WARNING

The chassis inthis receiver ispartially hot.Use anisolation transformer between the linecord plugand power

receptacle, when servicing this chassis.

Toprevent electric shock, do notremove cover. Nouser-serviceable parts inside.Refer servicing to qualified

servicepersonnel.

IMPORTANT SERVICE NOTES

Maintenance and repair of this receiver should becarried out by qualified service personnel only.

SERVICING OF HIGHVOLTAGE SYSTEM AND PICTURE TUBE

When servicing the high voltage system, remove static charge from itby connecting a 10k ohm resistor in

series with an insulated wire(such astest probe) between picture tube ground tag and highvoltage lead.(AC

linecord shouldbedisconnected from AC outlet).

1.Picture tube inthis receiver employs integral implosion protection.

2.Replace with tube of the same type number for continuedsafety.

3.Donot lift picture tube bythe neck.

4.Handlethe picture tube only when wearing shatterproof goggles and after discharging the highvoltage

completely.

X-RAY

This receiver isdesigned so that any X-Ray radiationiskept to an absolute minimun.Since certain malfunctions

ar servicing may produce potentially hazardous radiation with prolonged exposure atclose range, the following

precautions should beobserved.

1.When repairing the circuit, besure notto increase the highvoltage to more than 30.0kV (atbeam 1000 U.A)

for the set.

2.Tokeep the set ina normaloperation, besure to make itfunction on 23.5kV + 1.5kV(at beamlOOO ,nA)in

the case of the set. The set has been factoryadjusted to the above mentioned highvoltage. Ifthere isa

possibility that highvoltage fluctuates as result of the repairs,never forget to check forsuch highvoltage

after the work.

3.Donotsubstitute a picture tube with unauthorized types orbrandswhich may cause excess X-Ray radiation.

BEFORE RETURNING THE RECEIVER

Inaddition to the checks necessary as a result of a repair havingbeen carried out, thefollowing additional

safety checks should also bemadebefore returning the unitsto the user.

1.Inspectalllead insulation to make certain that leads are notpinchedor that harwareisnotlodged

between the chassis and other metal parts inthe receiver.

2.Inspect allprotective devices such as non-metallic control knobs,, insulatingfishpapers, cabinet backs,

adjustament and compartament covers or shields,insolation resistor-capacity networks, mechanical

insulators,etc.

SERVICE ADJUSTMENTS ——

All the adjustments required for this chasis will bedone inService Mode, except G2 and Focus.

•G2ADJUSTMENT

1.Receive cross hatch pattern signal.

2. Set contrast to 80/100andbrightness to 40/100.

3.Connect the oscilloscope to the red cathode and adjust G2

to read145Von the sensor pulseas inbelow drawing:

NOTE:

Osciloscope should beadjustated for vertical

TV field trigger and synchronized with video signal.

•SERVICE MODE FUNCTION

Thismode function isprovided to assist with the settings of those adjustment thatmayvary from one

Picture Tube to another, or between models.
