injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons,we advise all YAMAHA product owners that any service required should be performed by an authorizedYAMAHA Retailer or the appointed service representative.

IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification orrecognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.

The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, andservice departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitableand specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, pleasecontact the distributor's Service Division.WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have

accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss).IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (andpossibly other entities) to cause cancer and/or birth defects or other reproductive harm.DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-SON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or exposeeyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands beforehandling food.

TO SERVICE PERSONNEL1. Critical Components Information

Components having special characteristics are marked sand must be replaced with parts having specifications equalto those originally installed.

2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits.

Meter impedance should be equivalent to 1500 ohmsshunted by 0.15F.

CAUTIONF2: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A,125V FUSE.CAUTIONF2: REPLACE WITH SAME TYPE 10A, 125V FUSE.ATTENTIONF2: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 10A, 125V.

Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities.

About lead free solder / The P.C.B.s installed in this unit are soldered using thefollowing solder.

Side A

Side B

SMT REFLOW Process

MI FLOW Process

Solder Dip

Sn+Ag+Cu++Sn+Cu+Sn+Zn+Bi++

3040

Among some types of lead free solder currently available,it is recommended to use one of the following types for therepair work.

Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth)

Caution:1. As the melting point temperature of the lead free solder

is about 30C to 40C (50F to 70F) higher than that ofthe lead solder, be sure to use a soldering iron suitableto each solder.

2. If lead solder must be used, be sure to remove lead freesolder from each terminal section of the parts to bereplaced and from the area around it completely beforesoldering, or make sure that the lead-free solder andlead solder melt together fully.

When there is a history of protection function: :

Display provided when DIAG started

Cause: An excessive current flowed through the poweramplifier.

Turning on the power without correcting the abnormalitywill cause the protection function to work immediately andthe power supply will instantly be shut off.

Note) Applying the power to a unit without correcting the

abnormality can be dangerous and cause additionalcircuit damage.

The output transistors in each amplifier channelshould be checked for damage before applying anypower.

Amplifier current should be monitored by measuringacross the emitter resistors for each channel.

:

The FL display of the main unit displays the protectionfunction history data and the version (1 alphabet) and theDIAG menu (sub-menu MARGIN of DIAG menu No.1DA60Y-YSS930) a few seconds later.

When there is no history of protection function:

Starting DIAG in the protection cancelmode

If the protection function works and causes hindrance totrouble diagnosis, cancel the protection function as de-scribed below, and it will be possible to enter the DIAGmode. (The protection functions other than the excess cur-rent detect function will be disabled.)Press the MASTER ON/OFF key while simultaneouslypressing those two keys indicated in the figure above. Atthis time, keep pressing those two keys for 3 seconds orlonger.

In this mode, the SLEEP segment of the FL display of themain unit flashes to indicate that the mode is DIAG modewith the protection functions disabled.

Segment conditions of the FL driver and the FL tube arechecked by turning ON and OFF all segments. Next,the operation of the FL driver is checked by using thedimmer control. Then a short between segments nextto each other is checked by turning ON and OFF allsegments alternately (in lattice). (In the above example,the segments in the second row from the top areshorted.)

8. STRAIGHT / DISPLAY CHECKUse this program to check the FL display section andimage control section. When checking the image con-trol section, prepare a monitor, component video cable,S video cable and video pin cable and connect them.Using the sub-menu operation, the display status of theFL display section and image control section varies asshown below.For audio signal processing, use EFFECT OFF (L/Routput by using ANALOG MAIN BYPASS).

12. AD DATA CHECKThis menu is used to display the A/D conversion valueof the main Microprocessor which detects panel keys ofthe main unit and protection functions in using the sub-menu. During signal processing, the condition beforeexecution is maintained.When K0/K1 menu is selected, keys become non-operable due to detection of the values of all keys.However, it is possible to advance to the next sub-menu by turning the VOLUME of the main unit. Whenusing this function, note that turning the VOLUME morethan 1 click would cause the volume value to change.
