PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in television receivers have special safety related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by
using replacement components rated for higher voltage, wattage, etc.
Replacement parts which have special safety characteristics are identified in this service manual.
Electrical components having such features are identified by shading on the schematic diagram and parts list of this
service manual. The replacement for any safety part should be identical in value and characteristics.
Pb Solder
The PWBs used in this chassis are constructed using Lead-Free Solder. When servicing use
only recommended Lead-Free Solder. Refer to the section “Using Lead Free Solder.”

SAFETY PRECAUTIONS
NOTICE:
WARNING:
1.
2.
Observe all cautions and safety related notes located inside the receiver cabinet and on the
receiver chassis.
Operation of this receiver outside the cabinet or with the cover removed presents a shock hazard
from the receiver's power supplies. Work on the receiver should not be attempted by anyone who is
not thoroughly familiar with the precautions necessary when working on high voltage equipment.
When service is required, observe the original lead dress. Where a short-circuit has occurred, replace
those components that indicate evidence of overheating.
SAFETY PRECAUTION
To protect your eyes, do not look directly into the lamp, or light coming directly from the lamp, lens or
mirror.
Leakage current check
Before returning the receiver to the customer, it is recommended that leakage current be measured according to the
following methods.
1. Cold Check
With the alternating current (AC) plug removed from the AC source, place a jumper across the two AC plug
prongs. Connect one lead of an ohm meter to the AC plug and touch the other lead to each exposed metal part
(i.e. antennas, handle bracket, metal cabinet, screw heads, metal overlay, control shafts, etc.), particularly any
exposed metal part that has a return path to the chassis. The resistance of the exposed metal parts having a
return path to the chassis should be a minimum of 1Meg Ohm. Any resistance below this value indicates an
abnormal condition and requires corrective action.
2. Hot Check ...Use the circuit shown below to perform the hot check test.
1. Keep switch S1 open and connect the receiver to the measuring circuit. Immediately after
connection, and with the switching devices of the receiver in their operating positions, measure the
leakage current for both positions of switch S2.
2. Close switch S1, energizing the receiver. Immediately after closing switch S1, and with the
switching devices of the receiver in their operating positions, measure the leakage current for both
positions of switch S2. Repeat the current measurements of items 1 and 2 after the receiver has
reached thermal stabilization. The leakage current must not exceed 0.5 milliampere (mA).

CAUTION:
Wear gloves when handling the Lenticular Screen and Fresnel Lens.
This prevents cuts and finger prints. Do not place Fresnel Lens in the sun.
This may cause fire and heat related injuries.
Lenticular Screen and Fresnel Lens Removal
1) After removing the top, bottom and side HOLDER-SCREEN rails and their cushions from the Bezel, lift the
screens as a single unit from the frame.
2) Separate the Lenticular Screen and Fresnel Lens.
Note: When separating the Lenticular Screen from the Fresnel Lens, use caution
while prying the Screen and Lens apart. Use a slot type screw driver, and
remove the pressure sensitive double sided tape.
Lenticular Screen and Fresnel Lens Replacement
1) Apply LENS-TAPE along the rear top edge of the Lenticular Screen.
2) Place the Fresnel Lens on top of the Lenticular Screen, and apply pressure along the top edge.
3) Place the screens in the screen frame and reinstall the cushions, top, bottom and side rails.
NOTE: The Lenticular Screen label must face the front and the Fresnel Lens label face the rear.
4) Reverse the Screen Removal Procedure and insert the screens in the Bezel.
