Technical Description

When viewing 3D contents in normal mode; the 3D glasses open its left shutter only while the left image is displayed and conversely open its right shutter only while the right image is displayed.

However, when viewing 3D contents in 3D/ 2D conversion mode; the 3D glasses open both its right and left shutters while the left image is displayed and on the other hand, close both its shutters while

the right image is displayed. Therefore users only watch the left image as 2D.

5. Lamp Error Detection

1. FunctionThis LCD colour TV set incorporates a Lamp error detection feature that automatically turns off the power for safety under abnormal lamp or lamp circuit conditions. If by any chance anything is wrong with the lamp or lamp circuit or if the lamp error detection feature is activated for some reason, the following will result.1) The power is interrupted in about 500ms after it is turned on.

(A central icon on the front of the TV flash on and off.: ON for 400ms and OFF for 1600ms.)2) If the above phenomenon 1) occurs 5 times, it becomes impossible to turn on the power.

(A central icon keep flashing on/off.)

2. Measures1) Set the lamp error detection to OFF

Enter the adjustment process mode, referring to 4. Entering and exiting the adjustment process mode.The adjustment process mode can ignore 5 times count, so If the above phenomenon 1) occurs 1~4 times, the lamp will go out.

If Lamp Error detection pin [4pin of PD: P9602/19pin of IC2001] is High by a trouble with the lamp and lamp circuit, it can boot-up by the adjustment process mode.Please execute Lamp Error detection off-mode.

While holding down the VOL (-) and CH ( UP) keys on the set at once, touch the power supply key on the set.After a central icon flash off, separate the fingers from key on the set.

Then, you can check the operation to see if the lamp and lamp circuit are in trouble.If you fail boot-up, retry the procedure.

STAND-BY ERROR LED BLINKING Table

LED flashing specification at the time of the error

Display method Refer to Table 1. LED that can be used are only one of the central icon (Emblem Unit).

This expresses the error situation by combining blinking at low speed and blinking at high speed. For this model, the blinking pattern displayed first is only a low-speed blinking.

This expresses a rough content of the error. For this model, details are displayed by a high-speed blinking by pushing remote control MENU key.

This expresses details of the error.Details are distinguished by the blinking frequency.

It doesnt return to the outline display again (blink at low speed) by pushing the MENU key (The toggle is not done).Please confirm MONITOR ERR CAUSE of the adjustment Process mode (1/24 page), when the error doesn't reproduce by having returned from the error.

The process of the upgrade is expressed by the brightness of point LED that smoothness changes. The upgrade completion is expressed by the LED brightness that changes in a staircase pattern.

For white balance adjustment, adjust the offset values on pages 11/24.

[Condition of the unit for inspection] : Modulated light (+16)AV MODE: DYNAMICActive Backlight: OFFOPC: OFFAsing Time: Min, 60 minute

[Input signal condition] : HDMI 1080i 15IRE (LO), 78IRE (HI)[Adjustment reference device] : Minolta CA-210[Adjustment procedure]1) Display the current adjustment status at R/G/B_GAIN (HI). (Page 11/24 of process adjustment)

The signal of 78IRE is input.2) Read the value of the luminance meter. x=0.272, y =0.2773) Change R_GAIN (HI)/ B_GAIN (HI) (Adjustment offset value) on page 11/24 of process adjustment so that the values of the luminance meter

approach x=0.272 and y =0.277.(Basically, G is not changed. If adjustment fails with R and B, change G. When G is lowered, the weaker of R or B must be fixed.)

4) Display the adjustment status of the current R/G/B_GAIN (LO).The signal of 15IRE is input.Change R_GAIN (LO)/ B_GAIN (LO) (adjustment offset value) on page 11/24 of process adjustment so that the values of the luminance meter approach x =0.272 and y = 0.277.

5) Both HI and LO are repeating the step from 1 to 4 until becoming an aim value.[Adjustment reference standard value]Adjustment spec +/- 0.002 Inspection spec +/- 0.004 (point LO)Adjustment spec +/- 0.001 Inspection spec +/- 0.002 (point HI)

6) After completing adjustments, set EEP SAVE (Page 24/24) to ON in the process menu to save the white balance adjustment value
