TU-PT700U 2 Safety Precautions 2.1. General Guidelines 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
TU-PT700U 3 Prevention of Electro Static Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor "chip"...

Measurement Instrument Remarks 1. Oscilloscope Picture menu: VIVID Picture pattern: Studio color bar 2. Alignment equipment Probe: The signal should be terminated by 75W, ±1% resistor.
TU-PT700U 9 Self-check Function When symptoms like “the power fails sometimes” or “sometimes there is no picture and/or sound” can not be confirmed at the time of servicing, the self-check function can be used to confirm the occurrence and to find the defective circuit.
TU-PT700U 9.2. Power LED Blinking timing chart 1. Subject Information of LED Flashing timing chart. 2. Contents When an abnormality has occurred the unit, the protection circuit operates and reset to the stand by mode. At this time, the defective block can be identified by the number of blinkes of the Power LED on the front panel of the unit.
TU-PT700U 10 Serviceman Mode (Electronic Controls) These Receiver and Plasma Display have electronic technology using the I C BUS Concept. It performs as a control function and it replaces many mechanical controls. Instead of adjusting mechanical controls individually, many of the control function are now performed by using “On Screen Display Menu”.
