switch off the TV-set,
- restore configuration of PCB jumpers J1,
- replace 4-pins connector port P1 with original one - see PCB photo 1 (in some cases 4-pins connector - PCB
photo 1 -> point 4 - will be not present),
- assembly backover and switch on TV-set
67

Software Install & Upgrade
7. Chassis SL-150 - NVM reset procedure.
a). Please make instructions from point 5 („Chassis SL-150
programming procedure for Genesis IC - PCB part.”) and
then please choose
„Menu -> Commands -> Terminal1 -> NVRAM Fill”
b) New window „Terminal1 NVRAM Fill” should
appears.
c). Please fill form using values:
Address=”0”, Length=”4096”, Value=”0xFF”,
and then press „Execute”
d). If „NVRAM Fill „ procedure successfully finish then
the colour of text window will change to green. As a
summary you will see text „COMMAND
SUCCESSFULLY!!! „.
If command „NVRAM Fill „ failed then the colour of text window will change to red and appear info „Error !!! „.
In that case please try one more time same operation.
After successfully finish NVM reset you need to switch off and on TV-set.
The first startup procedure will be longer because of writing initial values to NVM.

8. Remarks.
During programming sometimes errors can happend.
You will see that when text window in DAEWOO GProbe application change colour to red.
There will be also text information where problem appears.
Below you can see two examples of errors which can appear during programming procedure.
a). Problem with serial port, for example in this situation
you should check Port configuration - possible reason:
selected Port is not correct or port is not present in
system devices menager.
b). There is problem with connection to TV-set, in this
situation you should check if TV-set is properly ON (not
in stand by), RS232 upgrade JIG is properly connected
to serial port and to TV-set or RS232 is broken.
If during programming you will see error information you should:
* try flash it one more time,
* check software configuration,
* try to change serial port (if it is possible),
* check supply voltage,
* check all required connections.
