Sony MDS-JE630 service manual Retry Cause Display Mode, Procedure

RETRY CAUSE DISPLAY MODE

•In this test mode, the causes for retry of the unit during recording can be displayed on the fluorescent indicator tube. During playback, the “track mode” for obtaining track information will be set.

This is useful for locating the faulty part of the unit.

•The following will be displayed :

During recording and stop : Retry cause, number of retries, and number of retry errors.

During playback: Information such as type of disc played, part played, copyright.

These are displayed in hexadecimal.

Procedure:

1.Load a recordable disc whose contents can be erased into the unit.

2.Press the [MENU/NO] button. When “Edit Menu” is displayed on the fluorescent indicator tube, turn the [ÊÊÊÊÊÊÊÊAMSÊÊÊÊÊÊÊÊ]- ± knob to display “All Erase?”.

3.Press the [YES] button. (Or press the [ÊÊÊÊÊÊÊÊAMSÊÊÊÊÊÊÊÊ]- ± knob)

4.When “All Erase??” is displayed on the fluorescent indicator tube, the music calendar number blinks.

5.Press the [YES]button to display “Complete!!”, and press the [ÊÊ]p button immediately. Wait for about 15 seconds while pressing the button. (The [ÊÊÊÊÊÊÊÊAMSÊÊÊÊÊÊÊÊ]- ± knob can be pressed instead of the [YES]button for the same results)

6.When the “TOC” displayed on the fluorescent display tube goes off, release the [ÊÊ]p button.

7.Press the [RECÊÊÊ]r button to start recording. Then press the [ÊÊÊ]P button and start recording.

8.To check the “track mode”, press the [ÊÊÊÊÊ]á button to start play.

9.To release the test mode, press the [ÊÊÊÊÊ]1/u button, and turn OFF the power. When “TOC” disappears, disconnect the power plug from the outlet.

										Cause of Retry	Occurring conditions

	0	0	0	1	0	0	0	0	10	FCS incorrect	When not in focus
	0	0	1	0	0	0	0	0	20	IVR rec error	When ABCD signal level exceeds the specified range
	0	1	0	0	0	0	0	0	40	CLV unlock	When CLV is unlocked
	1	0	0	0	0	0	0	0	80	Access fault	When access operation is not performed normally

Reading the Display:

Convert the hexadecimal display into binary display. If more than two causes, they will be added.

Example

When 42 is displayed:

Higher bit: 4 = 0100 nb6

Lower bit : 2 = 0010 nb1

In this case, the retry cause is combined of “CLV unlock” and “ader5”.

When A2 is displayed:

Higher bit: A = 1010 nb7+b5

Lower bit : 2 = 0010 nb1

The retry cause in this case is combined of “access fault”, “IVR rec error”, and “ader5”.
