In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

SONY KDL-32D3000 SERVICE MODE AND LED ERROR CODES

SONY KDL-32D3000 SERVICE MODE AND LED ERROR CODES


SONY KDL-32D3000

SERVICE MODE AND LED ERROR CODES 

WAX3 SELF DIAGNOSTIC SOFTWARE

The identification of errors within the WAX3 chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In the event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous flashing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device number will be displayed through the LED (Series of flashes which must be counted).
Number of Standby LED (Red) Blinking
Monitoring Items
2
Main power supply voltage error
3
DC_ALERT1
4
DC_ALERT2
5
DC_ALERT3
6
Backlight error
7 *2
Internal temperature error
8
Audio error
9
Fan error (HFR model only)
10
Digital FE error
11
Trident error
12
HFR error *1
13
Balancer error

Note *1: It is judged as HFR Error when Safety Shutdown is activated due to either of FRC ACK error, 1.5V error, 2.5V/3.3V error, or Panel 12V error.
Note *2: The number of LED-blinking times for Internal temperature error is also used for BH-board temperature error: these two errors are distinguished from whether TV Shutdown is involved or not.
How to enter Service Mode
Service adjustments to this model can be performed using the supplied remote Commander RM-ED009.
1. Turn on the power to the TV set and enter into the stand-by mode.
2. Press the following sequence of buttons on the Remote Commander.
ON SCREEN DISPLAY (i) > CHANNEL 5 > VOLUME + > POWER ON
3. The menu will then appear on the screen.
4. Move to the relevant command using the up or down arrow Mbuttons on the remote commander.
5. Press the right arrow button to enter into the required menu item.
6. Press the ‘Menu’ button on the remote commander to quit the Service Mode when all adjustments have been completed.
Note : After carrying out the service adjustments, to prevent the customer accessing the ‘Service Menu’ switch the TV set OFF and then ON
Gamma Adjustment
The following adjustments are done via ECS.
Note: Before Gamma adjustment can begin the set needs 20 minutes aging with an ambient temperature between 22 to 28 degrees centigrade.
Preparation before Gamma Adjustment
1. Set SREG_BL_MANU = 1.
2. Set SREG_MUTE_DISPLAY = 0.
3. Set SREG_BL_GAIN = 255.
4. Send ECS command OSD_OFF.
5. Send ECS command CSC_BYPASS_INIT_SET.
6. Wait for successful retrieval.
7. Set SREG_BRIGHT = 100(max).
8. Set SREG_ECO_MODE = 0(Standard).
9. Set SREG_TEST_G_LEVEL = 255.
10. Set SREG_GAMMA_EN = 0(OFF).
11. Measure ‘maximum brightness’ and ‘panel peak white color’ and record x, y and Y data.
12. Confirm this data
[Case A] if y => 0.298, check that the brightness is equal to or greater than Spec A.
Set and save WB register A as follows :-
WB_GAM_G01 = 124
WB_GAM_G02 = 120
WB_GAM_G03 = 116
WB_GAM_G04 = 118
WB_GAM_G05 = 112
WB_GAM_G06 = 109
WB_GAM_G07 = 108
[Case B] if 0.293 =< Y < 0.298, check that the brightness is equal to or greater than Spec B.
Set and save WB register B as follows :-
WB_GAM_G01 = 126
WB_GAM_G02 = 124
WB_GAM_G03 = 122
WB_GAM_G04 = 123
WB_GAM_G05 = 120
WB_GAM_G06 = 119
WB_GAM_G07 = 118
[Case C] if y < 0.293, check that the brightness is equal to or greater than Spec C.
Set and save WB register C as follows :-
WB_GAM_G01 = 128
WB_GAM_G02 = 128
WB_GAM_G03 = 128
WB_GAM_G04 = 128
WB_GAM_G05 = 128
WB_GAM_G06 = 128
WB_GAM_G07 = 128
· If the brightness is lower than the spec consider the panel as no good.
