DETAILED DESCRIPTION OF ITEMS USED IN SERVICE
Enter FA mode
In "FA mode," playback of the pick-up area is adjusted first, and then playback verification process is done on all playable discs. Adjustments on initial playback need to be made when exchanging the Loader and MAIN BOARD ASSY in Service, so implement "FA mode" as in the following instructions.
1 Select "[1]Enter FA mode" with the up-and-down key on the remote control on the Service Mode screen and press the [ENTER] key. (Window below will appear)
2 The tray will open automatically, so insert GGV1368 and close the tray manually (push the tray in)
3 Adjustments will initiate, and when they are properly completed, the tray will re-open and
[Insert Disc: BD-R DL] will appear.
4 Remove the disc from the tray and press the [Stop] key. You will exit Service Mode
and return to the Home Menu screen and finish.
Jitter Measure / BLER Measure
Measures the Jitter or the Block Error Rate (BLER) of the disc inserted. Only Pass or NG will be displayed, not Measurement values. All of CD, DVD, and BD can be judged.
[ Instructions ]
1 Select "[7] Enter SP Mode" with the DOWN  key from the Service Mode screen, and press the [ENTER] key.
2 The SP Mode window menu will be displayed, so select either "Jitter Measure" "BLER Measure," and press the [ENTER] key.
3 The tray will automatically open and the dedicated screen will appear. Place the disc you wish to use on the tray, and push it in manually. ([Close] key will not function)
4 The tray will reopen automatically. Measurement will start when you push the tray in manually.
5 When test is completed, "Pass" or "NG" is displayed.
[ Effective indications ]
Defect related to playback (blocked noise, sound jumping, image jumping, disc is paused, freeze of screen etc.)
However, even if Pass is displayed after this test, it is difficult to determine that the Driver is normal with these Pass judgments only. If an NG is generated in a specific disc only, the defect is likely to be caused by the disc. If an NG is generated in other discs too, the defect is likely to be caused by the drive part.
Laser Check
Verifies the output value of each laser diode inside the pick-up area. Implement according to the following procedures.
1 Select "[4] Laser Check" with the b key from the Service Mode screen and press the "ENTER" key. (perform without disc in tray)
2 After a few seconds, measurement and judgment results will be displayed, and the tray will open automatically. If all Measurement values (Meas) are less than the total numeric value of the Target value (hex) and 80 (hex) combined, [PASS] will appear, and if any of them goes over, [NG] will appear.
BD
0x41d+0x80=0x49d , OK because Meas is 0x49d or less
DVD
0x53c+0x80=0x5bc, OK
Enter SP Mode
There are 15 items in the SP Mode, the main items being for Production line and Design/Development. The following is to explain items usable in Service. Other items require time for completion, or are not suited for Service purposes. If you select them by mistake, press the [Stop] key to end that item you accidentally selected. (none of the items will affect the main unit)
Simple Aging
Performs random playback of disc randomly. Implement the following process 800 cycles.
Tray close > . 50 times of short playback on voluntary points > Tray open
1cycle BD : 75 seconds x 800 times = Completed in a total of approx. 16 hours 40 minutes
DVD: Approx. 100 seconds x800 times = Completed in a total of approx. 22 hours 12 minutes
CD : Approx. 105 seconds x800 times = Completed in a total of approx. 23 hours 20 minutes
[ Instructions ]
1 Select "[7] Enter SP Mode" with the b key from the Service Mode screen, and press the [ENTER] key.
2 The SP Mode window menu will be displayed, so select "Simple Aging" and press the [ENTER] key.
3 The tray will automatically open and the dedicated screen will appear. Place the disc you wish to use on the tray, and push it in manually. ([Close] key will not function)
4 The tray will reopen automatically. Aging will start when you push the tray in manually.
Note 1: [Total test count] display should always be 1 (essentially, 9C40, which is the hex of the 40000, the total of Random 50-time playback x 800 times should be displayed.
Note 2: Accumulated sum for [Current test count] is counted up until "9C3D" (39997 in decimal), however later it is expressed as "32" and is finished.
