Alignment and Adjustments

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.

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.

4-2 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 colorbar 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 32 KV under any conditions.

Alignment and Adjustments

4-4 Dynamic Focus Adjustment

1.A dynamic focus adjustment should be done after replacing the CRT PCB, FBT or CRT.

2. Input a crosshatch pattern.

3.Enter “ STANDARD “ in video mode.

4.Turn the Dynamic focus VR fully clockwise (maximum).( )

5.Turn the Static focus VR fully counterclockwise (maximum).( )

6.Slowly turn the static focus VR counterclockwise. Adjust until the vertical line in the middle of the screen has maximum clarity.( )

7.Slowly turn the dynamic focus VR (clockwise) and adjust the 3rd horizontal line for maximum clarity.( )

4-5 SCREEN Adjustment

1.Input Toshiba Pattern

2.Enter “Service Mode”.(Refer to “Service Mode”)

3.Select “G2-Adjust”.

4.Set the values as below.

	29 Inch		21 Inch
IBRM	= 220	IBRM	= 220
WDRV = 35		WDRV = 35
CDL	= 220	CDL	= 165
COLR G B = 150 150 150		COL	= 70

Alignment and Adjustments

5.Turn the SCREEN VR until “MRCR G B” and “MRWDG” are green and those value are about 100. (The incorrect SCREEN Voltage may result that “MRCR G B” and “MRWDG” should be red)

Note 1. When you do not have Toshiba Pattern, follow this method.

1.Set the TV on the condition that AV mode no signal(black)

2.Enter the “Menu” and set the mode to blue screen off.

3.Enter the “Service Mode”.

4.Select “ G2-Adjust”.

5.Set the values as below.

IBRM	= 220
WDRV = 35
CDL	= 220

COLR G B = 150 150 150

6.Turn the SCREEN VR until the value of “ MRCR G B” is about 120. Do not mind that the “OSD” Color is red.

After completing G2-Adjust, follow this procedure.

Enter the “Video Adjust 1”.

Choose any item in menu. (ex. Select “Red Cutoff”)

Change the value of item you select, and recover the value.

For example, when the value of “Red Cutoff” is 127, change the value to 128 and restore the value to 127.

If you do not follow this procedure, the picture may be abnormal.

For example, when the TV set is on, the picture becames brighter gradually.

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

■Equipment : Color-Analyzer (CA-100)

■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”.

-Adjust “Sub Contrast” so that Y (luminance) becomes 40 ft ± 3.

-Use “Red Drive” and “ Blue Drive” to adjust High-Light (x : 290, y : 300)

-Adjust “Sub Bright” so that Y (luminance) becomes 1.3ft ± 0.3.

-Use “Red Cutoff” and “Blue Cutoff” to adjust Low-Light (x : 290, y : 300).

7.Adjust CA-100 so that the final adjustment value can be fixed.

8.Use the Channel Up/Down (▲/▼) buttons to move the cursor on the adjustment modes.

9.Use the Volume +/- buttons to change the adjustment value.
