SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH
MARK 0ON 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.
1. Check thearea ofyour repairfor unsolderedor poorly-soldered
connections. Checkthe entireboard surfacefor 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 CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.

2. EEPROM DATA INPUT
When EEPROM (IC182 on FR-169 board) is replaced with new one or “888” appears for short time on CH indicator afterAC plug OFF/ON,
perform the following procedure.
Fluorescent display tube
1) Connect the adjustment remote commander (RM-95: J-6082-053-B) with CN165 of MA-388 board by using LANC jig (J-6082-051-A).
2) Select page: 1, address: 00, and input data: 80.
3) Select page: F, and input data as following table.
8 88
Note: Press the PAUSE button of the adjustment remote commander each time to set the data.
4) Turn off the power to reset.
5) Perform “RF Switching Position Adjustment” and “AF Switching Position Adjustment”.
6) Make sure whether the function of the set works normally.
