4. Alignment and Adjustments
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). 2. If the EEPROM or CRT is replaced, set SC and PVA to 10 and 45 (Factory mode). SC : 14, 16 Inch : 0 20, 21 Inch : 10
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.
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) SLEEPFACTORY. (2) STAND-BYP.STDHELPSLEEP 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 (v ,w). 4. Selection sequences for the PAL system: DOWN or UP key: AGC>VCO>SBT>SCT>SCR>SC>RG> GG>BG>CDL>BLU>PSL>PVS>PVA>PHS 5. Selection sequences for the NTSC system: DOWN or UP key: AGC>VCO>SBT>SCT>SCR>SC>RG> GG>BG>CDL>BLU>NSL>NVS>NVA>NHS 6. The VOLUME keys increase or decrease the adjustment values, (stored in the non-volatile memory when Adjustment Mode is cancelled). 7. Cancel the Adjustment Mode by re-pressing the "FACTORY" or Power OFF.

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 (v ,w) while the Service Mode is on. The cursor will move to the test pattern. Press the VOLUME keys. On-screen display: ° ·RED ° ·GREEN ° ·BLUE ° ·AGING
NON -TTX MICOM ONLY 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 FACTORYFACTORY " 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" key. The patterns are displayed at 5 sec intervals : NON-TTX Micom only.
4-2-4 Option Bytes
In the Service Mode, various can be selected via the Option Bytes (8 bits each). Example:

4-3 Other Adjustments
4-3-1 General
1. Usually, a color TV needs only slight touchup adjustment upon installation. Check the basic characteristics such as height, horizontal and vertical sync and focus. 2. The picture should have good black and white details. There should be no objectionable color shading; if color shading is present, perform the purity and convergence adjustments described below. 3. Use the specified test equipment or its equivalent. 4. Correct impedance matching is essential. 5. Avoid overload. Excessive signal from a sweep generator might overload the front-end of the TV. When inserting signal markers, do not allow the marker generator to distort test results. 6. Connect the TV only to an AC power source with voltage and frequency as specified on the backcover nameplate. 7. Do not attempt to connect or disconnect any wires while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts. 8. To protect against shock hazard, use an isolation transformer.
4-3-2 Automatic Degaussing
A degaussing coil is mounted around the picture tube, so that external degaussing after moving the TV should be unnecessary. But the receiver must be properly degaussed upon installation. The degaussing coil operates for about 1 second after the power is switched ON. If the set has been moved or turned in a different direction, disconnect its AC power for at least 10 minutes. If the chassis or parts of the cabinet become magnetized, poor color purity will result. If this happens, use an external degaussing coil. Slowly move the degaussing coil around the faceplate of the picture tube and the sides and front of the receiver. Slowly withdraw the coil to a distance of about 6 feet before removing power.

4-3-3 High Voltage Check
CAUTION: There is no high voltage adjustment on this chassis. The B+ power supply must be set to +125 volts (Full color bar input and normal picture level).
4-3-6 Purity Adjustment
1. Warm up the receiver for at least 20 minutes. 2. Plug in the CRT deflection yoke and tighten the clamp screw. 3. Plug the convergence yoke into the CRT and set in as shown in Fig. 4-2. 4. Input a black and white signal. 5. Fully demagnetize the receive by applying an external degaussing coil. 6. Turn the CONTRAST and BRIGHTNESS controls to maximum. 7. Loosen the clamp screw holding the yoke. Slide the yoke backward or forward to provide vertical green belt. (Fig. 4-3). 8. Tighten the convergence yoke. 9. Slowly move the deflection yoke forward, and adjust for the best overall green screen. 10. Temporarily tighten the deflection yoke. 11. Produce blue and red rasters by adjusting the low-light controls. Check for good purity in each field. 12. Tighten the deflection yoke.
1. Connect a digital voltmeter to the second anode of the picture tube. 2. Turn on the TV. Set the Brightness and Contrast controls to minimum (zero beam current). 3. The high voltage should not exceed 27.5KV. 4. Adjust the Brightness and contrast controls to both extremes. Ensure that the high voltage does not exceed 27.5KV under any conditions.
4-3-4 FOCUS Adjustment
1. Input a black and white signal. 2. Adjust the tuning control for the clearest picture. 3. Adjust the FOCUS control for well defined scanning lines in the center area of the screen.
4-3-5 Cathode Voltage Adjustment (Screen Adjustment)
1. Connect CRT socket pin GK to an oscilloscope probe. 2. Input a gray scale pattern. (Use a pattern generator, PM5518) 3. Use the P mode key (on the remote control) for the STANDARD picture. 4. Adjust the Screen VR (on the FBT) so that the _ voltage on the oscilloscope becomes 130+2.5V (See Fig. 4-1).

4-3-8 Center Convergence Adjustment
1. Warm up the receiver for at least 20 minutes. 2. Adjust the two tabs of the 4 pole magnets to change the angle between them. Superimpose the red and blue vertical lines in the center area of the screen. 3. Adjust the Brightness and Contrast controls for a well defined picture. 4. Adjust the two-tab pairs of the 4 pole magnets, and change the angle between them. Superimpose the red and the blue vertical lines in the center area of the screen. 5. Turn the both tabs at the same time, keeping the angle constant, and superimpose the red and blue horizontal line in the center of the screen. 6. Adjust the two-tab pairs of the 6-pole magnets to superimpose the red and blue line onto the green. (Changing the angle affects the vertical lines, and rotating both magnets affects the horizontal lines.) 7. Repeat adjustments 2~6, if necessary. 8. Since the 4-pole magnets and 6-pole magnets interact, the dot movement is complex (Fig. 4-5).
