If the Nokia 6300 microphone does not work, then you should first determine the reason. In general, phone repair does not require any special skills. However, you should be able to work with a multimeter to ring paths.

Perhaps this is the basic skills. Often the essence of the search for a problem lies precisely in the search for breaks. As a rule, breakage occurs mainly due to mechanical damage. Especially if the phone has been in the water.

Nokia 6300 Microphone Repair

Often the problem lies precisely in the breakage of one of the signal lines. The measuring device will reveal this defect. Accordingly, it can be eliminated. Of course, it would also be nice to have a diagram at hand.

Fortunately, the schematic diagram of the phones of old models can be found on the web. It is important to be able to read electrical circuits here. But, the basics of this could be learned at school, in physics lessons. You can also ask online about this issue.

It is also desirable to be able to work with a soldering iron to restore broken contacts if necessary. So, you will need a soldering iron, multimeter, flux, tin and tweezers to work.

Nokia microphone repair – algorithm of actions:

• First you need to check the microphone for serviceability – you need to ring the path with a multimeter.
• If there is a breakage, then the contact must be restored using a soldering iron.
• To restore contact, you can throw a jumper.
• Important – the glass chip (R2100) should be checked.
• If necessary, the glass chip (R2100) can be replaced with a 2k2 resistor.
• In the absence of breaks, the RETU chip must be replaced.

This is the end of the work. It should be noted that these actions can be performed by almost any user who is familiar with a soldering iron and a multimeter.

And finally, most bb5-type phones are equipped with such a R2100 glass chip. Previously, the method of replacing the chip with jumpers and resistors was used. However, it doesn’t make sense now.

Since you can freely purchase the item in the online store. Thus, Nokia phone repair is significantly simplified. It is enough just to purchase the necessary chip and solder it. But, this will require a hair dryer soldering iron.

It is best to use new spare parts. And not to remove them from old devices. By the way, if you are interested in repairing cell phones, then you can find additional information on our website.
