Toshiba REGZA 42RV535U, Service Manual

Page: 7 / 232

Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15 µF, AC type capacitor,
between a known good earth ground (water pipe, conduit, etc.) and the exposed
metallic parts, one at a time. Measure the AC voltage across the combination of 1500
ohm resistor and 0.15 µF capacitor. Reverse the AC plug at the AC outlet and repeat
AC voltage measurements for each exposed metallic part. Voltage measured must not
exceed 0.3 volts rms. This corresponds to 0.2 milliamp. AC. Any value exceeding this
limit constitutes a potential shock hazard and must be corrected immediately.
Product Safety Notice
Many electrical and mechanical parts in this chassis have special safety-related
characteristics. These characteristics are often passed unnoticed by a visual inspection and
the protection afforded by them cannot necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement parts which have these
special safety characteristics are identified in this manual and its supplements; electrical
components having such features are identified by the international hazard symbols on the
schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The
use of substitute replacement parts which do not have the same safety characteristics as
specified in the parts list may create electrical shock, fire, or other hazards.
