What You'll Learn
Reset your Technics piano
Resetting your Technics piano can be a useful first step in repairing it. Technics pianos do not require servicing, only repairs when something goes wrong.
- If the sostenuto pedal or soft pedal are not working properly, turn off the keyboard or piano and turn it back on. This will reprogram them to their original settings.
- If the rhythm won't start, check that the "Rhythm Volume" and the "Drums" volume are set to an appropriate level. If it still doesn't work, you may have selected a rhythm from "Composer Memory" that has no stored pattern. Try selecting a different rhythm.
- If unwanted percussive sounds are being played, make sure the "Keyboard Perc" button is turned off in the "Sound Group" section.
- If you are not able to select other sounds, the "General Midi" status may be preventing you from changing some sounds in order to produce a generic midi sound. Under the "Common Settings" menu, turn this status to off.
- If the sustain pedal is not working, first check that the pedal cord is firmly connected to the "Pedal In" terminal on the back of your keyboard. Also, check that the "Sustain Pedal" button on your keyboard is turned on.
- While pressing the three lower left buttons in "Rhythm Group" (these buttons are "Soul & Disco," "Gospel & Blues," and "Country and Western"), turn the power button on again. This will reset all functions to their factory settings.
- If your model has a metronome button, try holding this down while turning the piano on.
- While pressing the three lower-left buttons in the RHYTHM GROUP (Rock, Funk/Fusion, Trad Dance) at the same time, turn the piano on.
If none of these steps work, you may need to repair your piano. It is recommended that you speak to a professional repair service to diagnose and fix the problem.

Check the sustain pedal isn't connected to the Pedal In terminal
If your Technics electric piano's sustain pedal is not working, there are a few things you can check. First, make sure that the pedal cord is firmly connected to the "Pedal In" terminal on the back of your keyboard. Check that the "Sustain Pedal" button on your keyboard is turned on. If the sustain pedal does not produce a consistent tone, it may be a faulty pedal.
If the sustain pedal is not working consistently, the problem could be with the pedal itself. Check to see if the small switch in the pedal is sticking and needs to be freed up. You can also try re-assigning the soft pedal to sustain through the menu. If the pedal is acting like a switch, where one press activates the sustain and another press releases it, make sure that "momentary behaviour" is selected in the "Edit" tab.
If you have tried all these steps and the sustain pedal is still not working, there are a few more things you can try. Check that your sustain pedal is assigned in the MainStage “Layout" tab. Also, make sure that the “Type:" is set to “Press / Release", and the “Send Value to:” is set to “None." Check to make sure your sustain pedal is plugged into the correct port on the keyboard controller. If the sustain pedal is inverted (functioning backwards), check to see if it has a polarity switch (this may be located underneath the pedal), and if so, flip the switch.

Reprogram the soft and sostenuto pedals
If the soft and sostenuto pedals on your Technics electric piano are not working properly, the first step is to turn off the keyboard or piano and turn it back on. This simple step can reprogram the pedals to their original settings, as different sounds can be produced using these pedals.
If the issue persists, check that the pedal cord is firmly connected to the "Pedal In" terminal on the back of your keyboard. Take great care when re-connecting the pedal lead and ensure that it is the right way round. Do not force it, or the pins will bend. If you own an older model of the Technics piano, the 8-pin mini DIN pedal cables are no longer available. Replacements are very expensive as they have to be handmade. They also need to be soldered and cannot be plugged into the pedal unit. However, the 4-pin mini DIN pedal cables are available for newer models and can be plugged into the pedal unit.
If the sustain pedal is still not working, check that the "Sustain Pedal" button on your keyboard is turned on. You can also try resetting your Technics keyboard or piano. While pressing the three lower left buttons in "Rhythm Group" ("Soul & Disco," "Gospel & Blues," and "Country and Western"), turn the power button on again. This will reset all functions to their factory settings.
The sostenuto pedal allows you to sustain certain notes while others remain distinct. The soft pedal, also known as the una corda (Italian for "one string") pedal, shifts the whole action slightly to the right on a grand piano. This makes the hammers strike only two of three strings, resulting in a darker, softer sound.

Check the volume settings
If you are experiencing issues with the volume on your Technics electric piano, there are a few things you can try before seeking professional repair services.
First, ensure that the piano is turned on and that the volume settings are properly adjusted. Check that the "Rhythm Volume" and the "Drums" volume are set to an appropriate level. If you are using a Technics SX-PR603 piano, you can adjust the volume settings on the control panel.
If your piano is not producing any sound, try turning it off and on again, as this can reprogram the instrument to its original settings. You can also try different sounds using the sostenuto and soft pedals. If your piano has been in storage or not used for a while, it may need to be reset to its factory settings.
For example, to reset a Technics PR270 electric piano to its factory settings, turn off the power, press and hold the three lower left buttons in the "Rhythm Group" ("Soul & Disco," "Gospel & Blues," and "Country and Western"), and then turn the power on again while continuing to hold the buttons.
If your piano still has volume issues, it may be time to consult a professional repair service. When seeking repairs, always provide the model number of your piano and a detailed description of the issue, including any relevant symptoms and previous repair history.

Check for corrosion
Corrosion is a common issue with electric pianos, and it can significantly impact their functionality. It is usually caused by drink spillages, long-term exposure to salty or humid environments, chemical leakage from a component on a circuit board, damage during transit, rough handling, or a poor previous repair attempt. Corrosion can cause unexpected issues and increase repair costs, so it is important to address it promptly.
To check for corrosion in your Technics electric piano, start by locating the circuit board. This is usually found underneath the piano's top panel. Before proceeding, ensure that the piano is unplugged and that you are working on a static-free surface to avoid damaging the electronic components.
Once you have accessed the circuit board, carefully inspect it for any signs of corrosion or damage. Corrosion often appears as a greenish or white powdery substance on the board or its components. Pay close attention to the areas around connectors, chips, and capacitors, as these are prone to corrosion.
If you notice any corrosion or damage, it is important to clean it carefully. You can use a soft brush or cotton swab dipped in isopropyl alcohol or a specialised electronic cleaning solution to gently remove any corrosion buildup. Ensure that you do not apply too much liquid, as you want to avoid getting liquid into areas where it could cause further damage.
After cleaning, let the circuit board dry completely before reassembling the piano. It is important to address corrosion as soon as it is detected to prevent further damage and ensure the optimal performance of your Technics electric piano.
