Some Tips for Repairing Audio Components
If you are skilled with using a soldering iron then chances are that you can repair much of your audio gear yourself. So if something breaks you don’t have to take it back to the dealer if the warranty has expired. They would most likely charged horrendous fees for repairing the equipment. Instead, you can try to fix it yourself. However, only attempt this once the warranty has expired. I would keep all of your receipts from purchasing the equipment so that you can always check whether the equipment still has warranty or not.
If you don’t have to receipt then you might want to check if there any stickers applied on the equipment itself which would indicate the date of purchase. Typically manufacturers offer one year warrantee. Within that warrantee you can get your equipment repair or replace free of charge. If you are afraid of your equipment breaking after the warranty has expired, you can also purchase the extended warranty. This type of warranty is typically offered by electronic retailers. However, low-voltage equipment typically doesn’t break for several years so purchasing an extended warranty often doesn’t make sense.
If the warranty indeed has expired then it is time for you to troubleshoot the problem and if necessary fix it. First of all, before you attempt any repair, make sure that your equipment is not connected to power. Once the power cord is detached from the outlet, you can open the enclosure. Once you look inside your equipment, you can often figure out what the problem is because faulty components will usually show black spots. Once you determine which component is faulty, you will have to purchase a replacement which has similar specifications.
Instead of swapping individual components, you can also swap the whole assembly. Just note the serial number and the name of the assembly and then contact the manufacturer or your retailer in order to purchase a replacement. Purchasing a replacement and assembling it yourself is usually a lot cheaper than having your retailer do it for you. They typically charge fairly high for labor and so you can save a bundle by doing the labor yourself.
Some problems might be as easy as replacing the power fuse. You can inspect the fuse after you remove it and see if the wire inside the fuse has melted. If that is the case then you can replace the fuse with another one and check if the equipment works. Some components also have fuses on the inside so you would actually have to be sold the fuse in order to replace it with a similar fuse. However, note that if there’s something wrong with your equipment then replacing the fuse might not solve the issue. So before inserting a new fuse I recommend checking the circuit boards for any obvious damage.
