Vitron DVD Loading Problem

ZIC WORKSHOP In Bekasi, we often get dvd vitron with the case on loading (reading discs). Especially that use chips made by sunplus.
Here I study for the model: VITRON DVD-680, which have few complaints as follows:
Loading or reading of the old disc can occur because: optics is already weak and you can be sure to use the optical normal.Dapat also occur because of its spindle motor (disc player) is weak and not linear putarannya.Bisa also occur due to power supply regulation which is not good; elco 1000/16V to track its already menggembung.Juga 5V can occur because there is a problem in a servo system (IC CD5888) and the surrounding components.
For the case of the servo system, which used to be the cause is; supply voltage of 3.3V for the chipset is not good or drop.Contoh of this symptom is when the dvd will spin and just a few minutes, after which the error or even a panel of buttons did not work (hangs / jam).
This damage often occurs in the components: the elco 220/10v - two diode IN4002 (modifier from 5v to 3.3v) or if not use a diode, the IC LD 117-3.3 - two servo transistor TR: S8550.
If you observe during the process there are two transistors in the heat, then immediately replace a few components that I mentioned above.

If you observe the laser optics is not lit, check the voltage of 3.3 V for line pre-amp IC OPTICAL, usually the cause is choke SMD (L) or FUSE or R smd smd (usually written: 000) also check the two SMD transistor for optical laser drivers.
In case you check the servo IC R-value smd 330 and 470, it often changes its value because the heat makes frequent errors or freezes in the middle of the road.
The last and also very often happens is that causes damage to the optical memory can not translate the data, sometimes only want dvd just only vcd or mp3 or any, for this case the only way is to replace its EEPROM (memory: EN25f80). Unfortunately This memory is very difficult to get and you should be diligent, diligently copying the memory of which still normal dvd for backup if you get a case in memory.
Some cases in memory that is; NO disc, cliched images, picture boxes, only displays the brand image, sound disabled, the function keys, etc. error reply.
IC chipsets too (sunplus) can cause no disc damage, the symptoms are if you observe and grasp this IC and the heat is not normal (high) IC is damaged.
Hopefully this discussion can be a little help, especially for the brother Aditya who has sent questions, and fatherly all I say many thanks.


ZIC WORKSHOP in Bekasi, We Often get the dvd once vitron with the case on the loading (read disc). Specifically I use the chips made sunplus.
Here, I study for the model: VITRON DVD-680, the which has Some concerns as follows:
Loading or reading a disc-May occur Because: optics are weak and you cans check by using the optical normal.Dapat I Also Happen Because of its spindle motor (disc player) is weak and not linear. Can Also occur due to power supply regulation That is not good; elco 1000/16V to 5V line is LEAK.Juga cans occur Because there is a problem in the system Servo (IC CD5888) and the Surrounding components.
For cases in servo systems, the which is to be the cause is; 3.3V supply voltage for the chipset is not good or symptoms of this drop.Contoh Pls is the dvd and Would like to rotate just a Few minutes only, after That error, or even the button panel is not working (hang / misfire).
Often this damage occurs on the components: elco 220/10v - two diode IN4002 (modifier from 5V to 3.3V) or if not wearing a diode, the IC LD 117-3.3 - two transistor TR Servo: S8550.
If you observed During the two transistors is hot, then Immediately change the number of components That I mentioned above.

If you Observe the optical laser does not work, check the voltage v 3.3 channels for pre-amp IC OPTICAL, it is usually chokes SMD (L) or FUSE or smd smd R (regular written: 000) Also check the two drivers SMD transistor for laser optics.
In the case of the IC Also check your servo R smd valued 330 and 470, this value is changed frequently Because of the heat Often error or traffic jams in the middle of the road.
The last and very Also Happens Often Is That the damage to the optical memory cans not translate the data, Sometimes only dvd or vcd or mp3 course, for this case the only way is to replace its EEPROM (memory: EN25f80). Unfortunately it is very Difficult This memory and you must be Diligent diligently to-memory copy of the dvd you are still normal for backups if you get a case in memory.
Some cases in the memory; NO disc, negative image, checker, only displays the image, voice disability, function keys etc. I error.
IC chipset is (sunplus) cans cause no damage to the disc, if your symptoms are observed and hold the IC and the heat is not normal (high), this IC is Damaged.
Hopefully this discussion cans be a little help, especially for relatives WHO have Adit send a question, and all I say many thanks.
