------SAFETY PRECAUTIONS------
1-1 CAUTION:
No modification of any circuit should be attempted.
Service work should only be performed after you are
thoroughly familiar with all of the following safety
checks and servicing guide lines.
1-2 SAFETY CHECK
Care should be taken while servicing this CRT display
because of the high voltage used in the deflection cir-
cuits.
These voltages are exposed in such areas as the
associated flyback and yoke circuits.
1-3 FIRE & SHOCK HAZARD
1-3-1 Insert an isolation transformer between the CRT
display and AC power line before servicing chassis.
1-3-2 In servicing pay attention to original lead dress
especially in the high voltage circuit. If a short cir-
cuit is found, replace all parts which have been
overheated as a result of the short circuit.
1-3-3 All the protective devices must be reinstalled per
original design.
1-3-4 Soldering must be inspected possible for cold solder
joints, frayed
leads, damaged insulation, solder
splashes or sharp solder points. Be certain to remove
all foreign material.
1-4 IMPLOSION PROTECTION
All Panasonic picture tubes are equipped with an integral
implosion protection system, but care should be taken
to avoid damage and scratching during installation. Use
only Panasonic replacement picture tubes.
1-5 X-RADIATION
WARNING:
The only potential source of X-Radiation 1s
the picture tube. However when the high voltage circuitry
is operating properly there is no possibility of X-Radiation
problem. The basic precaution which must be exercised
is to keep the high voltage at the
following factory-
recommended level.
Note.
It is important to use an accurate periodically
calibrated high voltage meter.
1-5-1 To measu·re the high voltage, use a high impedance
h 1gh voltage meter.
Connect (-) to chassis and
(+) to
the CRT anode
button.
1-5-2 Turn the Brightness control fully counterclockwise.
1-5-3 Measure the h 1gh voltage. The h 1gh voltage meter
should indicate at the following factory-recorn-
mended level.
1-5-4 If the urr>er meter indication exceeds the maximum
level. immediate service is required to prevent the
possiblity
of
premature
component
failure.
1-5-5 To prevent X-Radiation possibility, it 1sessent1al to
use the specified picture tube.
1-5-6 The nominal high voltage is 7KV and must not
exceed BKV at zero beam current at rated voltage.
.....---- IMPORTANT SAFETY NOTICE------.
There are special components used in Panasonic CRT
displays which are important for safety. These parts are
identified on the schematic diagram and on the replace-
ment parts I ist. It is essential that these critical parts
should be replaced with manufacture's specified parts to
prevent X-RADIATION, shock, fire or other hazards. Do
not modify the original design without written permis-
sion of the Panasonic company and this will void the
original parts and labor guarantee.
-----GENERAL INFORMATIONS-----
The Model TR-60S1A is CRT DATA DISPLAY of metal
frame type.
TR-60S1A uses P31 (Green color) phosphor and polish
Cathode Ray Tube.
Input signal is separate type and each input signal is put
through 5 pin-header connector on the P.C. Board.
Input signal is for TTL level.
When connecting to equipment, directly connect it to print-
ed circuit board input terminal through 5 pin-header con-
nector.
In addition, +B is supplied from the outside through 5 pin-
header connector, operating the monitor on +12V DC.
Features:
CRT is exceptionally superb in quality and reliability and is
of polish type. Phosphor P31.
The deflecting coil is a yoke equipped with 4-P magnet and
is of PANASONIC's own design that permits adjustment of
geometric distortion on the raster.
Chassis is fully equipped with I Cs:
-1-
Vertical deflection
H. P.C. (horizontal phase control)
