Hoe u de batterijen moet verwijderen, leest u in de tekstvan deze handleiding.

Gooi de batterij niet weg maar lever deze in als kleinchemisch afval (KCA).

Für Kunden in Deutschland

Entsorgungshinweis: Bitte werfen Sie nur entladeneBatterien in die Sammelboxen beim Handel oder denKommunen. Entladen sind Batterien in der Regel dann,wenn das Gerät abschaltet und signalisiert “Batterieleer” oder nach längerer Gebrauchsdauer der Batterien“nicht mehr einwandfrei funktioniert”. Umsicherzugehen, kleben Sie die Batteriepole z.B. miteinem Klebestreifen ab oder geben Sie die Batterieneinzeln in einen Plastikbeutel.

2) Checking the DC/DC pack voltage1 Switch the signal of the signal generator to the

100% Full White signal.2 Connect the GND probe of DVM to the R16’s

right leg of the Y B/D, and connect the positiveprobe to the left leg of R30 to check the V1stvoltage (115 ±1 V). When there is abnormality inthe voltage, turn the variable resistor PS1 of DC/DC Pack (V1st) on Y B/D to adjust it.

3 Turn the voltage adjusting knob of the Vs DCpower supply in the voltage-up direction until thecells of the screen turn on. The first voltage, whichturns on the cells of the entire screen, is named asVsmin1. Record the value of Vsmin.

4 Turn the voltage adjusting knob of the Vs DCpower supply in the voltage-up direction slowlyuntil the cells of the screen turn off or until over-electric discharge happens. The first voltage,which turns off the cells of the screen or causesover-electric discharge, is named as Vsmax1.Record the value of Vsmax1. (Note that the Vsvoltage variable should exceed the maximum of195 V.)

5 Switch the signal of the signal generator to the100% Full Green signal.

6 Repeat the previous adjustment step (2), andrecord each voltage as Vsmin2/Vsmax2.

2-4-1. Checking for No Picture

Check the following points if the monitor shows the Full Black pattern or the power is off and no pictureappears on screen.

1) Check whether the CTRL B/D LED (D10, D11, D12, D13, D17) is turned on or not.2) Check the power and signal cable of the CTRL B/D.3) Check whether the X B/D, Y B/D, and Z B/D are plugged securely.4) Check the connection of the X B/D, Y B/D and Z B/D to the CTRL B/D.5) Measure the output wave of the X, Y, and Z B/D with the oscilloscope (200 MHz or more) and check

if there is any problem on the boards by comparing the output wave with the following figure.. Measurement point for the Y B/D : TP (Bead B50). Measurement point for the Z B/D : TP (Bead B35). Measurement point for the X B/D : COF TP

6) Check the SCAN (Y side) IC.7) Check the DATA (X side) COF IC.8) Replace the CTRL B/D.

How to examine Data COF IC

. Change “1 GND” into ANODE, “2 Resistance” intoCATHODE, and then examine the diode in the forwardor backward direction.

. Measure the resistance value (10 Ω).

3. An unusual pattern corresponding to the DataCOF IC unit is shown

1) If an unusual pattern corresponding to the Data COFIC unit is displayed as shown below, the input to theData COF IC has a problem.

2) In the case of <Case 1, 2, 3>. Check the connection of the Data COF connector.. Replace the corresponding X B/D.

3) In the case of <Case 4, 5>. Check the connector that connects the CTRL to the

X B/D.. Replace the corresponding XB/D or CTRL B/D.

4. Regular stripes that correspond to the area ofone or more DATA COF ICs are displayed

1) If the stripes that correspond to the area of one DataCOF IC are displayed regularly, the output from theoutput platform of the X B/D has a problem.If the stripes that correspond to the area of two DataCOF ICs are displayed regularly, the data from theCTRL B/D is not transmitted correctly.

2) Check if the connection connector of the X B/D thatcorresponds to the unusual screen is connectedsecurely.

3) Replace the corresponding XB/D or CTRL B/D.

2. Standardization of PartsSome repair parts supplied by Sony differ from thoseused for the unit. These are because of parts common-ality and improvement.Parts List has the present standardized repair parts.

3. Stock of PartsParts marked with “o” at SP (Supply Code) column ofthe Spare Parts list may not be stocked. Therefore, thedelivery date will be delayed.Items with no part number and no description are notstocked because they are seldom required for routineservice.

SAFETY CHECK-OUT

After correcting the original service problem,perform the following safety checks beforereleasing the set to the customer :

Check the metal trim, “metallized” knobs,screws, and all other exposed metal parts for ACleakage. Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part toearth ground and from all exposed metal parts toany exposed metal part having a return tochassis, must not exceed 0.5 mA. Leakagecurrent can be measured by any one of threemethods.

1. A commercial leakage tester, such as theSimpson 229 or RCA WT-540A. Follow themanufacturers’ instructions to use theseinstruments.

2. A battery-operated AC milliammeter. TheData Precision 245 digital multimeter issuitable for this job.

3. Measuring the voltage drop across a resistorby means of a VOM or battery-operated ACvoltmeter. The “limit” indication is 0.75 V, soanalog meters must have an accurate low-voltage scale. The Simpson 250 and SanwaSH-63Trd are examples of a passive VOMthat is suitable. Nearly all battery operateddigital multimeters that have a 2 V AC rangeare suitable. (See Fig. A)
