1-3 Safety Check-Out

1-4.Leakage Test

After correcting the original service problem, perform the following

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 . . Leakage current can be measured by any one of the three methods:1) A commercial leakage tester such as the SIMPSON 229 or RCA WT540A. Follow the manufacturers instructions to use those instructions. 2) A battery-operated AC milliampmeter The DATA PRECISION 245 digital . 3) Measuring the voltage drop across a resistor by means of a VOM or battery operated AC voltmeter. The 'limit' indication is 0.75V so analog meters must have an accurate low voltage scale. The SIMPSON'S 250 and SANWA SH63TRD are examples of passive VOMs that are suitable. Nearly all battery . (see Figure 2.)

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 inter board wiring to ensure that no wires are pinched or contact high-wattage resistors. ec a con ro no s, s e s, covers, groun s raps an moun ng hardware have been replaced. Be absolutely certain 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 recommen e r rep acemen . 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 rep acemen o any suc ne cor o e cus omer. 7) Check the antenna terminals, metal trim, metalized knobs, screws and all other exposed metal parts for AC leakage. Check leakage test as described next. 8. For safety reasons, repairing the Power board and/or Inverter board is pro e .

The reading should be zero ohms. 3) If a cold-water pipe is not accessible, connect a 60- to 100-watt troublelight (not a neon lamp) between the hot side of the receptacle and the . , , the lamp should light at normal brilliance if the screw is at ground potential (see Figure 3).
