1, Transmission belt aging caused by the CD-ROM
When such a failure occurs, the optical drive generally shows that the door is not fluent in and out, the disc does not rotate. All you need to do is open the outer box of the optical drive and the fault is clear. The reason is because of the transmission belt aging caused the warehouse door in and out of weakness and not fully entered, so that the bald head and spindle motor are not fully up to the place, so that the CD-ROM drive does not know the disc. You just need to replace it with the same type of new belt. When the same model can not find the transmission belt, according to the extent of the transmission belt aging with scissors to cut a small paragraph after the use of 502 glue can be bonded.
2, the bald data transmission line caused by poor contact does not know the disc
When such a failure occurs, the bald-headed focus is not able to know the disc. Performance for the bald head sometimes will not be reset, sometimes only move up and down without transverse movement, sometimes the opposite, sometimes even do not shine and spindle motor does not move, often give some users are bald burning or spindle motor, drive block the illusion of the problem, it is easy to cause unnecessary losses. Therefore, when you have such a failure in the optical drive, you must first look at the bald data transmission line is intact, and then check the bald or other things. The solution to this type of failure is generally to replace the same model of the data cable, but for those with only one active data transmission line is not. The following is a method for readers to refer to: When a data line with an activity is not good, first find the break point, at both ends of the breakpoint with a knife carefully scraping the paint on the soft printed board, and then carefully welded with fine copper wire, and finally with glue to seal on it again.
