Common Breakdown Maintenance Of Dvd Navigation(1)
Maybe you have bought the GPS DVD Navigation for your beloved vehicle at a very low price
, for which you feel very much satisfied. Of course all the features have been well accepted by the majority of the car owners. The market has a very large possessing capacity. The quantity of brands is abundance. However, you may often come across the problems because of the high failure rate of the DVD Navigation. Generally speaking, after half a year or a few months, the following problems may happen to you like no playing of the disc, entering and ejecting of the disc, poor shockproof and other faults and poor performance. Here are some steps and experience which can help you to repair the fault machine. It is just for the reference of the beginners.
First, there is no playing of the disc. Such phenomenon makes up eighty-five percent of the amount of maintenance. Among them about 45% are caused mainly by spindle motor. More or less 45% is brought about by the break of the harness for optical pick up. (It is very difficult to judge by our own naked eyes.) The damage of the optical pickup leads to 5% of the faults of the GPS DVD Navigation. The other makes up 5%.
1. In line with the principles first easy then hard, you should have a look at the laser head and see if the laser head is clear enough. First of all, you can clean the laser head with the cotton balls filled with alcohol.
2. Put in a disc, then turn it off. Turn around the disc to feel whether it is spinning freely with no problem. (Surely it is the usual experience of a feeling.) If you feel that there is a lag or resistance, you had better change the spindle motor.
3. If the disc can spin freely and the inertia is very good, you can try to replace the harness for optical pickup with the new one.
4. After the above 3 steps, if the DVD Navigation is not able to play the disc, you can try to change the optical pickup.
5. Measure the drive power and check the power supply insurance of the drive.
Second, the DVD Navigation has poor fluency of the entering and ejecting of the disc. This phenomenon accounts for only 10%.
1. You should clean the rubber covered roller.
2. If there is no friction between the axis and the roller, you just have to wrap three rounds the axis using the transparent tape so as to increase the friction.
3. Another case is that after the disc entering the
car DVD Navigation, there is no sign of switching to the form of DVD or after the ejecting of the disc, you can not put in the disc since the motor continues to run. This phenomenon is caused by the aging of the infrared light-emitting tube. You have to change the both of them. Generally speaking, you replace it with the infrared tube of the remote control. However, it can not last for a very long time.
Third, the shockproof performance is poor. This phenomenon is generally coming together with the problems of reading slowly, choosing the disc. Clean the laser head can alleviate the problem to a certain extent. If the shock-absorbing rubber is broken, there is no doubt that you need to replace it.
Fourth, there is no sound coming out from the machine. Here what we Oem
car gps would lie to talk about is no sound in the vehicle, but it is in normal condition on the operating platform. The cause of the phenomenon is that the speaker wire is electrical ground. In this case if the machine continues running for a long time, the amplifier is easy to burn.
Fifth, there are other key panel damage, broken panel cables and so on. Because these faults are easy for us to figure out, we dont need to talk about it further.
