IMPORTANT SAFETY NOTICE
There are special components used in Panasonic Monitor sets which are importantfor safety. These parts are shaded on
the schematic diagram. It is essential that these critical parts should be replaced with manufacturer's specified parts to
prevent X·Radiation, shock, fire, or other hazards. Do not modify the original design without permission of PANASONIC
BROADCAST & TELEVISION SYSTEMS COMPANY.
WARNING: This equipment has been tested and found to comply with the limits for a class A digital device, pursuant to Part 15 of

SAFETY PRECAUTIONS
General Guidelines
1. It is advisable to insert an isolation transformer in the AC
power line beforeservicinga hotchassis.
2. 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
damagedby the short circuit.
3. After servicing, see to it that all the protective devicessuch
as insulation barriers, insulation papers, Shields, and
isolationR-Ccombinations,are properly installed:
4. Before switching the power on, measure the resistance
between B+ line and cold side chassis ground. Connect
the"-" side of an ohmmeterto the B+ line, and the"+" side
to chassis ground. Each line must have more resistance
value than the specified one asfollows:
B+ Line Minimum Resistance
210V (TPP1) 10 kQ
210V (TPP2) 10kn
41V (TPP3) 3kQ
15V (A6 pin 1) 5kn
12V(IC503pin 3) 500
the AC powercord plugfromthe AC line outlet.
6. High voltage points, as high as 31.5±0.3kV, are present
when the set is in operation.Operatingthe set without the
rear cover involves in a dangerous electrical shock from
the set power supply. Servicingmust not be attempted by
anyone who is not thoroughly familiar with the necessary
precautions when working on high voltage equipment.
Always discharge the anode of the picture tube to chassis
ground beforehandling the picturetube.
7. After servicing, make the following leakagecurrent checks
to preventthe customer from getting a dangerous electrical
shock.
Leakage Current Cold Check
1. Unplug the AC power cord and short between the two
prongs ofthe AC plug with ajumper wire.
2. Setthe powerswitch of this set to ONposition.
3. Measure the resistance value with an ohmmeter between
the shorted AC plug and each exposed metallic part of the
set cabinet such as screwheads, connectors, and control
shafts. When the exposed metallic part has a return path
to the chassis, the reading should be more than 1Mn.
When the exposed metal part does not have a return path
tothe chassis,the readingmustbe infinity.
-r OT-M3050W
Leakage Current Hot Check (SeeFig. 2-1)
1. Plugthe AC power cord directly into the AC line outlet. Do
not use an isolationtransformerfor this check.
2. Connect a 1.Skn 10 watt resistor in parallelwith a 0.15pf
capacitor between each exposed metallic part of the set
and an earth groundsuch as a water pipe.
3. Use a high impedance AC voltage meter to measure the
voltageacrossthe resistor.
4. Measurethe voltage at each exposedmetallicpart.
5. Reverse the AC plug inserting direction at the AC line
outlet and repeateach of the above measurements.
6.The voltageat any point mast be lessthan 0.75Vrms.
7. A leakage current tester (Simpson Model 229 or the
equivalent) may be used to make the hot checks. In this
case, thecurrent must be lessthan S00µA.
8. If the reading is more than the above value, the set must
be repaired and rechecked before it is returned to the
customerbecauseof a possibilityof anelectrical shock.

EXPLANATIONOF HIGH VOLTAGECIRCUITAND X-RADIATION
PROTECTIVE CIRCUIT
1. Automatic High Voltage Regulator
High voltage divided by FBT (T552) intern.al bleeder
resistor is oulput from pin 13 as the high potential
detecting voltage which is converted to a low impedance
voltage by 0513 and 0514. The voltage is input to pin 3
("+" input) of operational amplifier IC504 through
potentiometerR547.
The potential difference between this input voltage and a
reference vottage of pin 2 ("·' input) output from a resistor
dividing network (R580 and R582) is amplified and output
from pin 1to the base of 0515.
The change of 0515 collector current changes the base
current of Q516 and 0517. T504 and these transistors
configure a series chopper type regulator. The operation
ofthe regulatoris asfollows.

This loop can maintain1hestabilizedhigh voltage set by R547.
R547is set for 31.5±0.3kV.
As describedearlier, the basetrigger signal is applied from
FBTT552 to 0517. When 0517 swi1chesto on, a current
beginsto flow through P1·P2 of T504.
When 1hebase current of 0516 reaches to the specified
value,0517 switchesto off.
Controlling the time delay of the 0517 off operation
controls the output current of 0517 emitter. This also
controls the TPA11 voltage and the amplitude of 0552
collector purse which determines the high voitage o/ ihe

3. High Voltage Shut Down Circuit 4. Over Beam Current Protective Circuit
High voltage is regulated by the operation of section "1.
Automatic High Voltage Regulator". This circuit has a
feed-back loop. Even if one of the components in this loop
fails, the high voltage may be out of control.When the high
voltage exceeds approximately 34kV, the vol1ageoutput
from pin 11 of FBT (T552) increases. That voltage is
divided by R565, A593, A531, and R562, and inputto the
base of 0521. The emitter voltage of Q521 is inputto pin 3
{"+" input) of operational amplifier IC505 through R595,
R587,and R578.
When the beam current increases, the high voltage load
becomes heavier and the current of 210V line increases.
This current increase raises1hevoltage between both ends
of R871 and swi1chesQ853 to on. R871 is designed so
that 0853 can switch to on whenthe beam curren1exceeds
a certain level (less than 3.6mA). Switching 0853 to on
causes the current to let flow through R894, 0863, and
R847. It also causes Q844 to switth to on and 0842, Q841
and RL802to switchto off.
If the voltage exceeds the specified level,the voltageof pin
1 of IC505 goes high level. That high level cause Q844to
switch to on and 0841 and 0842 to switch to off. RL802
becomesoff and the set shutsdown.
5. EHT Decrease Circuit
- 6 -
When the beam current exceeds a certain level
(approximately4mA), D518, D527, and D530 switch to on
and lower the reference voltage (pin 2 of IC504) of the
above HighVoltageShut DownCircuit.
Because of this, when the beam current exceeds a certain
level,the voltage lowers andthe X-radiationdecreases.
