SERVICE ADJUSTMENTS
Please notice the following before alignment and equipment
1. Don’t short any two soldering points, which should not be shorted and don’t touch any
components, which should not be touched.
2. Please pull out plug before equipment.
3. For safety reasons, all components equipped or replaced should be identical with BOM.
4. Must be warm up for 30 minutes or more and degauss CRT thoroughly with demagnetizer before
alignment.
The data of EEPROM must be stored before the adjustment for main chassis and EEPROM must be
corrected by the correct file 3Y03 ROM CORRECT.hex to avoid signal of CH6 weaken. R.bias,
G.bias, B.bias, R.drv, G.drv, B.drv should be set to proper values. Sub_bright is set to 63 usually.
Tools and equipments for adjustment
1. Small (-) screwdriver
2. Screwdriver without inductance
3. Pattern generator
4. DC Regulated power supply
5. Digital voltmeter
6. Sweep signal generator
7. 20MHz 2-Channel oscilloscope

covers on white signal.
3. Go to factory mode MENU2. Obtain GREY signal X=281 and y=311 by adjusting R-CUT and B-
cut. Obtain white signal X=281 and y=311 adjusting R-DRV and B-DRV. Obtain both X=281 and
Y=311 by adjusting the two status repeatedly.
Sub_Bright adjustment
Receive the grey scale. Get into the menu5 of factory mode. Set SUBB.ADJ to 1. Then adjust the
SUB.BRI option to get a scale to be seen a little brightness (only two rows can be seen).
Vertical size and Pin Cushion adjustment
1. Receive monoscope pattern. Set TV standard status. Adjust V.size to obtain pictures vertical
redisplay ratio mode than 90% in factory mode MENU1.
2. Receive cross hatch pattern. Set TV standard status. Adjust V.LINE and V.SC to obtain picture
vertical pin cushion a good status in factory mode MENU1.
3. Receive cross hatch pattern. Set TV standard status. In factory mode MENU1 adjust V.POS to
obtain pictures vertical center at the center of CRT screen.
Horizontal Center adjustment and horizontal position of OSD adjustment
1. Receive monoscope PATTERN. Set TV standard status. Adjust H.PHASE in menu 1. to obtain

2. Receive pure white signal in AV status and set the TV receiver dynamic.
3. Go to factory mode MENU2. After write down the values of R-BIAS and B-BIAS, set the values
of R-BIAS and B-BIAS zero.
4. Loosen the clamp screw of the deflection yoke and pull the deflection yoke towards color purity
magnetic loop.
5. Adjust color purity magnetic loop to make the green area at the center of CRT screen.
6. Slowly push the deflection yoke toward the front of CRT and set it where a uniform green field is
obtained. Tighten the clamp screw of the deflection yoke.
7. Restore the value of R-BIAS, G-BIAS and B-BIAS.
