1 Safety Precautions

1.1. General Guide Lines

1. It is advisable to insert an isolation transformer in the AC supply before servicing a hot chassis.

2. When servicing, observe the original lead dress, especially the lead dress in the high voltage circuits.

If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.

3. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers, shields, and isolation R-C combinations, are properly installed.

4. When the receiver is not to be used for a long period of time, unplug the power cord from the AC outlet.

5. Potential, as high as 30.0kV, is present when this monitor is in operation. Operation of the Projection Monitor without the rear cover involves the danger of a shock hazard from the power supply. Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high voltage equipment. Always discharge the anode of the projection tube to the Projection Monitor chassis before handling the tube.

6. After servicing make the following leakage current checks to prevent the customer from being exposed to shock hazards.

1.2. Leakage Current Cold Check

1. Unplug the AC cord and connect a jumper between the two prongs on the plug.

2. Turn on the Projection Monitor´s power switch.

3. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the projection monitor, such as screw heads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis, the reading should be

between 4 MΩ and 20 MΩ.

When the exposed metal does not have a return path to the chassis, the reading must be

TX-51P950M / TX-51P950X / TX-43P950M / TX-43P950X

Fig. 1

1.4. X-Radiation

Warning :

1. The potential sources of X-Radiation in projection monitor are the High Voltage section and the projection tube.

2. When using a projection tube test jig for service, ensure that jig is capable of handling 31.5kV without causing XRadiation.

Note:

It is important use an accurate periodically calibrated high voltage meter.

1. Set the brightness to minimum.

2. Set the service switch to the service position.

3. Measure the High Voltage. The meter reading should indicate 31.5(+1.0,-1.5kV). If the meter indication is out of tolerance, immediate service and correction is required to prevent the possibility of premature component failure.

4. To prevent an X-Radiation possibility, it is essential to use the specified projection tube.

1.3. Leakage Current Hot Check (See Fig.1)

1. Plug the AC cord directly into the AC outlet. Do not use an

isolation transformer for this check.

2. Connect a 2kΩ, 10W resistor, in series with an exposed

metallic part on the projection monitor and an earth such as a water pipe.

3. Use an AC voltmeter, with high impedance type, to

measure the potential across the resistor.

4. Check each exposed metallic part, and measure the

voltage at each point.

5. Reverse the AC plug in the AC outlet and repeat each of the

above measurement s.

6. The potential at any point should not exceed 1.0V rms. In

case a measurement is outside of the limits specified, there is a possibility of a shock hazard, and the projection monitor should be repaired and rechecked before it is returned to the customer.
