SAFETY PREC AUTIONS

V-2134EE V-2124EE V-2104EE
1. The design of this product contains special hardware, many circuits and components specially for safety purposes. For continued prot ection, no changes should be made to the original design unless authorized in writing by the manufact urer.
Replacement parts must be identical to thos e used in the original circuits. Service should be performed by qualified personnel only .
2. Alterations of the design or circuitry of the products should not be made. Any design alterations or additions will void the manufact urer's warranty and will further relieve the manufacturer of r es p onsi bil i ty for per sona l inj ur y or p r op er t y dam age r es ul t in g therefrom.
3. Many electrical and mechanical parts in the products have special safety-related cha ra cteristics. T hese ch aracteristics are often not e v i den t fr om v i sual i ns p ec ti on n or c a n the pr o tec tio n affor ded by them nec e s sar i l y b e ob tai ned by u s in g r ep l ac em en t com ponent s ra t ed for hig her vo l tag e, w at t ag e, etc . R ep l ac em en t parts which have these special safety charact eristics are
identified in the parts list of Service manual. Electrical
com ponents having such featur es are identified by sha di ng on t he sche matic s and by (!!!! ) on the parts list in Service manua l. The us e of a substitute replacemen t which do es n ot
have the same safety characteristics as the recommended r epl ac em ent par t s h ow n i n th e p ar t s li st of Ser v i ce m anual m ay
cause shock, fire, or other hazards.
4. Don't short between the LIVE side ground and ISOLATED
(NEUTRAL) side ground or EARTH side ground when repa iring.
Some model's power circuit is partly different in the GND. The difference of the G ND is shown by the LIVE : (") side GND, the ISO LAT E D(N EU TR AL) : ( #) si de G ND and EAR TH : ( $) side GND. Don't short between the LIVE side GND and
ISOLATED(NEUTRAL) side GND or EARTH side GND and n ev er m ea sur e wit h a m ea sur i ng appar atus (os ci l lo s cope et c. ) th e LIVE si de GN D an d ISOLA TED(NE UTRAL) side G ND or EAR TH side GND at the same time. If above no te will no t be kept, a fuse o r any parts will be bro k en.
5. If any repair has been made to the chassis, it is recommended that t he B1 set ting should be checked or adjusted (See ADJUSTMENT OF B1 POWER SUPPLY).
6. The hi gh v ol ta ge app lie d t o th e pi c tu r e t u be mu s t c on for m w it h th at sp ecified in S ervice manual. E xcessive h igh vo lt age ca n
cause an increase in X-Ray emission, arcing and possible component damage, t herefore operation under excessive high voltage conditions should be kept to a minimum, or should be prevented. If severe arcing occurs, remove the AC power
immediately and determine the cause by visual inspection (incorrect in stallat ion, cr acke d or m elte d high voltage harness, p oor s o ld er i ng, etc.) . To m ai nt ai n the proper mi n im u m l e v el of sof t X- Ray em ission, c ompon ents i n the high voltage ci rcuitry including the pict ure tube must be t he exact r epl acements or
alternatives approved by the manufacturer of the complete product.
7. Do not chec k high voltage by drawing an arc. Use a high voltage meter or a high v oltag e pr obe wit h a VTVM . Di scha rge the picture tube before attempting meter connection, by c onnecting
a cl i p le ad to t h e gr ou nd f ra me a nd c onn ec ti n g t h e oth er end of t he le ad through a 10kΩ 2W resi s to r to the an od e butt on .
8. W hen s e r vic e is r equ ir e d, obser v e th e or i gi na l l ea d dr es s. E x tr a pr ecaut i on sh ould be give n t o ass ur e c or r ect l ead dres s in th e high voltag e cir cuit area. W her e a short ci rcui t has occu rr ed, th os e comp onent s tha t indi c a te evi de nc e of ov e r heat i ng shoul d
be replaced. Always use the manufacturer's replacement components.
9. Is olation Check
(Safety for Electr ical Shock Hazard)
After re-ass embling the product, always perform an isolat ion check on the exposed metal parts of the cabinet (antenna
terminals, video/audio input and output terminals, Control knobs, m etal c abi n et, sc r ewhead s, ea r ph one j ac k, c on tr ol s haf ts , et c. ) to be sure th e pr oduct is s af e to operate without d anger of el ectri c al shoc k.
(1) Diele ctric Stre ngth Test
The is o l ati on bet ween the AC pr im a ry c i rcu i t and all me t al part s exposed to the user, particularly any exposed metal part having a r etu rn pat h to the chas s is s ho ul d wi thst an d a v ol t age of 3 000 V A C (r.m.s.) for a perio d o f on e second.
( . . . . W iths tand a v o lt age of 110 0V A C ( r .m. s .) to an ap pl i anc e
r ate d up t o 12 0V, an d 3 000V AC ( r .m. s .) t o an appl i an c e r ated 200V or m ore , for a period of one s econd. ) This method of test requires a test equipment not generally found in the service trade.
(2) L eakage Curr ent Check
Plug the AC line c ord directly into the AC outlet (do not use a line isolation transf ormer during this check.). Using a "Leakage
Current Tester", measure the leakage current from each exposed metal part of the ca bine t, particu larly any e xpos ed metal part having a return path to the chassis, to a known good earth gr ou nd (w a ter pi pe, e tc .) . A n y l eak a ge c ur r en t m ust n ot e x c eed
0 .5m A AC (r.m.s. ). However, in tropical area, this must not exceed 0.2mA AC (r.m.s.).
"
" Alternate Check Method
""
Plug the AC line c ord directly into the AC outlet (do not use a line isolation tran sformer dur ing t his che ck.). Use an AC voltmeter
