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 270Cduring 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.

SECTION 1SERVICE NOTE

COVERCOVER

1-1. SERVICE NOTE1. POWER SUPPLY DURING REPAIRSIn this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the power is shut off sothat the unit cannot operate.This following two methods are available to prevent this. Take note of which to use during repairs.

Method 1:Use the AC power adaptor (AC-L10, AC-VQ800 etc.).

Method 1:Connect the servicing remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the commander switch to the ADJ side.

2. TO TAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)1 Refer to 2-3 to remove the front panel assembly.2 Refer to 2-5 to remove the top cabinet assembly.3 Refer to 2-6 to remove the cabinet (R) assembly.4 Refer to 2-7 to remove the battery panel section.5 Remove the EVF block.6 Open the VA-117 board.7 Disconnect CN1010 (27P, 0.3mm) of VC-281 board.8 Open the cassette lid.9 Supply +4.5V from the DC power supply to the loading motor and unload with a pressing the cassette compartment.

1-2. SELF-DIAGNOSIS FUNCTION1. SELF-DIAGNOSIS FUNCTIONWhen problems occur while the unit is operating, the self-diagnosisfunction starts working, and displays on the viewfinder, LCD screenor LCD window what to do. This function consists of two display;self-diagnosis display and service mode display.

Details of the self-diagnosis functions are provided in the Instructionmanual.

Note: The self-diagnosis display data will be kept even if the lithium battery (CK-108 board BT5201 of the cabinet (R) assembly) is removed.

2. SELF-DIAGNOSIS DISPLAYWhen problems occur while the unit is operating, the counter of theviewfinder, LCD screen or LCD window consists of an alphabetand 4-digit numbers, which blinks at 3.2 Hz. This 5-character displayindicates the repaired by: , block in which the problem occurred,

and detailed code of the problem.

3. SERVICE MODE DISPLAYThe service mode display shows up to six self-diagnosis codes shown in the past.

3-1. Display MethodWhile pressing the STOP key, set the switch from OFF to VCR , and continue pressing the STOP key for 5 seconds continuously. Theservice mode will be displayed, and the counter will show the backup No. and the 5-character self-diagnosis codes.

3-2. Switching of Backup No.By rotating the control dial, past self-diagnosis codes will be shown in order. The backup No. in the [] indicates the order in which theproblem occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)[1] : Occurred first time [4] : Occurred fourth time[2] : Occurred second time [5] : Occurred fifth time[3] : Occurred third time [6] : Occurred the last time

3-3. End of DisplayTurning OFF the power supply will end the service mode display.

(Measuring conditions voltage and waveform) Voltages and waveforms are measured between the measure-

ment points and ground when camera shoots color bar chart ofpattern box. They are reference values and reference wave-forms. *(VOM of DC 10 M input impedance is used.).

Voltage values change depending upon input impedance of VOMused.) *

1. Connection

2. Adjust the distance so that the output waveform of Fig. a andthe Fig. b can be obtain.

HIS NOTE IS COMMON FOR WIRING BOARDS AND SCHEMATIC DIAGRAMSn addition to this, the necessary note is printed in each block)

Transistor Diode

When indicating parts by reference number, please includethe board name.

or printed wiring boards): Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

hrough hole is omitted.Circled numbers refer to waveforms.

here are few cases that the part printed on diagram isn tmounted in this model.Chip parts.

or schematic diagrams)All capacitors are in F unless otherwise noted. p: pF.

0V or less are not indicated except for electrolytics andantalums.

Chip resistors are 1/10W unless otherwise noted.=1000 , M=1000k .

Caution when replacing chip parts.New parts must be attached after removal of chip.Be careful not to heat the minus side of tantalum capacitor, Be-

ause it is damaged by the heat.ome chip part will be indicated as follows.

Constants of resistors, capacitors, ICs and etc with XX indicatehat they are not used.n such cases, the unused circuits may be indicated.

All variable and adjustable resistors have characteristic curve B,nless otherwise noted.ignal name
