The boards are identified by the LF logo locatedclose to the board designation e.g. F1, H1 etc [ see examples ]. Theservicing of these boards requires special precautions to be taken asoutlined below.CAUTIONLead Free Soldered Boardsexample 1example 2It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder isavailable under the following part numbers :Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requiressoldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.For more information on the use of Lead Free Solder, please refer to http://www.sony-training.comr e b m u n t r a P r e t e m a i D s k r a m e R9 1 - 5 0 0 - 0 4 6 - 7 m m 3 . 0 g K 5 2 . 00 2 - 5 0 0 - 0 4 6 - 7 m m 4 . 0 g K 0 5 . 01 2 - 5 0 0 - 0 4 6 - 7 m m 5 . 0 g K 0 5 . 02 2 - 5 0 0 - 0 4 6 - 7 m m 6 . 0 g K 5 2 . 03 2 - 5 0 0 - 0 4 6 - 7 m m 8 . 0 g K 0 0 . 14 2 - 5 0 0 - 0 4 6 - 7 m m 0 . 1 g K 0 0 . 15 2 - 5 0 0 - 0 4 6 - 7 m m 2 . 1 g K 0 0 . 16 2 - 5 0 0 - 0 4 6 - 7 m m 6 . 1 g K 0 0 . 1- 4 -KDF-E42/50A11ERM-ED002e z i S e r u t c i P d e t c e j o r P) s e h c n i 2 4 ( m c 7 0 1 x o r p p AE 1 1 A 2 4 E - F D K) s e h c n i 0 5 ( m c 7 2 1 x o r p p AE 1 1 A 0 5 E - F D Kt u p t u O d n u o Sr e k a e p s t f e L d n a t h g i R ) S M R ( W 0 1 x 2 ) r e w o P c i s u M ( W 0 2 x 2] R A E R [ s l a n i m r e T t u p t u O / t u p n I s n o i t a c i f i c e p S l a r e n e Gr o t c e n n o c o r u E n i p - 1 2 : 1) d r a d n a t s C E L E N E C (. s l a n g i s o e d i V d n a o i d u A r o f s t u p n I.

In the event of an error occurring, the STANDBY LED indicator will automatically beginto flash. The number of times the STANDBY LED indicator flashes translates to a probable source of the problem. If an error symptom cannotbe reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how oftenthese problems occur.1. DIAGNOSTIC TEST INDICATORSWhen an error occurs, the STANDBY indicator will flash a set number of times to indicate the possible cause of the problem. If there is morethan one error, the indicator will identify the first of the problem areas.The result for all of the following diagnosis items are displayed on screen.
