Basic Troubleshooting StepsBasic Troubleshooting Steps

Define, Localize, Isolate and Correct

•Define Look at the symptom carefully and determine what circuits could be causing the failure. Use your senses Sight, Smell, Touch and Hearing. Look for burned parts and check for possible overheated components. Capacitors will sometimes leak dielectric material and give off a distinct odor Frequency of power supplies will change with the load or listen forand give off a distinct odor. Frequency of power supplies will change with the load, or listen for relay closing etc. Observation of the front Power LED may give some clues.

•Localize After carefully checking the symptom and determining the circuits to be checked and after giving a thorough examination using your senses the first check shouldchecked and after giving a thorough examination using your senses the first check should always be the DC Supply Voltages to those circuits under test. Always confirm the supplies are not only the proper level but be sure they are noise free. If the supplies are missing check the resistance for possible short circuits.

•Isolate To further isolate the failure, check for the proper waveforms with the Oscilloscope to make a final determination of the failure. Look for correct Amplitude Phasing and Timing of the signals also check for the proper Duty Cycle of the signals. Sometimes “glitches” or “road bumps” will be an indication of an imminent failureglitches or road bumps will be an indication of an imminent failure.

•Correct The final step is to correct the problem. Be careful of ESD and make sure to check the DC Supplies for proper levels. Make all necessary adjustments and lastly always perform a Safety AC Leakage Test before returning the product back to the Customer

Note 1: Glasses can operate using the USB connector plugged in if batteries are not charged.Note 2: Don’t forget to try L/R select on the Remote before proceeding.Red Power LED should stay on solid for about 3 sec. then go off. When power button is pressed for Power Off, the LED will blink 3 times.A simple test is to hold the glasses about 1 ft. in front of you towards a white sheet of paper. The glasses should still be able to see the 3D Emitter signal from the TV while playing a 3D movie. If the glasses sync up the paper will appear as looking through normal sun glasses, if not synced, the paper will appear amber in color.

Don’t forget to check the “Type” of signal coming in to the TV and make sure it was selected on the first screen if not automatically selected.

Don’t forget to try swapping the L/R selection by pressing the “3D Setting button” on the remote control. (Blue Button in the Special Function Buttons)

Eye Tiredness InformationEye Tiredness Information

Why your eyes get tired while you’re seeing 3D images :• The color clarity and resolution of 3D images are lower than those of 2D.• 3D images deliver strong effects. Viewing “popping out” images, which is distorted, for a long time

makes you more tired. • Accommodation and convergence (Your both eyes focus a single point)• 3D presentation with glasses displays unnatural images due to no time difference during eye

3DC safety guidelines for distribution of 3D displays suitable for human eyes were made at the 3D Consortium 2006

3D presentation with glasses displays unnatural images due to no time difference during eye movements.

at the 3D Consortium 2006

• It is recommended to see 3D images within a distance of 2m. • The brain is not able to adjust the focus when you are more

than 2m away from the TV.• Customers don’t have the condition for seeing a display

within 2m, below warning sentence should be noticeable.

If it is impossible for customer to view 3D image displayed on the screen 2m away from the display,displayed on the screen 2m away from the display, keep in mind that the convergence angle should not exceed 2 degrees.

• For example, when you see the display 1m away from the TV, th di t f 3D i i t h ld b ithi

The brain gets confused because of the distance difference between the

actual image and the popping up image


the distance of any 3D image popping out should be within 38cm.

((LED BACKLIGHTS) LED BACKLIGHTS) AND INVERTER SECTIONAND INVERTER SECTIONIn this model the Inverter is part of the SMPS. It receives 5.2V (5.07V) from the SMPS Q702 on P702 pin 8 The Inverter On (DRV_ON) command arriving on P702 pin 6 starts the Inverter drive signals, p ( _ ) g p g ,(240Hz).P-DIM is delivered from the Main board through the SMPS to the Inverter on P702 pin 2.The Inverter is responsible for delivering B+ (approx. 142V) to each of the 12 LED Blocks. This is accomplished by D245 on the SMPS and filtered by C246 and C247

The Inverters must also deliver grounding pulses (Drive Signals) to each of the 12 LED Blocks. This is accomplished by the 12 switching components Q401 through Q412.

P204 drives V1a, V1b V1c and V2a, V2b V2c. P205 drives V3a, V3b V3c and V4a, V4b V4c.

PWM-DIM1 performs Global dimming, All blocks are controlled equally.Local Dimming (Each block is controlled independently) is accomplished by the SIN (Local Dimming Signal) sent from the Main board to the SMPS and arriving at the inverter on P702 pin

After the max. threshold is established by the Customer’s Menu, the DC Level of P-DIM is manipulated by:

Overall Contrast RatioMonitored by the BCM or Mstar Video Processor.

As the overall brightness of the video content decreases, so does P-DIM voltage.

If the Intelligent Sensor is utilized, it too manipulates P-DIM. As the overall room light decreases in intensity, P-DIM

decreases. This data represents nearly 5000 steps in room light monitoring. It is routed from the Front IR board through

FRONT (IR, INTELLIGENT SENSOR and MOVING LED) SECTIONFRONT (IR, INTELLIGENT SENSOR and MOVING LED) SECTION

The Intelligent Sensor and IR board (located on the bottom left as viewed from the rear) contains the IR (Infrared Remote Sensor) and the Intelligent Sensor. This board also connects with the Soft Touch Key Board and the Center LG Logo board. The Center LG Logo lights after power on and the picture appears. Then dims down in about 2 seconds. At power off, it does the reverse. It will remain on when the set is on if set up in the Customer’s Menu.

The IR board receives it operating B+ via J1 pin 6 (STBY 3.5V) 3.5V in STBY and 3.31V in Run.

The IR (Infrared) remote receiver can be measured (1.57V in STBY) at pin 9 of connector J1 or P8200 on the Main board in Stand-By. During run pin 9 reads (1.52V).

The IR pulses (1.6V p/p) J1 pin 9 are sent to P8200 on the Main board and on to the Microprocessor (IC8101) via pin 16.

The Intelligent Sensor communicates with the Micro/Video Processor IC900 BCM Chip via clock and data lines SCL1 and SDA1 arriving on connector J1 from P8200 pins 1 and 2 on the Main board.

The Front Power LEDs are controlled by these same Clock and Data lines which communicate with the LED Driver IC on the IR board.

The Key board is routed to the IR board via J2 and output on J1 Key 1 and Key 2 lines, • Key 1 pin 4 (3.31V)• Key 2 pin 5 (3.29V)Arriving at P8200 pins 4 and 5 on the Main Board then to the Microprocessor 25 and 26 lines.
