1. Before Repairand Adjustment
DisconnectAC power, discharge PowerSupplyCapacitors C536, C545, C546 through a 10 ,
5Wresistorto ground.
DONOTSHORT-CIRCUITDIRECTLY(with a screwdriverblade, forinstance), as this may
destroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, to avoidovercurrent.
Current consumption atAC 230 V, 50 HzinNOSIGNALmode shouldbe ~400mA.
2. Protection Circuitry
The protection circuitrymayhave operatedifeitherof the following conditions are noticed:
-Nosound isheard whenthepoweristurnedon.
-Sound stopsduring aperformance.
The function of this circuitryis to prevent circuitrydamage if, forexample, the positive and
negative speakerconnection wires are
“shorted”, orifspeakersystems with animpedance less thanthe indicatedratedimpedance of
the amplifierare used.
Ifthis occurs, followthe procedure outlines below:
1. Turn off thepower.
2. Determinethecause oftheproblemand correct it.

3. Turn on thepoweronce againafteroneminute.
Note:
Whenthe protection circuitryfunctions, the unitwill not operate unless the poweris firstturned
off and thenon again.

4. Handling Precautions For Traverse Deck
The laserdiode inthe traverse deck (optical pickup) maybreak downdue to potential difference
causedbystatic electricityof clothes orhumanbody.
So, be careful of electrostatic breakdownduring repairof the traverse deck (optical pickup).
-Handling oftraverse deck (optical pickup)
1. Donotsubject thetraverse deck (optical pickup)tostatic
electricityas itisextremelysensitivetoelectrical shock.
2. Theshortland betweentheNo.4(LD) and No.5(GND) pinson the
flexibleboard (FFC) isshortedwithasolderbuild-up toprevent
damagetothelaserdiode.Toconnect tothePCboard, besureto
openbyremoving thesolderbuild-up, and finishtheworkquickly.

3. Take carenottoapplyexcessivestress totheflexibleboard
(FFC).
4. Donotturn thevariableresistor (laserpoweradjustment). Ithas
alreadybeenadjusted.
-Grounding for electrostaticbreakdownprevention
1. Humanbodygrounding
Use theanti-staticwrist straptodischargethestaticelectricity
from your body.
2. Worktablegrounding
Putaconductivematerial (sheet) or steel sheet on thearea
wherethetraverse deck (optical pickup)isplaced, and ground
thesheet.
Caution :
Thestaticelectricityofyour clothes will notbegroundedthrough
thewrist strap. So, take carenottolet your clothes touchthe
traverse deck (optical pickup).
Caution whenReplacing the Traverse Deck :

Thetraverse deck has ashortpointshortedwithsoldertoprotect
thelaserdiodeagainst electrostatics breakdown. Besureto
removethesolderfrom theshortpointbeforemaking
connections.

2. Donotadjust thevariableresistor on thepick up unit. Itwas
alreadyadjusted.
3. Donotlookat thefocuslensusing optical instruments.
4. Recommend nottolookat pick up lensfor along time.
