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.

4.  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).

A cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on 

most AC outlet boxes is also at earth ground.
If the retaining screw is to be used as your earth ground, verify that it is at ground 

by measuring the resistance between it and a cold-water pipe with an ohmmeter. 

The reading should be zero ohms.
If a cold-water pipe is not accessible, connect 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).

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 

past problems and how often these problems occur.

Several  new  features  are  introduced  in  this  chassis  model  lineup 

along with some carryovers from the previous year.

Enjoy incredible depth and a sharp, Full HD 1080p picture from the 

leader in 3D technology. (3D Active Glasses required, sold separately) 

Experience  enhanced  picture  quality  and  contrast  with  local 

dimming technology. It sharpens image contrast giving an amazingly 

crisp picture you can see. The backlight system allows for a more 

environmentally friendly television than traditional CCFL-tube TVs. 

Sony’s  monolithic  design  consists  of  an  elegant  sheet  of  glass 

stretching from edge-to-edge. It looks just as good when it’s off as it 

does when it’s on. 

Sony’s exclusive panel technology boosts contrast and brightness, 

making for an enhanced viewing experience. 

See  smooth  and  precise  detail  during  fast-action  scenes.  Sony’s 

Motionflow XR 240 technology for fast action movies and sports by 

reducing blur caused by quick camera movements, enhancing image 

sharpness, and overall creates a clearer picture.
