For the customers in the Netherlands Voor de klanten in Nederland

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

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

Für Kunden in Deutschland

Entsorgungshinweis: Bitte werfen Sie nur entladene Batterien in die Sammelboxen beim Handel oder den Kommunen. Entladen sind Batterien in der Regel dann, wenn das Gerät abschaltet und signalisiert “Batterie leer” oder nach längerer Gebrauchsdauer der Batterien “nicht mehr einwandfrei funktioniert”. Um sicherzugehen, kleben Sie die Batteriepole z.B. mit einem Klebestreifen ab oder geben Sie die Batterien einzeln in einen Plastikbeutel.

the Z B/D, and connect the positive probe to the upper leg of B34 to check the Vzb voltage (_105 ± 1 V). When there is abnormality in the voltage turn the variable resistor (A2) of DC/DC Pack (_Vzb) on Z B/D to adjust it.

3) Measuring the Vs voltage margin and determining the voltage 1 Switch the signal of the signal generator to the

100% Full Red signal.

2 Turn the voltage adjusting knob of the Vs DC

power supply in the voltage-down direction, and turn off the cells of the screen.

3 Turn the voltage adjusting knob of the Vs DC

power supply in the voltage-up direction until the cells of the screen turn on. The first voltage, which turns on the cells of the entire screen, is named as Vsmin1. Record the value of Vsmin.

4 Turn the voltage adjusting knob of the Vs DC

power supply in the voltage-up direction slowly until the cells of the screen turn off or until overelectric discharge happens. The first voltage, which turns off the cells of the screen or causes over-electric discharge, is named as Vsmax1. Record the value of Vsmax1. (Note that the Vs voltage variable should exceed the maximum of 195 V.)

5 Switch the signal of the signal generator to the

100% Full Green signal.

6 Repeat the previous adjustment step (2), and

record each voltage as Vsmin2/Vsmax2.

7 Switch the signal of the signal generator to 100%

Full Blue signal.

8 Repeat the previous adjustment step (2), and

record each voltage as Vsmin3/Vsmax3.

9 Switch the signal of the signal generator to 100%

Full White signal.

0 Repeat the previous adjustment step (2), and

record each voltage as Vsmin4/Vsmax4.

!- Switch the signal of the signal generator to 100%

Full Black signal.

!= Repeat the previous adjustment step (2), and

record each voltage as Vsmin5/Vsmax5.

![ At this time, the maximum voltage is set by

adding 6 V to the Vs voltage (Vsmin1 to Vsmin5). Set the voltage within the setting range (180 V < Vs < 195 V) while considering other characteristics as well.

!] Turn the voltage adjusting knob of the Vs DC

power supply, and determine the Vs voltage.

!\ Adjust the Vset-down waveform by setting the Vs

voltage as described in 2-3-4.

4) Adjusting the final voltage waveform

1 Check the voltage waveform as described in 2-3-4

(3. How to adjust), and readjust the waveform when it is out of range.

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 picture appears 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.

. Change “1 GND” into ANODE, “2 Resistance” into

CATHODE, and then examine the diode in the forward or backward direction.

. Measure the resistance value (10 Ω).

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

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

2) Check if the connection connector of the X B/D that corresponds to the unusual screen is connected securely.

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

SAFETY CHECK-OUT

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

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

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA. Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers’ instructions to use these instruments.

2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)
