Why can t my tape recorder read the disc, there is a creaking sound when the disc is turning, and th

The preliminary judgment is that the bald head is broken.

Hello, I am glad to serve you and give you the following answers: If there is sound on only one side of the disc player, the main reason is that there is a problem with the audio circuit of the disc player, or there is a problem with the audio output interface of the disc player. The workaround and practice steps are as follows:

1.Check the audio circuit of the disc player to make sure that the circuit is not damaged, there is no open circuit, and there are no problems such as poor contact. 2.

Check or macro check the audio output interface of the disc player to ensure that the interface is not damaged, there is no open circuit, no bad contact and other problems. 3.If there is no problem with the audio circuit and interface of the disc player, you can try to replace the disc drive to ensure that there is no problem with the disc drive itself.

4.If the above steps do not solve the problem, you can try to replace the audio cable or the audio output interface to ensure that there is no problem with the audio line and interface of the disc player. Personal Tips:

When using the disc player, you should pay attention to protect the audio line and interface of the disc player to avoid damage or disconnection, so as to avoid the situation that there is only one side of the sound.

1. Eliminate the noise of the power supply fan.

Power supply fan noise is generally divided into rotational noise and vibration noise. Rotational noise is generally caused by a lack of lubrication in the fan bearings. The solution is to apply a few drops of sewing oil to the fan bearing.

Vibration noise is generally caused by unbalanced fan blades, loose blades on the shaft, and excessive bearing clearance. If it is the accumulation of dirt on individual leaves, it can be removed in time; If the fan blades are missing, asymmetrical, or the bearing clearance is too large, it is best to replace the power supply fan with a new one.

2. Eliminate CPU fan noise.

The bearings and blades of the CPU fan are the most likely places to cause noise, and after long-term use, the bearings of the fan may have too much friction due to lack of oil, resulting in large noise, so you can add some sewing oil to the fan shaft. The specific operation is to carefully uncover the label on the fan shaft, add oil and then cover it. If the quality of the fan blades is not very good, after a period of rotation, the fan blades may be deformed due to heating, touch the inner wall, and make noise.

The solution is to take the blade and gently scrape the scratch a few times to increase the distance between the fan blade and the inner wall to avoid friction between the two.

3. Eliminate hard disk noise.

The noise of the hard disk may come from its own vibration, and at this time, it is not just as simple as making annoying noise, but also involves the safety of the hard disk. Because the vibration caused by improper installation may damage the hard drive, the drive installed horizontally must be parallel to the chassis, and the vertically mounted hard disk must be perpendicular to the bottom surface of the chassis and not skewed. The most important thing is that the hard drive must be in a stable state (it is recommended to use more than three screws to fix the hard drive), but at the same time, it is important to make sure that the set screws of the hard drive are not too long or too tight to prevent damage to the circuit board and platter.

4. Eliminate chassis vibration noise.

In order to eliminate the vibration noise of the case, we can pay attention to the hardness of the case and the connection between the case and the cabinet when purchasing a computer. Chassis with materials that are too thin and use too "economically" are not strong. Gently squeeze or twist the box by hand to check whether its hardness is acceptable.

A case with a screw-on lid and body is more stable, while a screw-free case is prone to vibration, so it's best to consider it when buying. In addition, some appropriate shock absorption measures can be taken during installation and use, such as attaching a 3 4 mm thick plastic foam strip to the parts of the box lid that are in direct contact with the box body, and then tightening the box cover.

It has to do with the base of the disc. Chip-based eccentricity is more prone to this problem; In addition, this problem can also occur when the disc is deformed.
