SAMSUNG - CW29Z68PSG SERVICE MODE and ADJUSTMENTS

TO ENTER SERVICE MODE

• Press {Power Off => Display => Menu => Mute => Power On} keys in sequence to enter service mode. 

WHITE BALANCE ADJUSTMENT

• After enter the Service Mode, initilize all set data.
• Input a Toshiba pattern.
• Using Probe [CA100], do white balance adjustments.

TO ADJUST LOW-LIGHT

1. Adjust sub-brightness to set 'Y"
2. Adjust B-Cutoff to set 'y'
3. Adjust R-Cutoff to set 'x'

TO ADJUST HI-LIGHT 

1. Adjust sub-contrast to set 'Y'.
2. Adjust B-Drive to set 'y'.
3. Adjust R-Drive to set 'x'.

Check the value of low-light.  If necessary, adjust low-light.

Check the value of high-light.  If necessary, adjust hi-light .15.

SCREEN VOLTAGE ADJUSTMENT

• Screen voltage and white balance are related each other.  Make sure, both these adjustments are correct.
• Adjust screen voltage, before White Balance Adjustments.  Make sure the screen voltage is correct.
• If white balance has been re-adjusted, re-check screen voltage too.
• After adjustments has been done, check if there if spots appear on the screen after Power On/Off key.   If fly back line [thin white horizontal lines across the screen at about an inch apart, all over the screen], re-adjust the screen voltage to a little less.  It will be best to adjust screen voltage out from direct light.  A dark room is more preferable.

TOSHIBA - 42HP83 PLASMA - POWER SUPPLY SHUT DOWN PROBLEM

The main power supply section to this set have four boards.   Main Power _ Sub power _ Low B1 & Low B2.

The main power board produces a verity of supply voltages used by various boards in the set.   If a power supply panel has been replaced, or at the event of panel change, certain adjustments should be done.  These adjustments are [Vs, Va, Vsc, Vset & Ve]; determines the voltage supplied to plasma screen and are controlled by a variable resistor located on the plasma screen supply panel.     As incorrect voltage levels may cause 'shut-down' or screen damage, it is important to measure these voltages at each test points.  The voltage requirements will be clearly marked on the label of the panel.  

Shut-downs in the 43HP83 plasma receiver can be divided into [2] categories.  The unit can shut down due to a problem, such as an in-operational fan, or due to an over voltage condition.  Both these shut downs are noticed by the main microprocessor, but can be identified by error symptoms.'

#  Shut downs due to fan trouble simply cause the unit to turned off, and exhibit an error code by blinking the Power LED.  When this occur, the unit will be allowed to re-start by turning it Off and back On again.  In this situation technician normally will have enough time to trouble shoot the unit and in some cases read the error codes in the 'Service Menu'.

##  Over voltage shut down is a function of the power supply distribution system that latches the unit OFF when it occurs.  It will not attempt to start again until the set is unplugged from AC power socket.  When re-apply AC again, the same thing will repeat.  In addition to latching of unit, the shut down usually occurs immediately generate a Dead set, with no indication other than blinking power LED.  If this is the condition, make sure that it is with power supply regulator board itself.  

###  There is an over voltage protection circuit integrated with power main power board to detect any over voltage condition at its output voltages.  When the protect line in this circuit rises, the Gate of SCR [Silicon Controlled Rectifier] also will rise.  This will cause [D819] to conduct and apply DC voltage to the base of [Q819].  Q819 will conduct and the Power On line will be pulled low.  This causes the power relays in the unit to open.  As well as opening the relays and shutting the whole unit down.  When Q819 pulls the power line low, signal is send to main micro-controller realizing about it, and the unit starts blinking LED, indicating shut down.  

Since trouble shooting is done by board level, all that needs to be done is to determine, which among the two boards is causing shut down.  Actually this is the main part of service, where a technician should have give more concentration.   It is a must have its schematic diagram to follow the circuit.  Schematic diagrams can be downloaded from internet. With only a schematic diagram, user can't do any thing with it, as it will be a drawing which not resemble to anything with in the TV.  

If a voltage of about 1.8VDC appears across R872 as the unit is turned ON, it means that the shut down is being initiated by the 3.3VS1 source developed by the low B2 power supply.  If this is the case, Low B2 board should be replaced.  

Since this is the only source monitored on this board.  If no voltage is detected across R872, the shut down problem might be related to one of the low B1 sources and that board should be trouble shooed.  In most cases, it is advice to replace the board as card basis.  It will be best especially in case of Plasma TVs.  

Use the same method to check the sources developed by Low B1, and that board.  If confirmed faulty, replace the board.  Never try to repair it.

AIWA - VX1470PH SERVICE MODE

TO ENTER SERVICE MODE

• If a service repair is undertaken where it has been required to change the Memory IC, initial data set should be done.
• Initial data setting is not possible if clock has been set.  To reset clock, either unplug AC cord from main power wall socket and allow at least 30 minutes before Power On or discharge the backup capacitor

1. Enter Data Set Mode by setting volume to minimum[0]. 
2. While holding down the Volume Button on the front panel of the TV, press key [6] on the remote control handset simultaneously.  
3. Address and data will appear.
4. Address now selected will blink.
5. Use the [Set +/-] keys on the remote to step through the address until reviewed address to be changed is reached.
6. Press "Enter' to select the data.  When data is selected, it will blink.
7. Again, step through the data using [Set +/-] until required data value has been reacted.

TOSHIBA - 46H83 - 51H83 - 57H83 SERVICE MODE

APPLICABLE TO TOSHIBA: 46H83_46HX83_51H83_51HX83_57H83_57HX83_65H83_65HX83

ENTERING SERVICE MODE

• The V-Chip PIN code can be reset, if the service is required or the customer has forgotten the V-Chip PIN code, by pressing "RECALL" button on the remote [4] times within [5] seconds while at the PIN Code entry screen.

1. To enter service mode, press "Mute" button twice on the remote control.
2. Press "Mute" button again to keep pressing.
3. While pressing the "Mute" button press 'Menu" button on the front panel of the TV set.

On service mode, self check can be performed to test the SCA & SDL lines through the TV.

• Enter Adjustment Mode.
• Press the '9" key on the remote control to display self-diagnostic results on the screen.
• Pressing the "9" key again will return to Service Mode.
• Self diagnostic only shows one communication error at a time.  Once communication is restored, run the self diagnostic again until "OK" is displayed to verify there are no more errors.  

     Initialization of the self check is only required to clear the protect indicator (Power 000000).  All other indicators are cleared when the self check is excited.  To clear the power counter, push the "Recall" button on the remote control and "Channel Dn" button on the TV.

     While in service menu, do not push "Channel Up" on the TV and 'Recall' on the remote control.  This will cause initialization of memory IC.  After replacement of memory IC, this should be done.  

SELF DIAGNOSIS

• The microprocessor has a self diagnostic feature that sends test information to each slave circuits, receives a test signal from each slave in response, and displays the result on the screen.  If acknowledgement is not received, the location number of the non-responsive slave is displayed.  
• If a slave circuit pulls the clock [SCL] or data [SDA] line to ground, the microprocessor cannot communicate with any of the slave circuits.  In the event such a condition occurs, the power LED will flash at a rate of [1] per second.  Similarly, in the event of a protective shut down,  it will flash Twice a second.  The type of condition can be easly determined by the frequency of flashes.
