What if the stereo is wet?

Question 1: What should I do if my computer stereo is wet? The stereo is a high-power electrical appliance, so there are many air holes in the fuselage. Besides a lot of dust will enter after a long time, moisture will also have different degrees of influence on circuit components. The best treatment method is to blow out the moisture inside the equipment with a hair dryer. Secondly, we can consider keeping the equipment in standby state, and proper heat will also dry the circuit part. But standby is standby. If it rains, don't forget to unplug the bolt. In addition, the dehumidification function of the air conditioner can be turned on to achieve the purpose of maintaining electrical appliances.

Question 2: What if the speaker gets wet? 5 points is not the cause of getting wet, but the carbon film in the knob potentiometer is aging, or the knob is rubbed.

You can unplug the knob and turn it to see if there is any noise. If there is noise, it means that the carbon film is aging, so we can only disassemble the machine and replace the corresponding potentiometer.

Question 3: What should I do if the stereo is wet and already noisy? There is noise because the audio signal circuit is disturbed by moisture and leakage. Disassemble the stereo, clean the circuit board with anhydrous alcohol, and then blow dry with a hair dryer. Pay attention to see if the filter capacitor of the power supply is oxidized. If there is something wrong with the filter capacitor, it will form a whining noise.

Question 4: What should I do if the speaker makes noise due to humidity? Put the speaker in a ventilated and dry place to dry.

Please accept it, thank you!

Question 5: The speaker has been useless for a long time, the sound is very small and there is noise, and the speaker of the speaker is wet. What should I do? First of all, has your amplifier been useless for a long time? If so, clean the amplifier potentiometer. Then clean up and replace all connection points, signal lines and connecting lines. Are there any solder joints? Clean the dust. Blow cold air with a hair dryer when it is wet. When you are finished, turn down the sound. Take some time to use it normally.

Question 6: What should I do if I install a stereo when the basement is wet? The speaker unit will be moldy, and the power amplifier circuit will regain moisture, resulting in ignition damage.

It is suggested that the humidity should not exceed 85% by dehumidification.

Question 7: I removed several speakers, and the speakers were all wet and noisy. What should I do? Wet, we will see the tide at that position, and we will see whether there are deformed elastic waves. The weakness of heart murmur is friction ring or spider. When you first observe the deformation and sinking of the wave shell, you will sink a uniform conical lifter to get the hot air from the blower. If there are no other problems, we can fix it.

Question 8: Will wet weather affect the speaker? Wet weather has a certain influence on the speaker. The analysis is as follows:

1. When the weather is wet, the ambient temperature around the speaker is relatively high. After the electronic components in the speaker are wetted, the pins may rust and short circuit, resulting in damage to the speaker.

2. When the weather is wet, the dust accumulated in the speaker can be turned into paste by water vapor, which enhances the conductivity of the dust and sometimes causes short circuit and damages the speaker.

3. After the electronic components of the sound box are damp, some circuits can't work normally, resulting in chirp. After a long time, the components burned out, resulting in the speaker not working.

4. Try to put the speaker in a well-ventilated place and turn it on frequently.

Question 9: Crown Audio Amplifier can't be used due to damp. How should I fix it? If you don't use it for a long time, it's oxidation-poor contact. I need to take it to the repair shop to check what the problem is.
