Check leakage asdescribed below.LEAKAGE The AC leakage from any exposed metal part to earth groundand from all exposed metal parts to any exposed metal part havinga return to chassis, must not exceed 0.5 mA (500 microampers).Leakage current can be measured by any one of three methods.1.A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers instructions to use theseinstruments.2.A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.3.Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examples ofa passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)Earth GroundACvoltmeter(0.75V)1.5k0.15FFig. A.

When this test is activated,all segments turn on at the same time, then each segment turns onone after another.* Procedure:While depressing the ENTER, the LEVEL and the EQ buttonssimultaneously, press the power 1/u button to turn on the mainpower. All segments turn on at the same time, then each segmentturns on press the ENTER button.FACTORY SET MODE* All preset contents are reset to the default setting.* Procedure:While depressing the SET UP, the LEVEL and the ENTER buttonssimultaneously, press the power 1/u button to turn on the mainpower. The message Factry Set appears and the present contentsare reset to the default values.ALL CLEAR MODE* All preset contents are cleared when this mode is activated. Usethis mode before returning the product to clients upon completionof repair.* Procedure:While depressing the SET UP button simultaneously, press thepower 1/u button to turn on the main power. The machine entersthe DEMO mode.DEMO mode: Wait a while, then thedemonstration starts. If the power 1/u button is pressed oftenthe demonstration has started, the power is turned off, and thedemonstration resumes if the power 1/u button is pressed again.ALL CLEAR mode; If the power 1/u button is pressed oftenthe machine enters the DEMO mode, but before the demonstrationstarts, the display is turned off. Press 1/u again. No response isreturned. The press 1/u again. The preset data is cleared andthe machine enters the normal power-on state.SOUND FIELD CLEAR MODE* The preset sound field is cleared when this mode is activated.Use this mode before returning the product to clients uponcompletion of repair.* Procedure:While depressing the SOUND FIELD MODE button, press thepower 1/u button to turn on the main power. The message S.FInitialize appears and initialization is performed.AM CHANNEL STEP 9 kHz/10 kHzSELECTION MODE (US,Canadian Model)* Either the 9 kHz step or 10 kHz step can be selected for the AMchannel step.* Procedure:Set the FUNCTION to AM. Turn off the main power.While depressing the TUNING+ button or the PRESET TUNING+ button, press the power 1/u button to turn on the main power.Either the message AM 9kHz Step or AM 10kHz Step appears.Select the desired step.DSP TEST MODE* It tests whether the DSP works correctly or not. When the DSPtest is activated, the test data is output from the DSP (IC1401:CXD2712R) of the DIGITAL board and is written in the RAM(IC1402: IDT71V016S). When the test data is read from the RAMby the DSP, the data output must be equivalent to the originaldata. If they disagree, an error is triggered. Errors can be causedby the broken data line or defective soldering.* ProcedureWhile pressing the SETUP, LEVEL and SUR buttons, press thePOWER button to enter the DSP test mode. The message DSPTEST MODE appears. When an error occurs, the message DSP2ERROR is displayed. When there is no error, the message DSP2NO ERROR appears and the 1 kHz signal is output to all channels.Then, the mode can be switched the (SIGN WAVE) (THROUGH)and (INPULSE) mode.VERSION MODE* When this mode is used, the microprocessor version number isdisplayed.* Procedure:Press the POWER button while pressing the ENTER, LEVEL,and SUR buttons to turn on the power. The microprocessor versionnumber appears as follows.SECTION 2SERVICING NOTE1. When the front panel is removed, the VR board is removed at thesame time. Consequently the LEDs cannot be turned on and thesound volume cannot be increased or decreased from the remotecontrol.2. When servicing the DIGITAL board, be sure to connect the earthland of the DIGITAL board with the chassis frame so that theearth potential of the DIGITAL board must not be floated fromthe chassis frame.Rear Panel1234567908!?!?!?!?!?!?!?!?!?1ANTENNA2DIGITAL35.1 CH INPUT4SPEAKERS (FRONT)5SPEAKERS (REAR)6SPEAKERS (CENTER)7WOOFER8INPEDANCE SELECTOR9AC power cord!AC OUTLET!S-LINK!2ND AUDIO OUT!VIDEO 1!VIDEO 2!DVD/LD(US, Canadian, Australian models)DVD(EXCEPT US, Canadian, Australian models)!TV/SAT(US, Canadian, Australian models)TV/LD(EXCEPT US, Canadian, Australian models)!TAPE (DE935 MODEL)!MD/DAT (DE935 MODEL)MD/TAPE (EXCEPT DE935)!CDPHONOMONITORSTR-DE835/DE935/SE591/V828 7 8 SECTION 4DIAGRAMSL58DATAFMAMFM75AMDOTUNEDT.
