The circuit boards used in these models have been processed using
Lead Free Solder. The boards are identified by the LF logo located
close to the board designation e.g. H1 etc [ see example ]. The
servicing of these boards requires special precautions to be taken as
outlined below.

It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints.
Lead Free Solder is available 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 requires soldering 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.com

The units in this manual contain a self-diagnostic function. If an error occurs, the POWER LED will automatically begin to flash. The
number of times the LED flashes translates to a probable source of the problem. A definition of the POWER LED flash indicators is
listed in the instruction manual for the user’s knowledge and reference. If an error symptom is difficult to reproduced use the
Remote Commander to display the record that is stored at the internal NVM to specify the cause of the failure.

Diagnostic Test  Indicators
When an error occurs, the POWER LED will flash a set number of times to indicate the possible cause of the problem. If there is
more than one error, the LED will identify the first of the problem areas. If the errors occur simultaneously, the one that corresponds
to the fewest flashes is identified first. Results for all of the following diagnostic items are displayed on screen. No error has occurred
if the screen displays a “0”.
