1. Safety Instructions
1.1 X-ray Radiation Precaution
Excessive high voltage can produce potentially hazardous X-ray radiation.
To avoid such hazards, the high voltage must not be above 31.0KV(14")
or 35.0KV(21") under any conditions. The normal value of the high
voltage of this television is 22.5KV(14") or 26.5KV(21") at max beam
current (maximum brightness) under a 90-260V, 50/60HZ AC power
source.
1.2 Safety Precaution
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary
precautions on this television. The followings are the necessary
precautions to be observed before servicing.
1). Since the chassis of this television is directly connected to the
AC-power line (HOT chassis), an isolation transformer should be used
２
during any dynamic service to avoid possible shock hazard.
2). Always discharged the picture tube anode to the CRT conductive
coating before handing the picture tube. The tube is highly evacuated and,
if broken, glass fragments will be violently expelled. Use shatterproof
goggles and keep picture tube away from the body while handing.
3). When replacing a chassis in the cabinet, it always is certain that all the
protective devices are put back in place, such as non-metallic control
knobs, insulating covers, shields isolation resistor-capacitor network, etc.
4). Before returning the set to the customer, always perform an AC
leakage current check on the exposed metallic parts of the cabinet such as
terminals, screws, metal overlays control shafts, etc., to insure that the set
is safe to operate without danger of electrical shock.
1.3 Product Safety Notice
Many electrical parts in this chassis have special safety-related
characteristics. These characteristics are often passed unnoticed by a
visual inspection and the protection afforded by them cannot necessarily
be obtained by using replacement, rated for higher voltage, wattage, etc.
Replacement parts with special safety characteristics must be identified in
this manual and its parts list. Before replacing any of these components,
read the parts list in this manual carefully. The use of substitute
replacement parts that do not have the same safety characteristics as
specified in the parts list may create shock, fire, X-ray radiation of other
hazards.
1.4 Automatic Degaussing
A degaussing coil is mounted around the picture tube, so that external
degaussing after mobbing the TV should be unnecessary. But the receiver
must be properly degaussed upon installation. The degaussing coil
operates for about 1 second after the power is switched ON. If the set is
moved or turned in a different direction, the power should be OFF for at
least 15 minutes. If the chassis or parts of the cabinet become magnetized,
poor color purity will result. If this happens, use an external degaussing
coil. Slowly move the degaussing coil around the faceplate of the picture
３
tube, the sides and the front of it, slowly withdraw the coil to a distance
of about 6 feet before turning power OFF.

2. Signal Block Diagram
This chassis is consisted of main chip LA76812 controlled by Sanyo
I C bus and CPU LC863232A.
LA76812 is a performance and quality IC including PIF, SIF, AFC,
V/C/D, etc circuits.
TDA7056B used in BTSC sound system is a power amplifier.
CXA2104S is a BTSC decode function IC.
LA4225A used in MONO sound system is another power amplifier
LA78040 is used for vertical power amplifier.

refer to a wider area, so that can be divided them two conditions to
explain: no +B 110 V and existing +B 110V.
