Learn how to replace resistors in a Sony stereo receiver to repair your own audio equipment. If your receiver is no longer under warranty, it may be more cost effective to perform your own repairs. The cost of shipping the components back and forth, along with paying for the actual repair may be cost prohibitive.
Here are the supplies you will need to replace your own resistors:
- Soldering iron with a solder spool
- Ohmmeter (multimeter)
- New resistor (can be purchased from your local Radio Shack store)
- Screwdrivers, pliers or tweezersSchematic wiring diagram (optional)
- Check the warranty status for the stereo receiver. Verify that the Sony receiver is no longer under warranty before you begin working on the unit. If you attempt to open a unit which is currently under warranty, Sony will void the warranty.
- Unplug the unit, and remove the outer case. Use extreme caution when you are working with sensitive electronic equipment. Make sure you do not accidentally touch other parts on the circuit boards. If you accidentally discharge current from a capacitor, you can cause serious physical harm.
- Remove the old resistor. Verify that the resistor is worn, by checking the tolerance with a multimeter. Use the soldering gun to melt away the existing solder to remove the current resistor. Once the solder is melted remove the defective resistor in your Sony receiver.
- Install and solder the new resistor. Place the new resistor onto the circuit board. If necessary, trim away the excess lead material from the new resistor before soldering. Make sure you are in a well-ventilated area, and avoid breathing in the fumes from the soldering iron. Be sure not to drip solder accidentally onto the circuit board, as that can cause electrical short circuits.
- Tin the soldering iron tip. To tin the soldering iron, melt a small amount of solder directly onto the soldering iron tip. Remove any excess solder from the tip, and place the tip directly onto the circuit board.
- Solder the physical joint. The soldering iron tip should be in direct physical contact with the joint. Use the tip to warm the area. Use the solder spool, and melt a small amount of solder directly onto the joint. The solder should not touch the physical tip of the iron. The solder should be melted directly onto the area between the resistor lead and printed circuit board.
- Test your receiver. Replace the cabinet, and test your Sony receiver. If the new resistor was installed correctly, your Sony receiver should now work.
