Notes on Chip Component Replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged
by heat.
UNLEADED SOLDER
•
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.

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.
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
PA RT NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR

SERVICE NOTES
NOTE FOR REPLACEMENT OF THE EEP ROM (IC403)
The EEP ROM (IC403) contains all data by which the LCD screen is defined.
When the EEP ROM is replaced, the normal LCD screen will not appear.
It is then necessary to write the data into the EEP ROM.
Writing Method:
1. Turn on power to the connection box XA-125/126.
2. Press the [POWER] key on the set to turn on the set.
(Normal LCD screen doesn’t appear because there is no data in EEP ROM.)
3. Press the [RESET] key while pressing the [INPUT] and [VOL--] keys on the set.
4. Press the [VOL--] key on the remote controller for more than 2 seconds.
5. The EEP ROM data will be written and the normal test mode screen will appear.
After this, perform V COM voltage/position adjustment as well as VIDEO adjustment.
NOTE FOR REPLACEMENT OF THE SYSTEM CONTROL (IC401)
When the IC401 is replaced, the video system should be set again according to the destinations.
XVM-F65WL
