No power There is no power to my piano. I have changed the power lead as there was a break in the wire. It's still not working. Please help!

Lose up the power button

If certain notes on your Technics SX-PR150 digital piano are playing at a lower volume than others, it's possible that there could be a few underlying reasons for this issue. Here are some steps you can take to troubleshoot and potentially resolve the problem:

1. Dust and Debris:
   • Check if there is any dust, debris, or foreign objects present around the keys and internal components. Dust or debris could affect the key's action and cause uneven volume levels.
2. Contact Cleaning:
   • If you're comfortable doing so, you can carefully open the piano and clean the contacts underneath the affected keys. Contacts that have accumulated dirt or oxidation might lead to volume inconsistencies. Use a clean, dry cloth or contact cleaner specifically designed for electronics.
3. Key Mechanism:
   • Inspect the key mechanism for any signs of physical damage, misalignment, or wear. Damaged or misaligned keys could lead to uneven volume levels.
4. Sensors and Sensors Board:
   • Digital pianos like the Technics SX-PR150 use sensors to detect key presses and control volume. If a sensor is malfunctioning or damaged, it could result in volume inconsistencies. Check the sensors and their connections for any issues.
5. Audio Output and Amplification:
   • Check if the issue is specific to the internal speakers or if it also occurs when using headphones or external amplification. If the issue is present across all audio outputs, it might be related to the piano's internal components.
6. Factory Reset:
   • Perform a factory reset on the piano to restore its settings to default. This can help rule out any software-related issues that might be affecting the volume levels.
7. Professional Inspection:
   • If the above steps do not resolve the issue, it's recommended to seek the assistance of a professional technician who is experienced in repairing digital pianos. They can diagnose the problem accurately and perform any necessary repairs.

Please exercise caution while performing any internal inspections or repairs on your digital piano, especially if you're not experienced in working with electronic equipment. If you're unsure or uncomfortable with the process, it's best to seek professional help to avoid causing further damage.

Hi,

Please ensure that the volume down button isn't permanently stuck on the piano. You can also double check that there's not wire plugged into the earphone jack otherwise all of you sound might be outputting to that wire which might lead to headphones that you're not necessarily using. Then, you can power cycle your device before checking for sound again. Otherwise, you might have to get the device repaired at a location like Geeksquad/Bestbuy.

Thank you.

Is the unit operated directly from the mains or via a mains adaptor (transformer) If it is the later then my guess is that the socket owhere you plug the power adaptor in is loose. They have a habit of breaking away from the circuit board. When you then move the keyboard it breaks the connection . You can test this theory by turning it on, looking at display or light that is on, move the plug and see if it cuts out. If it does the fault is here. Replace the socket and if needed repair pcb as pads tend to break away from board.


If it is mains operated or power socket is OK then it could be loose cables or a break on the PCB. The socket option is the more likely.


If you need more specific info on your keyboard please state make and model and request further info under this topic.

The Roland RD-600 is a digital piano, and its hammer action mechanism is designed to simulate the feel of an acoustic piano. The hammers in digital pianos like the RD-600 are typically made of materials like plastic or a combination of materials to replicate the weighted feel of acoustic piano keys.
The breaking of hammers in a digital piano is not a common issue, and it's not typically related to the age of the instrument alone. Several factors could contribute to the breakage of hammers, and it's essential to consider the following possibilities:

1. Excessive Force: If the keys are played with excessive force or if there's any physical damage to the instrument, it could lead to the breakage of hammers.
2. Material Quality: The quality of materials used in the construction of the hammers can impact their durability. If the hammers are made from subpar materials, they may be more prone to breaking.
3. Manufacturing Defects: In some cases, there could be manufacturing defects that make the hammers more susceptible to breakage.
4. Maintenance: Lack of proper maintenance, such as cleaning and regular inspection, may contribute to the wear and tear of components, including hammers.

If you've observed a pattern of hammers breaking with regularity, it might be worth investigating the specific cause. If it's due to excessive force or physical damage, adjusting playing habits and taking care during transport can help mitigate the issue.
As for whether it's worth purchasing new hammers from Roland, it depends on the extent of the damage and the overall condition of the instrument. If the RD-600 is in good condition otherwise and you enjoy playing it, replacing the hammers could be a reasonable option. However, you may want to assess the cost of replacement hammers compared to the overall value of the instrument, factoring in the cost of a used RD-600 and any potential future maintenance needs.

What adapters have you tried? The P85 REQUIRES a 12 VAC adapter, NOT the common DC type and it needs a 1.5 amp (1500 ma) type adapter. If you connected a DC adapter it will NOT do damage, the unit just won't work. You can find adpaters on Ebay or Google search.

I could not find the schematic for this, but other Casio units use a common voltage regulator amplifier chip to drive the speaker... I would firsst check that leads to the speaker have not become disconnected.

1000 Watts? Well, those are peak values. !000 watts RMS into a 12 inch speaker and it would smoke... this is some of our inflated advertising. But that is beside rhe point... now on to your problem: What you are having is a ground loop. You may have to do more than one thing to correct this here is the things to do in the order to do them to solve the problem:

1. Connect the piano and the speaker to the SAME power source or receptacle, even if you have to run an extension cord, three wire of course. Plug all of this ONLY into a grounded outlet, if your house has only two wire plugs, then you need to get an electrician to install a grounded receptacle.

2. Use Balanced lines. This means XLR or TRS balanced cables between the piano and the speaker. Use the 1/4 inch jacks output, not the RCA ones.

3. Since the AUX outputs do not support balanced lines, the next step require you use DI box. They are about $20 from Guitar Center and others. With very short 1/4 inch mono cable connect the piano to the DI box from the L/R mono piano to the high impedance input port of the DI and set the ground lift switch to "LIFT". Use an XLR to XLR cable from the DI box to the speaker. This last step if needed is the last thing in our bag of tricks to break the ground loop that can cause the buzz. Dirty power, if you have lamp dimmers can be a source of the noise.
