Short jumper in main PCB i.e V511 AND V512 jumpers.
This will put the television receiver into service mode and the text TEST will appear on the TV screen.
Once in service mode, pressing of 0,1,2,6,7,8,and 9 buttons on the remote handset will display a lock icon on the screen.
Enter the code 200528 on the remote handset.
Now you can open the required service menu by pressing the number associated with that menu item. For example to open service menu 8, press the numeric key 8 on the remote handset.
SERVICE MODE CONTROLS
Use the PR+/ PR- keys to select an item parameter in the service mode.
Once an tem parameter is selected use VOL+/ VOL- button change the value of the selected item.
CANCELLATION OF SERVICE MODE
To come out of the service mode, switch off and then again turn back on the television set.
When the tv set is on press the following buttons, in the given order, on the remote handset.
press > 2>0>0>3
This will put the TV set into service mode and service mode and service mode option are displayed on the screen.
SERVICE MODE CONTROLS
Use the CH+/ CH- key to select an item / parameter in the service mode
Once an item / parameter is selected use VOL+ /VOL- button change the value of the selected item.
Press (8) for white balance
Child lock password value is 1227

CIRCUIT DIAGRAM OF PIR SENSOR RELAY DRIVING CKT
IMAGE OF PARTS MOUNTED PBC
Here 7812 for regulating for 12v dc from source voltage. Then supply to pir sesor ( which detect human motivity ) . Sensor has 3 terminal +B , GND, O/P . The O/P voltage is 3.3v . The 3.3v is given to transistor base trough a resistor 2K7 ohems . Transistor emitter is GND. The collector of Transistor is connect to relay and another point of relay gets 12v from ckt.
So when sensor see a Human activity he out 3.3v and transistor get on the relay.
You can use this so many purpose like automatic door open close, Alarm, or many more.
In this sensor have two preset first is distance adjustment and second is delay time adjustment
