SHARP LC-150M2E LCD AV MONITOR– Adjustment Modes _ Circuit Diagram
AC adapter: UADP-0181CEZZ
DC power supply: 12 ± 0.5V
DC power supply: 12 ± 0.5V
After initialization of E2PROM the mode is changed to the
adjustment mode.
Procedure: Connect TP2007 and TP2008 to GND, and turn on the power.
The initialization of microcomputer is as follows.
AV position, DAC data, G/A data, and video chroma data adjustment values are taken as defaults.

Change to adjustment mode
* Short-circuit TP2007 to GND, and turn on the power.
** Or short-circuit TP2008 to GND, and turn on the power.
** Or holding down the [AV INPUT] key and [MENU] key, turn on the main power, and simultaneously press the (inspection process) [SELECT ▼] key and [VOL– ] key to change the mode to the adjustment mode.
* Short-circuit TP2007 to GND, and turn on the power.
** Or short-circuit TP2008 to GND, and turn on the power.
** Or holding down the [AV INPUT] key and [MENU] key, turn on the main power, and simultaneously press the (inspection process) [SELECT ▼] key and [VOL– ] key to change the mode to the adjustment mode.
The manual adjustment or adjustment through communication with the
automatic machine is performed.
Inspection mode
Holding down the [AV INPUT] key and [MENU] key, turn on the power.
Holding down the [AV INPUT] key and [MENU] key, turn on the power.
* In the ordinary menu select “PICTURE” with the [SELECT] key,
and decide with the [VOL] key. Then select “CONTRAST”, “TINT (only NTSC)”,
“COLOR”, “BLACK LEVEL”, “SHARPNESS”, “RED” , and “BLUE” with the [SELECT] key,
and decide with the [VOL] key. After that, adjust values with the [VOL] key.
* In the ordinary menu select “SOUND” with the [SELECT] key, and decide with the [VOL] key. Then, select “TREBLE”, “BASS”, and “BALANCE” with the [SELECT] key, and decide with the [VOL] key. After that adjust values with the [VOL] key.
* VOLUME, CONTRAST, TINT (only NTSC), COLOR, BLACK LEVEL, SHARPNESS, RED, BLUE, TREBLE, BASS, and BALANCE change sequentially.

Shipping setting mode
Holding down the [AV INPUT] key and [MENU] key, turn on the main power, and simultaneously press the (inspection process) [SELECT▲] key and [VOL+] key to change the mode to the adjustment mode.
User adjustment and other values are taken as defaults.
If AV1 is indicated as SETTING COMPLETE, setting has been completed.
