The Technics RS-TR515 is a dual cassette deck manufactured by one of the most well-known names in consumer electronics. While CDs are the industry standard for recorded music, many stereo owners maintain cassette decks in their equipment collection. Over time, cassette decks start to develop problems. A professional technician can repair the cassette deck, but the repair cost will often be greater than the value of the cassette deck. Use some basic professional techniques to troubleshoot problems.

Test the cassette deck's power. Plug the cassette deck into another wall outlet to eliminate the outlet as the cause of the problem. Gently shake the power cord after turning the deck on to determine whether or not the power cord is faulty. Turn the power off and remove the power cord from the outlet before continuing.
Check the fuse. When electrical devices suddenly stop working, an electrical surge could be the problem. A fuse is wired into the deck's electrical system to prevent a power surge from destroying the system's delicate electronics. Unscrew the fuse cover. Carefully remove the fuse. Hold it up to the light and check to see if the metal strip that runs down the centre of the fuse is burnt. Do not replace it until the rest of the deck has been examined for the cause of the blown fuse.
Open the deck's case. Use a Phillips screwdriver to remove the screws that hold the case onto the deck's frame. Place the screws into a container to avoid losing them. Carefully lift the casing off of the deck's frame.
Inspect the electronics. Look for burnt circuitry and corrosion on the electronic components within the deck. Examine the wiring, looking for loose, crimped and broken wires.
Check the deck's belts. The deck uses a motor and rubber belts to move the cassette's tape across the tape heads. Over time, the belts start to stretch and wear out. Use a finger to test the belt tightness. The belt will be taut and resistant to stretching if it is not worn out. Look for cracks in the rubber, which is also a sign of belt wear.
Check the deck's mechanical parts. Plug the deck's power cord into an outlet and turn the deck on. Press the "Play" button. With the case still off, watch the deck's mechanical system as the "Play" button is pushed. The deck's mechanical system should smoothly engage, playing the cassette without trouble. Check the "Rewind," "Fast Forward," "Stop," "Pause" and "Record" buttons as well.
Tighten any loose mounting screws. Many of decks mechanical parts, such as motor and gear's mounts will become loose over time. This creates an alignment problem which causes the playback system to fail. Use a Phillips screwdriver to tighten any loose screws.
