SERVICING NOTES
NOTES ON HANDLING THE OPTICAL
The laser diode in the optical
The flexible board is easily damaged and should be handled with care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
UNLEADED SOLDER
Boards 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 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.
RELEASING THE DISC TRAY LOCK
The disc tray lock function for the antitheft of an demonstration disc in the store is equipped.
Releasing Procedure:
1.Press the [?/1] button to turn on the system.
2.Press the [FUNCTION] button to select “BD/DVD”.
3.Press the [x] and [Z] buttons simultaneously and hold down unit “DEMO OFF” displayed on the fluorescent indicator tube (around 5 seconds).
Note: When “DEMO ON” is displayed, the disc tray lock is not released by turning power on/off with the [?/1] button.
ABOUT THE LENS CLEANING
Do not do the lens cleaning with the cotton bud etc. It causes the trouble.

Operation and Display:
1.BLX-104 Procedure:
1.Select 23.976Hz/1080p.
2.Play “4.Motion picture”.
3.Check whether player can play back or not.
4.Check each outputs. Video:
Composite/S Video/component/HDMI. Audio:
Speaker out.
*When 1080/24p monitor is nothing, 1080i (59.94Hz or 50Hz) can use instead of 1080/24p.
However this is temporary correspondence.
2.BLX-204 Procedure:
1.Select 1080i (59.94Hz or 50Hz).
2.Play “4.Motion picture”.
3.Check whether player can play back or not (Check the picture and sound output).
3.CD (HLX-A1) Procedure:
Check whether player can play back or not (Check the sound out- put).
4.HLX-513/514 (NTSC), HLX-506/507 (PAL)
Procedure:
1.After displayed Main Menu, select “1.Video Signal”.
2.Play “1.Color bar 100%” (Check the picture and sound out- put).
3.Return to Menu.
4.Play “Demonstration 4:3” or “Demonstration 16:9” (Check the picture and sound output).
