ADJUSTING PROCEDURE OF EACH SECTION

The best adjustment is made before shipping. If any position deviation is found or after part replace is performed, adjust as follows.

Preparation for adjustments

Use the dedicated AC adaptor or stable DC power supply. LC-13/15S1E AC adaptor: UADP-A043WJPZ DC power supply: 12V 5.0A

1.Adjusting procedure

• Checker adjustment Power ON (Adjustment processing mode) → +B adjustment → Counter bias adjustment → TAMP (Contrast) adjustment → White balance adjustment

2.Entering the adjustment processing mode

There are the following two methods.

• Setting the pin (81)(KEY4) or pin (82)(KEY5) of IC2001 (microprocessor) to GND, turn on the power.

• A "POWER" ke y is made on with pushing an "TV/VIDEO" and "MENU" k e ys at the same time .(K of the inspection

process mode is displayed b y the upper left of the image plane.) → Ne xt, "CH (Ù)" and "VOL (–)" ke ys are pushed

at the same time.(It becomes the image plane of the adjustment process mode.).....When it is canceled, it is made

to turn it off.(Even off in the "MAIN POWER" key, off with R/C are good.)

3.Key operation in the adjustment process mode

• The receiving channel UP/DOWN is performed with the "CH (ù)/(Ù)" keys. One push ... The UP/DOWN tuning is performed per channel. Continuous push ... The UP/DOWN search is performed until a next receivable station is found.

• V arious adjustments The adjustment is performed for each item by the "MENU", "Menu cursor", "CH (ù)/(Ù)" or "VOL (+)/(–)" keys (LCD TV set and remote control).

• Adjustment item is chosen with the Menu cursor upward/downward keys.

• The adjustment item makes a toggle operation with the "MENU" key input. (Next item)

If the "MENU" key is input while the bottom item is selected, it moves to the top item on the next page.

• Press the auto preset button on the remote controller in the adjustment process mode, and the top item of the next page will show up regardless of which item appears now. Page 1 → Page 2 → ... → Page 66 → Page 1

• Press the manual memory button on the remote controller in the adjustment process mode, and the top item of the same page will show up.

• UP/DOWN of each adjustment vale selected is performed with the VOL (+)/(–) keys input.

4.Initialization

When the microprocessor (IC2001) or the EEPROM (IC2007, IC2009) has been replaced or when the EEPROM has been initialized, readjust the each adjustments. 4-1. Connect the pins (81) and (82) of IC2001 (microprocessor) to GND, and turn on the power. 4-2. Check that the model name is (A661). 4-3. Select the inch size (13) : (LC-13S1E) and (15) : (LC-15S1E). 4-4. LED changes green from red after setting finish and about 15 seconds, initialization is completed, and it

becomes adjustment mode.

4-5. Writing the model-by-model data

For the Ver.1.00A microprocessor, get it initialized first and then make the settings, listed below, on it. (The microprocessor version is indicated at the bottom of Adjustment Process Page 1.)

5.Adjustment

5-1. +B adjustment...Page 1 +B-ADJ

Adjust the voltage of the pin (4) of P1900 to 5.00 ±0.02V with R3714. Note: Since 5.0V is a reference voltage of all power voltage, adjust it precisely.

5-2. Counter-bias adjustment

Vary the "COM BIAS" setting on Page 2 of the adjustment process mode so that the contrast be sharpest (black looks most sinking).

5-3. TAMP adjustment

1) Receive the upper left of 75% white half colour bar signal.

2) See if the "Y" reading on page 2 of the adjustment process mode is somewhere following. If not, make the "PAL TAMP" adjustment to get the "Y" reading in the range of AE thru BD.

3) If the adjustment of "PAL TAMP" is executed, write its adjustment value to the "SECAM TAMP" manually.

6. Factory Setting

6-1. Perform a factory setting after completing all adjustments. 6-2. A "POWER" keys is made on with pushing an "TV/VIDEO" and "MENU" keys at the same time. 6-3. "K" of the inspection process mode is displayed on the screen upper left. 6-4. CH (ù) and VOL (+) keys are pushed about 2 seconds at the same time. 6-5. Release keys, if "E" is displayed on the screen upper left and "COMPLETE" is displayed on the bottom of it. 6-6. After a while, a power will be in a standby mode and a setup will be finished. Note: "First installation" serves on "Deutsch".

7. Lamp error detection

7-1. Functional description

This LCD colour television has a function (lamp error detection) to be turned OFF automatically for safety when the lamp or lamp circuit is abnormal. If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed, the followings occur. 1 The main unit of television is turned OFF 5 seconds after it is turned ON. (The power LED on the front

side of TV turns from green to red.)

2 If the situation 1 happens 5 times sequentially, television can not be turned ON. (The power LED remains

red.)

7-2. Countermeasures 7-2-1.Check when turning OFF the lamp error detection

When television is turned OFF by the lamp error detection mentioned above, it enters the adjustment process with the power LED red. Entering the adjustment process turns OFF the error detection and turns ON TV. This enables the operation check to detect errors in the lamp or lamp circuit. Check whether "ERROR NO RESET" on line 3, page 1 of the adjustment process is 1 or more. If it is 1 or more, it indicates the lamp error detection was executed.

7-2-2.Resetting of the lamp error count

After confirming that the lamp or lamp circuit is normal, reset the lamp error count. Select "ERROR NO RESET" on line 3, page 1 of the adjustment process and set the number to 0 using the volume button.

Afterwards, perform the operation check to confirm that the lamp error detection does not function.
