4. Alignment and Adjustments
4-1 General Alignment Instructions
1. Usually, a color TV-VCR needs only slight touch-up adjustment upon installation. Check the basic characteristics such as height, horizontal and vertical sync and focus. 2. Observe the picture for good black and white details. There should be objectionable color shading; if color shading is present, demagnetize, perform purity and convergence adjustments described below. 3. Use the specified test equipment or its equivalent. 4. Correct impedance matching is essential. 8. To protect against shock hazard, use an isolation transformer. 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.
4-2 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 is moved or turned in a different direction, the power should be OFF 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 turning power OFF. If color shading persists, perform the following Color purity and Convergence adjustments.
4-3 High Voltage Check
CAUTION : There is no high voltage adjustment on this chassis. The B+ power supply should be +135 volts (with full color- bar input and normal picture level).
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. Adjust the Brightness and contrast controls to both extremes. Ensure that the high voltage does not exceed 30 KV under any conditions.

4-4 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.
4-5 SCREEN Adjustment
1. Input Toshiba Pattern 2. Enter "Service Mode".(Refer to "4-8-1 Service Mode") 3. Select "G2-Adjust". 4. Set the values as below. Table 1. Screen Adjustment Table COLR G B (Smallest Value) 100 100 100 100 150 65 65 65 120 150 Noraml CIS

4-6 E2PROM (IC902) Replacement
1. When IC902 is replaced, all adjustment data revert to the initial values. So, all adjustment values when servicing should be readjusted. 2. After IC902 is replaced, connect the AC power supply cord. 3. Turn the power switch ON. 4. In stand-by, warm up the TV for at least 10 seconds. 5. Power on the TV.
4-7 White Balance Adjustment
s Equipment : Color-Analyzer (CA-100) s Input Signal : Pattern signal (Toshiba pattern) 1. Select STANDARD from the menu. 2. Input an 100% White pattern. 3. Enter the "Service Mode". (Refer to "4-8 Service Mode") 4. Warm up the TV set at least for 30 minutes. 5. Input a Toshiba pattern signal. 6. Enter the "Video Adjust1". (Refer to table 2.) - Adjust "Sub Contrast" so that Y (luminance) becomes 65 ft ± 3. - Use "Red Drive" and " Blue Drive" to adjust High-Light (x : 265, y : 265) - Adjust "Sub Bright" so that Y (luminance) becomes 1.2ft ± 0.3. - Use "Red Cutoff" and "Blue Cutoff" to adjust Low-Light (x : 265, y : 265). 7. Adjust CA-100 so that the final adjustment value can be fixed. 8. Use the Channel Up/Down (v/w) buttons to move the cursor on the adjustment modes. 9. Use the Volume +/- buttons to change the adjustment value.
