Replacing the cassette belt in a Sony MHC-NX1 mini system requires a few steps. Here's a general guide to help you replace the cassette belt:
Unplug the power cord from the mini system.
Remove the screws on the side and back of the unit to access the cassette deck mechanism.
Carefully remove the cassette deck mechanism from the main unit.
Locate the cassette belt around the flywheel and capstan motor. The belt may be broken or loose.
Remove the old belt from the flywheel and capstan motor.
Install the new belt around the flywheel and capstan motor.
Reassemble the cassette deck mechanism and main unit, making sure all screws are securely fastened.
Plug the power cord back into the mini system and test the cassette deck to ensure it's working correctly.
Note: The exact steps to replace the cassette belt may vary slightly depending on the specific model of your Sony MHC-NX1 mini system. It's always a good idea to consult the user manual or seek professional assistance if you're unsure about the process.

Replacing the cassette belt in a Sony MHC-NX1 mini system requires the following steps:
1. Turn off the power and unplug the mini system from the electrical outlet.
2. Remove the screws that hold the top cover of the mini system in place with the help of a screwdriver.

5. Clean the pulleys and gears in the cassette deck mechanism with a clean cloth to ensure they are free from debris and dirt.
6. Take the new cassette belt and place it onto the pulleys and gears in the cassette deck mechanism. It should fit snugly.
7. Put the top cover back on and secure it in place with the screws.
8. Plug the mini system back into the power outlet. Once you have completed these steps, turn on the mini system and test the cassette player to ensure that the new belt is functioning properly.
