Design and specifications are subject to change without notice.

(When letters/numbers appear in the display)When the self-diagnosis function is activated to prevent the system from malfunctioning, a 5-character service number (e.g. C 13 50) with a combination of a letter and 4 digits appears on the TV screen and the front panel display. In this case, check the following table.

Self-diagnosis Function

First 3 characters of the service number

Cause and corrective action

C 13 This disc is dirty. Clean the disc with a soft cloth .

C 31 The disc is not inserted correctly. Restart the system, then re-insert

the disc correctly.E XX(XX is a number)

To prevent a malfunction, the system has performed the self-diagnosis function. Contact your nearest Sony dealer or

local authorized Sony service facility and give the 5-character service number.Example: E 61 10

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 with

the 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 higherthan 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 ifthe heated tip is applied for too long, so be careful!

Strong viscosityUnleaded solder is more viscou-s (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.

Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.
