resistance than specified, as follows :
B+ Line
Minimum Resistance
130 V
1 k (Hot chassis ground)
27 V
180 (Cold chassis ground)
17 V
110 (Cold chassis ground)
6. When the TV set is not used for a long period of time, unplug the
power cord from the AC outlet.
7. Potentials, as high as 32.0 kV are present when this TV set is in
operation. Operation of the TV set without the rear cover involves the
danger of a shock hazard from the TV set power supply. Servicing
should not be attempted by anyone who is not thoroughly familiar with
the precautions necessary when working on high voltage equipment.
Always discharge the anode of the picture tube to the CRT ground of
receiver before handling the tube.
8. After servicing make the following leakage current checks to prevent
the customer from being exposed to shock hazards.
1.2. LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connect a jumper between the two prongs on
the plug.
2. For physically operated power switches, turn power on. Otherwise
skip step 2.
3. Measure the resistance value, with an ohmmeter, between the
jumpered AC plug and each exposed metallic cabinet part on the
receiver, such as screwheads, connectors, etc. When the exposed
metallic part has a return path to the chassis, the reading should be
between 1 M and 12 M . When the exposed metal does not have a
return path to the chassis, the reading must be infinity.
1.3. LEAKAGE CURRENT HOT CHECK
1. Plug the AC cord directly into the AC outlet.
Do not use a isolation transformer for this check.
