SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer.
1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges.
2. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair . Point them out to the customer and recommend their replacement.
4. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend 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˚C during repairing.
Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).
Be careful not to apply force on the conductor when soldering or unsoldering.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY .
Unleaded solder
Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded 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 be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350°C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!
Strong viscosity Unleaded solder is more viscous (sticky , less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ! LES COMPOSANTS IDENTIFÉS P AR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMA TIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPÉMENTS PUBLIÉS PAR SONY.
CAUTION :
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.

• NOTE FOR REPAIR

1. SERVICE NOTE

Make sure that the flat cable and flexible board are not cracked of bent at the terminal. Do not insert the cable insufficiently nor crookedly.
Cut and remove the part of gilt which comes off at the point. (Take care that there are some pieces of gilt left inside)
When remove a connector, don't pull at wire of connector. Be in danger of the snapping of a wire.
When installing a connector, don't press down at wire of connector. Be in danger of the snapping of a wire.
[Discharging of the FLASH unit’s charging capacitor]
The charging capacitor of the FLASH unit is charged up to the maximum 300 V potential. There is a danger of electric shock by this high voltage when the capacitor is handled by hand. The electric shock is caused by the charged voltage which is kept without discharging when the main power of the DSC-T7 is simply turned off. Therefore, the remaining voltage must be discharged as described below.
Preparing the Short Jig
To preparing the short jig. a small clip is attached to each end of a resistor of 1 k /1 W (1-215-869-11) Wrap insulating tape fully around the leads of the resistor to prevent electrical shock.
Discharging the Capacitor
1 Remove the cabinet (front) assembly. 2 Peel off the absorbing sheet. 3 Remove the flexible board. 4 Short circuits between the positive and the negati ve terminals of
charged capacitor with the short jig about 10 seconds.
