3. Alignment & Adjustment
3-1 Service Instruction
1. General Adjustment :
In general, a color TV can provide ideal visual quality by adjusting the basic settings such as the vertical size, horizontal size,
focus, etc.
Display a black and white picture on the screen to check if the picture is clearly displayed.
If there are some 'spotted' points on the screen when displaying a black and white picture, degauss the screen using the
degauss coil. If the spotted points remain, re-adjust the purity and the convergence.
This completes the basic performance examination.
Notice.
■ These adjustments and the check list are only applied to S16D chassis-applied models.
■ Only use 230V for the measurement set. It is recommended using an insulation transformer when supplying power to
the set so as to prevent shock to the set or to yourself.
■ These adjustment specifications have been created on the basis of the domestic S16D chassis-applied remote control
model. Some of the contents may be changed subject to the sales location and the product specifications.
※When replacing the Module Service Instruction
1. When replacing the MAIN Board : Tilt adjustment, Focus adjustment, Screen voltage, W/B adjustment are all required. Since
the settings including the Channel information,Deflection, etc. are saved to the EEPROM,
recogfigure these settings when replacing the MAIN Board.
The notation of the software information : T-HITPEU-1000 refer to "HITCH BASIC MODELEUROPE.ver.1000"
Since the settings including the Channel information, Deflection, etc. are
saved to the EEPROM, recogfigure these settings when replacing the MAIN Board.
2. When replacing the CRTAss'y : No adjustments required
3. When replacing the front panel Master Power switch : No adjustments required
4. When replacing the Side AV Ass'y : No adjustments required
5. When replacing the PIP Module : No adjustments required
6. When replacing the Control Ass'y : No adjustments required
7. When replacing the PFC Ass'y : No adjustments required
1. To enter Service Mode, press the keys on the remote control according to the following sequence. (in Stand-by status)
