Very good as always. Also this manual appears clear and well processed. I know it will help me to work on this TV. Thank you a lot! Matteo
 ;
complete wiring diagram, without the part list. high quality copy. thanks for promptly.
 ;
Well done scan of a useful manual. It will be useful in my workbench!!
 ;
Excelent scan job. It's a fully detailed service manual of this model.
 ;
Do a quick order, scan quality is high.
I recommend to all!
1. Plug the AC cord directly into the AC outlet. Do not use a isolation transformer for this check. 2. Connect a 1.5 k , 10 W resistor, in parallel with a 0.15 F capacitor, between each exposed metallic part on the set and a good earth ground, as shown in Figure 1. 3. Use an AC voltmeter, with 1 k /V or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above measurements. 6. The potential at any point should not exceed 0.75 V RMS. A leakage current tester (Simpson Model 229 equivalent) may be used to make the hot checks. Leakage current must not exceed 1/2 mA. In case a measurement is outside of the limits specified, there is a possibility of shock hazard, and the receiver should be repaired and rechecked before it is returned to the customer.

2. X-RADIATION
WARNING :
1. The potential source of X-Radiation in TV sets is the High Voltage section and the picture tube. 2. When using a picture tube test fixture for service, ensure that the fixture is capable of handling 34.5 kV without causing X-Radiation.
NOTE:
It is important to use an accurate periodically calibrated high voltage meter.
