  After correcting the original service problem, perform the following safety checks before releasing the set to the customer:

1.  Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface for solder 

splashes and bridges.

2.  Check the interboard wiring to ensure that no wires are “pinched” or touching high-wattage resistors.

3.  Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely 

certain that you have replaced all the insulators.

4.  Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out 

to the customer and recommend their replacement.

5.  Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and 

recommend their replacement.

6.  Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer.

7.   Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. 

Check leakage as described below.

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).

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).

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.

The AZ2-UK chassis is one of several designs for the 2011 model line 

of Sony Bravia® LCD televisions. This manual covers the following 

models:
 KDL32BX311
The chassis design revolves around the video processing circuits 

located on the A board. The key difference between models is 

determined by the size of the LCD panel and its manufacturing source. 

This manual will describe the new circuit features and individually 

describe the models based on these differences.

Several new features are introduced in this chassis model lineup 

along with some carryovers from the previous year.
