How to UPGRADE SUB-MICOM WITH DDC MANAGER – USB DOWNLOAD METHOD

SAMSUNG UE32C5*** - UE37C5*** - UE40C5*** - UE46C5*** - UE32C4000P* - LED TV

USB UPGRADE PROCEDURE
Samsung may offer upgrades for TV’s firmware in the future. Please contact the Samsung call center to receive information about downloading upgrades and using a USB drive. Upgrades will be possible by connecting a USB drive to the USB port located on your TV.

> Insert a USB drive containing the firmware (T-TDT5DEUC) upgrade into the USB port on the rear of the TV.
> Press the MENU button to display the menu.  Press the or button to select "Support", then press the ENTER button.
> Press the or button to select "SW Upgrade", then press the ENTER button.  The message "Scanning for USB. It may take up to 30 seconds." is displayed.
> The message "Upgrade version XXXX to version XXXX?  The system will be reset after upgrade." is displayed.
> Press the or to select the "OK", then press the ENTER button.

Be careful to not disconnect the power or remove the USB drive while upgrades are being applied. The TV will turn off and turn on automatically after completing the firmware upgrade.  Check the firmware version after the upgrades are complete. When software is upgraded, video and audio settings you have made will return to their default (factory) settings.
Write down your settings so that you can easily reset them after the upgrade.(Recommended)

HOW TO UPGRADE THE SUB-MICOM WITH DDC MANAGER
* Connect DDC MANAGER to the TV Set with D-SUB cable. And Power on.  (USB type : MTI-2510 / parallel type : MTI-2059)

* Enter the factory mode.  Control - EDID - EDID ON/OFF Select ON.
* Open the DDC tool. (Parallel type & USB type)

* Load the sub micom program fie (T-TDT5DEUS-XXXX.BIN).

* Push the ‘Program’ Button.  (It takes quite a bit of time. You can wait or close the DDC tool by force and open tool and load fie again.)

* Push the ‘Program’ Button again. (It takes about 100 seconds.)

If update completes, TV set will booting automatically. Disconnect the JIG.

> To enter the factory mode; press the remote control keys in this sequence [Power OFF > Info > Menu > Mute > Power On.]

If you want to enter the hidden factory mode.

# Enter into the factory mode first.

# Move the tap to Advanced

# Key in “0 + 0 + 0 + 0.  The hidden menu: Advanced will be displayed. Never enter factory mode and adjust the data values there, if you are not familiar with.  You should know, what you are going to do, and what will be the result.  Improper adjustments to data values here might make the set even in-operative; and irresponsive to any signal thereafter.

FLUKE 192B _196B-C _199B-C Scope-Meter SCHEMATIC

0
0
ATTENTIONNever attempt to open this instrument, unless you’re familiar with repairing measuring instruments.  This is a very delicate and accurate measuring instrument. 
BATTERY
Battery operating time is does not meet the specification (4 hours)
1. Turn the ScopeMeter on (battery power only)
2. Check the voltage across R4101 (near the battery connector) for about 140 mV. This corresponds to a current of about 0.95 A. If the current is much higher the cause of the problem is not the battery.  

Battery is discharged when ScopeMeter is not used for some time (2 or 3 weeks).
1. Turn the ScopeMeter on (battery power only)
2. Check the voltage across R4101 (near the battery connector) for about 0.15 mV.  This corresponds to a current of about 1 mA. Turn the ScopeMeter off and on, and check the voltage again for 0.15 mV. Do this about 10 times.  If one or more times a current of about 1.2 mV is measured (8 mA), the cause is a defective IC D3550. This IC takes care of a correct power state of D3500.  As the 8 mA discharge current can have damaged the battery, you must check the battery capacity as described below.
3. If the current is much higher then 8 mA the cause of the problem is not or is not only D3550 
To check if the battery has a correct capacity
1. Do a battery refresh

2. Disconnect the BC190 Battery Charger/Power Adapter
3. Start a TrendPlot: RECORDER
4. When the battery is discharged the ScopeMeter will shut down. Now connect the BC190, turn the power on and check the length of the TrendPlot trace. For a new battery pack this should be about 4 hours. Depending on the number of applied charge cycles the battery capacity will decrease. If the TrendPlot trace has a length of 3 hours or less you may consider to replace the battery pack.

