Precautions 1. Precautions Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays. 1-1 Safety Precautions 1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields. 2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices, including: nonmetallic control knobs and compartment covers. 3.
Precautions 1-1 Safety Precautions (Continued) 9. High voltage is maintained within specified limits by close-tolerance, safety-related components and adjustments. If the high voltage exceeds the specified limits, check each of the special components. 10. Design Alteration Warning: Never alter or add to the mechanical or electrical design of this unit. Example: Do not add auxiliary audio or video connectors. Such alterations might create a safety hazard.
Precautions 1-2 Servicing Precautions Warning1: First read the “Safety Precautions” section of this manual. If some unforeseen circumstance creates a conflict between the servicing and safety precautions, always follow the safety precautions. Warning2: An electrolytic capacitor installed with the wrong polarity might explode. 1. Servicing precautions are printed on the cabinet. Follow them. 2.
Precautions 1-3 Precautions for Electrostatically Sensitive Devices (ESDs) 1. Some semiconductor (“solid state”) devices are easily damaged by static electricity. Such components are called Electrostatically Sensitive Devices (ESDs); examples include integrated circuits and some field-effect transistors. The following techniques will reduce the occurrence of component damage caused by static electricity. 2.

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. 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. 2. Observe the picture for good black and white details.
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. ❶ 3. Enter “ STANDARD “ in video mode. 4. Turn the Dynamic focus VR fully clockwise (maximum).(❶ ) ❷ 5. Turn the Static focus VR fully counterclockwise (maximum).(❷ ) 6. Slowly turn the static focus VR counterclockwise. Adjust until the vertical line in the middle of the screen has maximum clarity.(❶ ) 7.
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. 2. 3. 4. 5. Set the TV on the condition that AV mode no signal(black) Enter the “Menu” and set the mode to blue screen off. Enter the “Service Mode”. Select “ G2-Adjust”. Set the values as below.
Alignment and Adjustments 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.
Alignment and Adjustments 4-8 Factory Adjustment 4-8-1 Service Mode 1. To enter the “Service Mode”, Press the remote-control keys in this sequence : - If you do not have Factory remote-control PICTURE OFF Keys Number 1,8,2 MUTE PICTURE ON - If you have Factory remote-control PICTURE ON DISPLAY ( ) FACTORY 2. After the Service Mode is entered, the initial screen is as shown in the figure below.
