The monsoon season is over, but only a few will need to be repaired because of the tide. The optical lens is easily obscured by the tide of home-based disc machines, resulting in laser beams not picking up signals normally. It should be noted that when the climate is dizziness or the cold and heat changes, it produces drops or mists inside the machine, which should be used with a dvd preheating for a few minutes before the disk is placed。
Why don't you read dvds
1. Optical causes of disks
1. The skin of the disc, which has dust to wipe out, is dirty. Blank is broken. Same-sized head。
2. Laser head reading disks are weak: the reason is normal ageing, the laser head is dirty, etc. The laser head can be cleaned with a washing disk。
2. Disk reasons
1. Dust and heavy wear and tear, and new discs
2. Discs are not on the right track, instead of dvds。
Poor quality of cd-roms. The reason for this is the poor quality of some of the empty cds themselves (many cds in the country are of poor quality), the dvds that have been carved on such cds, and the inability of many machines to read them
At the same time, at the time of writing, the quality of the cd-rom is also affected by the high rate of selection。
So, at the time of writing, the speed of selection is fine (or a simulation can be made, then a data entry can be made, so twice
The 3-dvd camera is damaged. The main plate is broken
If the laser head is weak in reading disks, it is even more difficult to read cds。
What do you do with the cds
If there is a non-read film on the disc, it may be that the laser head is unclean or that it is old. How can these two situations be effectively avoided? If the disc is not used for long periods of time, it is also subject to occasional electrical access, especially in a damp environment where it is more frequently used to prevent the damp and exposed laser head. And it's best to cut the power when you don't use it. The dvd, in particular, is generally on standby without cutting off the power, which is not only costly but also dangerous. In addition, many people take the disk out when they're done with it, so let's just say that it's better to be lazy, not to take it out, because it's supposed to block the dust and protect the laser head. In the case of dust removal, electric wind (cool blowing) or vacuum cleaners, etc., should be used in the shut-down state, but not frequently to remove dust from shredders。
The laser head is usually cleaned with a washing disk, but it is better to use it less, because there are so many stings on the dish that the coating of the laser head will be worn out and the ageing of the laser head will be accelerated by more use. In addition, cleaning fluids are used less. If it is indeed dirty, wash the laser head with a cotton sticker, and remember not to use alcohol when scrubbing。
No consecutive suspensions and long pauses, since when the suspensions appear to have stopped, the laser head is still in working condition and the constant suspensions accelerate the ageing of the laser head。
Do not use pirate disks. Most pirated discs are of poor quality and are used to overload laser devices, which not only reduce their lifetime but also make them highly vulnerable to damage。
How do you fix the disk without reading it
When the non-referral dvds are not read, the first check is whether the discs are turned around, or whether there is a 2r2 or 4r7 on the side of 5954, and if the circuit is changed, the main axis is likely to be in trouble if the speed of the circuit does not reach it and the engine is hot enough to touch it. The main axle electric resistance value is measured on a universal scale, and all of the damage is judged to be damage eight times or more, the performance of eight euros or more, the emergency maintenance can be cleaned with aqueous ethanol, and around 8v voltage is inverted, but it is preferable to replace the main axle electric generator for a short period of time (one month) with short circuits for the main axle, normally 12 euros for the dvd light head, with only the screws on the side of the main axle, without the seal, otherwise to change the focal height of the light, resulting in a read-only dvd or a read-only vcd. It's also very easy to break bare-headed lines, and better to change them。
Maintenance point of the disc
1. Place it in the cooler ventilator as far as possible, not in direct sunlight or near heat sources。
2. The laser head of the disc is defiled and is not placed in dusty areas, especially in working conditions。
3. Do not be placed on the same side as the high power speaker。
4. It would be better to cut the power if the disc was not used for a long time。
