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

PIF Adjustment (45.75MHz)
1. Tuner AGC connects to GND. Pattern generator outputs 45.75MHz IF. Signal (70db V) and
connects to SAW filter output terminal through a capacitor.
2. Connect digital voltmeter across C227. DC regulated power supply positive terminal output +14V
to C617.
3. Adjust L203 coil to obtain 3.6V Digital voltage meter reading.
Note: To cancel this adjustment, L203 can be adjusted before inserted to the chassis with a special
equipment.

3. Adjust the focus knob of FBT to get the clearest picture.
Screen voltage adjustment
1. Check the R.bias, G.bias, B.bias, R.drv, G.drv, B.drv and sub_bright. Go to factory mode MENU2
status according to 4-2-2. Usually G.bias should be same as the value of auto white balance
equipment. And SUB_BRIGHT is 63.
2. Set Cross_BW 3. Then the picture will be a white +. Cross_BW is in factory menu 3.
3. In menu 5, select SUBB.ADJ and set it to 1. Adjust the screen knob of FBT to get a faintness +.
4. Restore the SUBB.ADJ to 0 and CROSS.BW to 0.
White balance adjustment (Applied in factory)
1. Set TV AV status in custom mode (or other mode need for the adjustment). Receive black white
pattern.
2. Insert six-row-wire into CN002. Press adjustment keys and then go to automatic white balance
adjustment.
3. PIN DISCRIPTION OF CN002:
1●●SDA●●2●●SCL●●3●●GND●●4●●GND●●5●●SCL●●6●●SDA
4. After adjust well, pull out six-row-wire.
White balance adjustment (Applied when servicing)
1. Set TV AV status and receiv GREY SCAL.
2. The one sampling tube of CRT color analyzer (CA-100) covers on GREY signal and the another
covers on white signal.
3. Go to factory mode MENU2. Obtain GREY signal X=281 and y=311 by adjusting R-CUT and Bcut. 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
horizontal center at the center of CRT screen.
2. Adjust OSD.HPOS to get right display position.

Receive the RF CROSS-TALK signals but FM with BTSC. Enter into the factory mode. Set ADJ.
FREQ to 1 in 9852 AUTO.ADJ. wait 1 second. Quit factory menu after ADJUSTING change to 0.
Color purity adjustment
1. Before color purity adjustment, warm up the TV set over 15 minutes and fully degauss.
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.
Convergence adjustment
1. Receive a dotted pattern. Set the TV receiver dynamic.
2. Loose the convergence magnet clamper and align red with blue dots at the center of the screen by
rotating (R,B) static convergence magnets.
3. Align Red /Blue with green dots at the center of the screen by rotating (RB-G) static convergence
magnet.
4. Remove the DY wedges and slightly tilt the deflection yoke horizontally and vertically to obtain
the good overall convergence. Fix them after the good overall convergence got.
5. If purity error is found, follow PURITY ADJUSTMENT instructions.