Loading Software
To load a new software version in the test tool contact an authorized Fluke Service center.

ELPLODED VIEW
FLY-BACK CONVERTER
1. Check the fly back converter output voltages +5V2, +3V3GAR (+3.3 V), +3V45, +2V6, -1V8, -5V2 and +30V.  Check FLTPOWIN1and FLTPOWIN2 (6.5Vrms, ≈ 70 kHz) on for example T1102 pin 3 and pin 5.

a.If one or more voltages are correct, then check the rectifier diodes, coils, and capacitors of the incorrect voltage (s)
b. If none of the voltages is correct, then the fly back converter does not run correctly, continue at step 2.
2. Check VBATT for >7 V.
3. Check N4000:49 (FLYGATE) for a square wave voltage of at least some volts (for a correct Fly Back Converter 50...100 kHz, ≅8 Vpp).  If no square wave is present on N4000:49 go to step 4.  If a square wave is present on pin 49 (maybe not the correct value), then check N4000:55 (FLYSENSP) for a saw tooth voltage of 50...100 kHz, 300 mVpp.

a. If no sawtooth voltage is present on N4000:55, no current or a DC current flows in FET V4001. The primary coil of T4001 or V4001 may be defective. Check also R4101 (current sense resistor); it can be fused due to a short in FET V4001.
b. An incorrect sawtooth on N4000:55 can be caused by:
* overloaded outputs (Frequency too low, <<50 kHz)
* underloaded outputs (Frequency too high, >>100 kHz)
* bad FET V4001 (Sawtooth voltage is not linear).
4. Check N4000:62 (PWRONOFF) for >+3V. If wrong, see Section 7.5.13 Power ON/OFF.
5. Check N4000:43 (COSC) for a triangle wave form, 50...100 kHz, +1.6 V to +3.2 V.  If wrong check C4123 and connections; check IREF, see step 6.
If all correct, then replace N4000.
6. Check N4000:74 (IREF) for 1.6 V. If wrong:
a. Check N4000:73 (REFPWM2) for +3V3. REFPWM2 is supplied by N4000, and derived from REFP. Check N4000:72 (REFP) for 1.22 V. If wrong, check V4114 and connected parts.
b. Check R4021, replace N4000.
7. Check N4000:51 (VOUTHI) for <2.5 V (nominal value 1.8 V). If wrong check R4014 and connections to N4000.
8. Check N4000:57 (IMAXFLY) for 570 mV. If wrong check R4020 and connections to N4000.

TROUBLESHOOTING
* Check the various cable connections fist.
* Check to see if there is a burnt or damaged cable.
* Check to see if there is a disconnected or loose cable connection.
Check to see if the cables are connected according to the connection diagram.  Check the power input to the Main Board.  Check the Power input to the FRC(Frame Rate Conversion) Board.  Check internal Pattern both of FRC and FBE3 if there is some picture noise.
FRC: Factory mode (MUTE - BUTTON 1 - BUTTON 8 - BUTTON 2 - Power on) > FRCM > TP After DDR Press right button of Remocon.
FBE3: Factory mode (MUTE - BUTTON 1 - BUTTON 8 - BUTTON 2 - Power on) > FBE > Patt Sel > Press right button of Remocon.
Case1: FBE3 ok, FRC NG: change the FRC Board Case2: FBE3 NG: change the main Board.
Check the LED lamp for source button on front.
If this LED blank 100mS frequently then FRC board is defective (communication problem via Main board) in this case change the FRC board.

NO POWER
> The LEDs on the front panel do not work when connecting the power cord.
> The SMPS relay does not work when connecting the power cord.
The units appear to be dead.

The IP relay or the LEDs on the front panel does not work when connecting the power cord if the cables are improperly connected or the Main Board or SMPS is not functioning. In this case, check the following:
* Check the internal cable connection status inside the unit.
* Check the fuses of each part.
* Check the output voltage of SMPS.
Replace the Main Board.

NO VIDEO-Analog PC signal
Audio is normal but no picture is displayed on the screen.

> Check the PC source
> Check the SDP84 (ARSENAL)
This may happen when the LVDS cable connecting the Main Board and the Panel is disconnected.
