There is a highvoltage part inside.Avoidan

electricshockwhilethe electriccurrentis

flowing.

3. USE THE DESIGNATED PARTS The parts inthisequipment havethe specific

charactersof Incombustibilityand withstand voltageforsafety. Therafore, the partwhich is

replacedshouldbe used the part which has

the same chemcter.

Especiallyas to the importantparts forsafety which is indicatedin the cimultdiagramor the

tableof padsas a Z_ mark,the designated pads must be used.

There are pads which use the insulation

meteriblsuchas atube ortape for safety, or whichare assembledin the conditionthat

these de not contactwiththe pdntadboard. The insidewidngis designed notto get cinsor tothe pyrogenicpads and highvoltage parts.

Therefore, put thesepads in the originaf

positions.

5. TAKE CARE TO DEAL WITH THE CATHODE-RAY TUBE

Inthe conditionthat an explosion-proofcathode- raytube is set in this equipment, safetyis

securedagainstimplosion.However, when removingitor sendng frombackward,it is dangerousto give a shock.Take enoughcare to

deal withit.

6. AVOID AN X-RAY

Safetyle securedagainstan X-ray byconsider- ing about the cathode-ray tube and the high

voltagepedphorsicircuit,etc. Therefore, when rapalflngthe high voltagepe-

dpheral circuit, use the designated parts and makesure notrnodifythe cimuit.

raytube.

7. PERFORM A SAFETY CHECK AFTER SERVICING

Confirmthatthe screws,pads and wiring which were removedinorder to sendce am putin the odginalpositions,or whetherthereare the

portions which am deteriorated aroundthe serviced placesserviced ornot.Checkthe

2. Removethealdenna turmlnsl on TV andturn

an the'rV.

3. Insulationresistancebetweenthe cordplug

terminals end the etemaf exposure metal LTlote2] should be mere than 1M ohm by

using the 500V insulationreslstance meter

[Note1].

4. If the insulationresistance is lessthan 1M ohm,the inspectionrepairshouldbe

required.
