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 Adjustments 4-1-1 General Alignment Instructions Usually, a color TV needs only slight touch-up adjustment upon installation. Check the basic characteristics such as vertical size, horizontal size, and focus. Observe the picture and check for good black and white details. There must be no objectionable color shading: If color shading is present, demagnetize the receiver. If color shading persists, re-do purity and convergence adjustments. Note : 1.
Alignment and Adjustments 4-1-3 Screen Voltage Adjustment 1. Enter the Service Mode by pressing the remote control keys in the following sequence : Power Off Mute 1 8 2 Power On 2. Initialize all set data. 3. Input a Toshiba pattern. 4. Use an oscilloscope to identify RK, BK, GK. And then adjust FBT Screen VR so that the voltage of pedestal level doesn’t exceed 175V.
Alignment and Adjustments 4-1-5 When adjusting Screen Voltage and White Balance 1. Screen Voltage and White Balance are related each other. Make sure both adjustments are correct. 2. Adjust Screen Voltage before White Balance Adjustments. Make sure Screen Voltage is correct. 3. If White Balance has been readjusted, re-check Screen Voltage. 4. After adjustments are complete, check the following. - If spots appear on the screen after pressing the Power On/Off key, readjust Screen Voltage.
