8. How to check a leakage current
1) Plug the power directly.
2) After connecting 1.5V 10W resistance and 0.15uF condenser in a row, link one with an
exposed metal part of TV set and earth the other (proper earth place such as water pipe).
9. A couple persons or more should perform the repair.
When a back cover needs to be separated, pull it out about half and remove the power cord
before complete uncovering.
10. Remove the anode cable which is fixed at HVG in separating the anode cable from HVG or
replacing CRT or HVG. Because a high voltage charged in the anode isn’t discharged
completely even though the AC power cord is removed, the high voltage can be sent to TV
set via the power cord and cause its damage.
Therefore, be sure to observe the following method in replacing a high voltage cable.
1) How to remove a high voltage cable
a. Make a discharger to discharge a high voltage.
b. Remove the power cord and wait for 30 sec.
c. Remove the anode cable after discharging as the method mentioned below.
2) How to produce
a. Solder MW resistance and clip lead.
b. Place the soldered part on a driver to tap.
3) How to discharge
a. Connect the clip with CRT NET GND.
b. Pull upward the anode cable slightly, giving a proper force to both nippers of the high
voltage plug locked in HVG. Then, the HVG is removed from the high voltage cable. Be
careful not to destroying the HVG plug socket which connects the high voltage plugs by
giving an excessive force to the nippers in the course.
c. To discharge a high voltage, contact the discharger with a peeled wire at the end of the
anode cable which is removed from HVG.
d. When separating the high voltage plug from the high voltage cable, put both tips of a
pincette in the plug and pull the plug to the end of the high voltage cable.
