Repair Hints & Service Positions
1) During repair it is possible to disconnect the ECO6 Tuner
board and/or 5DTC Module completely unless the fault is
suspected to be in that area. This will not affect the
performance of the rest of the set.
Note: The flex cables are very fragile, care should be taken
not to damage them during repair. After repair, be
very sure that the flex cables are inserted properly
into the flex sockets before encasing, otherwise faults
may occurs.

Error Description
Focus Error
Triggered when the focus cannot be found within a certain time when starting up the CD, or if the focus
is lost for more than a certain time during playing of CD.
Radial Error
Triggered when the radial servo is off-track for a certain time during playing of CD.
Sledge In Error
The sledge did not reach its inner position (inner-switch is still close) before approximately 6 seconds
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 250ms
have passed by. Inner-switch or sledge motor problem.
Jump Error
Triggered in normal play when the jump destination could not be found within a certain time.
Subcode Error
Triggered when a new subcode was missing for a certain time during playing of CD.
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 start-up within a certain time. Disc
motor problem.
Focus Search Error
The focus point has not been found within a certain time.
The tray could not enter the inside position and is opening again. This can happen if the tray is blocked
such that it cannot go fully inside, or if the 5DTC control module is defective and never closes.
The tray could not reach the outside position and is stopped at its blocked position. This can happen if
the tray is blocked such that it cannot go fully outside, or if the 5DTC control module is defective and
never opens.
