Y Display Tuner Version "ccc"

Y Display shows 32K Output at (Front Display Board) pin 19 of uP = 2048Hz N

Y Set is in Service PLAY Mode. In case of failures, error codes according to Table 2 will be displayed.

TUNER Button pressed?

O Button pressed? Service frequencies are copied to the RAM (see Table 1) Tuner works normally except: PROGRAM button

N

The Service Play Mode is intended to detect and identify the failures in the CD Mode. In this mode the electronics will still function even when an error is detected so that repair activities can be carried out.

Error code E1000

Error Description
Y

Focus Error Triggered when the focus could not be found within a certain time when starting up the CD or when the focus is lost for a certain time during play. Radial Error Triggered when the radial servo is off-track for a certain time during play. Sledge In Error The sledge did not reach its inner position (inner-switch is still close) before approximately 6 Sec. have passed by. Inner-switch or sledge motor problem. Sledge Out Error The sledge did not come out of its inner position (inner-switch is still open) before approximately 250 mSec. have passed by. Inner-switch or sledge motor problem. Jump-offtrack error Triggered in normal play when the jump destination could not be found within a certain time. When this error occurred, software will try to recover by initiating the jump command again. If it is recoverable, the disc will continue to play. Subcode Error Triggered when a new subcode was missing for a certain time during play. PLL Error The Phase Lock Loop could not lock within a certain time. Turntable Motor Error Generated when the CD could not reached 75% of speed during startup within a certain time. Discmotor problem. Focus Search Error The focus point has not been found within a certain time. The carousel switch is not open within certain time. This can happen when either the switch is defective and closed all the time, or when the carousel is blocked when located exactly at a disc position. The carousel position switch did not close within a certain time. This can happen when the switch is defective and never closes electrically, or when the carousel is blocked in between two disc positions. The time-out is approximately 5 Sec. The drawer could not enter the inside position is opening again. This can be caused because the drawer is blocked by something and cannot go fully inside, or the drawer switch is defective and does not close.

ACTION
A test pattern will be sent to the EEPROM. "PASS" is displayed if the uProcessor read back the test pattern correctly, otherwise "ERROR" will be displayed. Load default data. Display shows "NEW" for 1 second. Caution! All presets from the customer will be lost!! Display shows value for 2 seconds. Values increases or decreases in steps of 1 until 0 (Min.) or 40 (Max.) is reached.

9 to Exit EEPROM FORMAT TEST Q

Note: * Depending on the selected grid frequency (9 or 10kHz) By holding the TUNER and R buttons depressed while switching on the Mains supply, one of the undermentioned features will be activated: - the tuning grid frequency is toggled between 9kHz and 10kHz for the Oversea (/21) version. - the extended FM1 (65.81MHz - 74MHz) is toggled on and off for East Eur. (/34) version.
