1. Check the area of your repair for unsoldered or poorly-solderedconnections. Check the entire board surface for solder splashesand bridges.

2. Check the interboard wiring to ensure that no wires are"pinched" or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularlytransistors, that were installed during a previous repair. Pointthem out to the customer and recommend their replacement.

4. Look for parts which, through functioning, show obvious signsof deterioration. Point them out to the customer andrecommend their replacement.

5. Check the B+ voltage to see it is at the values specified.6. FLEXIBLE Circuit Board Repairing

• Keep the temperature of the soldering iron around 270°Cduring repairing.

• Do not touch the soldering iron on the same conductor of thecircuit board (within 3 times).

• Be careful not to apply force on the conductor when solderingor unsoldering.

Unleaded solderBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed withthe lead free mark due to their particular size.)

: LEAD FREE MARKUnleaded solder has the following characteristics.• Unleaded solder melts at a temperature about 40°C higher than

ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350°C.Caution: The printed pattern (copper foil) may peel away if theheated tip is applied for too long, so be careful!

• Strong viscosityUnleaded solder is more viscous (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occur suchas on IC pins, etc.

• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer.

CAUTIONDanger of explosion if battery is incorrectly replaced.Replace only with the same or equivalent type.

DISCHARGING OF THE ST-163 BOARD’S CHARGING CAPACITOR (C901)

The charging capacitor (C901) of the ST-163 board is chargedup to the maximum 300 V potential.There is a danger of electric shock by this high voltage when thecapacitor is handled by hand. The electric shock is caused bythe charged voltage which is kept without discharging when themain power of the unit is simply turned off. Therefore, theremaining voltage must be discharged as described below.

Preparing the Short JigAs the discharging location is in depths, the short jig may touchto the opening of frame.Expose the tip of resistor of 1kΩ /1 W (1-215-869-11) by 1mmand insulate the rest of it with insulation tape.

• Constants of resistors, capacitors, ICs and etc with XXindicate that they are not used.In such cases, the unused circuits may be indicated.

• Parts with differ according to the model/destination.Refer to the mount table for each function.

• All variable and adjustable resistors have characteristiccurve B, unless otherwise noted.

• Signal nameXEDIT → EDIT PB/XREC → PB/REC

• 2: non flammable resistor• 5: fusible resistor• C: panel designation• A: B+ Line• B: B– Line• J : IN/OUT direction of (+,–) B LINE.• C: adjustment for repair.• A: not use circuit(Measuring conditions voltage and waveform)• Voltages and waveforms are measured between the

measurement points and ground when camera shootscolor bar chart of pattern box. They are reference valuesand reference waveforms.(VOM of DC 10 MΩ input impedance is used)

Precautions for Replacement of Imager• If the imager has been replaced, carry out all the adjustments

for the camera section.• As the imager may be damaged by static electricity from

its structure, handle it carefully like for the MOS IC.In addition, ensure that the receiver is not covered withdusts nor exposed to strong light.

The components identified by mark 0 or dotted line withmark 0 are critical for safety.Replace only with part number specified.

Les composants identifiés par une marque 0 sontcritiques pour la sécurité.Ne les remplacer que par une pièce portant le numérospécifie.
