4-1 Preadjustment

4-1-1 Factory Mode

1.Do not attempt these adjustments in the Video Mode.

2.The Factory Mode adjustments are necessary when either the EEPROM (IC902) or the CRT is replaced.

3.Do not tamper with the “Adjustment” screen of the Factory Mode menu. This screen is intended only for factory use.

4-1-3 When CRT Is Replaced

1.Make the following adjustments AFTER setting up after setting up purity and convergence :

White Balance Sub-Brightness Vertical Center Vertical Size Horizontal Size

Fail Safe (This adjustment must be the last step).

4-1-2 When EEPROM (IC902) Is Replaced

1.When IC902 is replaced all adjustment data revert to initial values. It is necessary to re-program this data.

2.After IC902 is replaced, warm up the TV for 10 seconds.

2.If the EEPROM or CRT is replaced, set PVA to 45 (factory mode) and set SC as follows.

14, 16 inch : 0 20 inch : 10

21 inch : 12

4-2 Factory/Service Mode

4-2-1 Procedure for the “Adjustment” Mode

1.This mode uses the standard remote control. The Service Mode is activated by entering the following remote-control sequence :

(1)SLEEP→FACTORY.

(2)STAND-BY→ DISPLAY→ P.STD→ MUTE →POWER ON.

2.The “SERVICE (FACTORY)” message will be displayed. The Service Mode has four components: Adjustment, Test Pattern, Option Bytes and Reset.

3.Access the Adjustment Mode by pressing the “VOLUME” keys ( Up or Down). The adjustment parameters are listed in the accompanying table, and selected by pressing the CHANNEL keys (▲ ,▼).

4. Selection sequences for the all system:

DOWN or UP key: AGC>VCO>SBT>SCT>SCR>SC>RG>GG> BG>CDL>BLU>PSL>PVS>PVA>PHS>NSR> STT

5.The VOLUME keys increase or decrease the adjustment values (stored in the

non-volatile memory) when Adjustment Mode is cancelled.

6.Cancel the Adjustment Mode by re-pressing the “FACTORY” or “Power OFF” keys.

4-2-3 Test Pattern (Aging Mode)

1.This mode can be used during servicing, or for confirming that the convergence and purity adjustments are correct.

2.Access the Test Pattern parameters by pressing a CHANNEL keys (▲ ,▼) while the Service Mode is on. The cursor will move to the test pattern. Press the VOLUME keys. On-screen display:

• WHITE NON -TTX MICOM ONLY

	• AGING
	• AGING			TTX MICOM
				TTX MICOM
	3. AGING Mode (Reference Only)

This pattern is used for pre-heating the CRT during manufacturing

—it is accessed in the factory by twice pressing the “SLEEP → FACTORY→FACTORY “ key, then white pattern will be displayed.

Even if the TV power is cut off, the Aging Mode is not cancelled, The aging mode is cancelled by repressing the “FACTORY” key or pressing the local “CH UP/DOWN” keys.

4-2-4 Option Bytes

In the Service Mode, various can be selected via the Option Bytes (8 bits each). Example:
