servicing of Combination DVD VCR whose chassis is not isolated
from the AC power line. Use a transformer of adequate power
rating as this protects the technician from accidents resultingin
personal injury from electrical shocks. It will also protect
Combination DVD VCR from being damaged by accidental
shorting that may occur during servicing.
3. When servicing, observe the original lead dress, especially the
lead dress in the high voltage circuits. If a short circuit is found,
replace all parts which have been overheated or damaged by the
short circuit.
4. After servicing, see to it that all the protective devices such as
insulation barriers, insulation papers, shield, and isolation R-C
combinations are properly installed.
5. Before turning the receiver on, measure the resistance between B+
line and chassis ground. Connect (-) side of an ohmmeter to the B
+ lines, and (+) side to chassis ground. Each line should have
more resistance than specified,as follows :
B+ Line
Minimum Resistance
130 V
1 k (Cold chassis ground)
27 V
180 (Cold chassis ground)
210 V
1 k (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 30.0 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 isnot
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
