IMPORTANT SERVICE SAFETY PRECAUTION

WA R NIN G

1. F or continue d s a fe ty, no modifica tion of any circ uit s hould be

a ttempte d.

2. Disconnect AC power before servicing.

BEFORE RETURNING THE RECEIVER (Fire &

Shock Hazard)

B efore returning the rec eiver to the user, perform the following

safety checks:

3. Ins pect all lead dres s to make certain that leads are not pinched,

and check that hardware is not lodged between the chassis and

other metal parts in the receiver.

4. Ins pect all protective devices s uch as non-metallic control knobs ,

ins ula tion ma te ria ls , c a binet ba cks , a djus tme nt and c ompa rtment

covers or s hields, is olation res ist or-capacitor net works , mechanical

ins ulators , etc.

5. To be sure that no shock hazard exists, check for leakage current in

the following manner.

• P lug t he AC cord directly int o a 110-240 volt AC outlet.

• Using two clip leads , c onnect a 1.5k ohm, 10 watt res isto r paral-

leled by a 0. 15 F capacit or in s eries wit h all exposed met al cabinet

parts and a known earth ground, s uch a s electrica l conduit or elec-

tric al ground connected to an ear th ground.

• Us e an AC voltmeter having with 5000 ohm per volt, or higher, sen-

sitivity or measure the AC voltage drop across the resistor.

• C onnect t he res is tor connection t o all expos ed metal parts having a

re turn to the cha s s is (a nte nna , me ta l ca bine t, s c re w he a ds , knobs

and control shafts , escutcheon, etc.) and measure the AC voltage

drop a cros s the re s is tor.

All checks mus t be repea ted with the AC cord plug connection

reversed. (If neces s ary, a nonpolarized adaptor plug mus t be us ed

only for the purpose of c ompleting these checks.)

Any rea ding of 0.74 Vrms (this corre s ponds to 0. 5 mA rms AC. ) or

more is exces s ive a nd indicates a potential s hock haza rd which

mus t be c orre cted before re turning the monitor to the owner.

SAFETY NOTICE

Many electrica l and mecha nical parts in L C D colour tele vis ion have

s pecial s a fety-related cha racteris tics .

T hes e cha racteris tics are often not evident from vis ual ins pection, nor

can protection afforded by them be neces s arily increas ed by us ing

replacement components rated for higher voltage, wattage, etc.

R eplacement parts which have thes e s pecial s afety characteris tics are

identified in this manual; elect rical components having such features

are identified by " " and shaded areas in the R eplacement P arts List

and S chematic Diagrams.

For continued protection, replacement parts must be ide ntical to those

us ed in the original circuit.

The us e of a substitute replacement parts which do not have the same

s a fe ty cha ra cteris tic s a s the fa c tory re c omme nde d re pla c e me nt pa rts

shown in this s ervice manual, may create s hock, fire or other hazards .
