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.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK ! 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.
4. Look for parts which, though 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.
