SECTION 1 - SAFETY AND FEATURES
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all exposed
metal parts to any exposed metal part having a return to chassis, must not exceed
0.5 mA(500 microamperes). Leakage current can be measured by any one of three
methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instructions.
2. A battery-operated AC milliampmeter. The Data Precision 245 digital
multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM
or battery-operated AC voltmeter. The “limit” indication is 0.75
V, so analog meters must have an accurate low voltage scale.
The Simpson’s 250 and Sanwa SH-63TRD are examples of
passive VOMs that are suitable. Nearly all battery-operated digital
multimeters that have a 2 VAC range are suitable (see Figure A).
HOW TO FIND A GOOD EARTH GROUND
The cover-plate retaining screw on most AC outlet boxes is at earth ground.Verify
the AC outlet box retaining screw ground by connecting a 60-to 100-watt trouble-
light (not a neon lamp) between the hot side of the receptacle and the retaining
screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should
light at normal brilliance if the screw is at ground potential (see Figure B).

SELF DIAGNOSIS FUNCTION
The TVs in this manual contain a self-diagnostic function. If an error occurs, the standby LED will automatically begin to flash. The number of
times the LED flashes translates to a probable source of the problem. A definition of the standby LED flash indicator is listed in the Operating
Instruction manual for the user’s reference.
If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal
If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal
past problems and how often these problems occur.

FEATURES
Several new features are introduced in this chassis model lineup
along with some carryovers from the previous year.
NAVIGATION MADE EASY
Enjoy an easy-to-use menu that allows you to navigate additional
content or adjust the picture settings while watching your favorite
program.
LIGHTSENSOR™ TECHNOLOGY
Enjoy customized picture brightness and save energy without lifting
a finger. The built-in Light Sensor automatically adjusts the picture
brightness based on the amount of light in the room.
X-REALITY™ ENGINE
Enjoy a vivid, lifelike picture experience. Sony’s X-Reality engine
brings out the best by analyzing each scene so you see sharpened
images, and amazing contrast detail.
PRESENCE SENSOR
Save energy when you’re not around. The television’s built-in motion
sensor has the ability to scan the room and detect movement. If the
sensor detects no movement it automatically turns off the picture
leaving only sound. After more time and no movement, the TV turns
itself off minimizing any unnecessary power draw.
