Open the cover, allocate laser head Assembly outward, electrify, laser head components to smoothly slide. Since the laser head Assembly can slide back and forth, and read music, time, plays 2 minutes image description RF-signal processing, digital signal processing and servo/servo drive circuits are working properly, faults can appear in places associated with the laser head Assembly movement. Associated with them in addition to feed motor, transmission gears, slider, but is the laser head Assembly and single row 16 foot Flat Cable and plug. Unplug the ribbon cable measurements, communicated the end, check the corresponding sockets without contact. Test machine after changing a good laser head Assembly fault still, sometimes you can't read music, display 00M00. Repeated analysis continues to believe that failure could be cable connection is bad or broken. Then unplug the cable again, flatten measured, was finally diagnosed with 3 broken thread, judging failure cause that is cable.


Analysis of fault line because the line is relatively short, during use, wire bending movement prone to fatigue, to a certain extent copper breaks. When you boot, always start the laser head Assembly slides to the reset State in this line up, there is a certain tension, breakage, and everything is OK and playback laser head Assembly move away, two minutes or so, cable tension decreased broken disconnect, failure to appear.
Maintenance practices show that with the laser head connection of single line breaks caused by the symptoms vary, but it is a common failure for this machine, maintenance may wish to change to a new cable try, often r-spend less time and energy, and avoid detours.
