Roland MP600 keyboard This was out in my garage for a couple of years. It used to work, but the sound would cut in and out. I replaced the cord, which was taped in a few places. It has power, but no sound at all. Any trouble shooting suggestions?

  • Hi, I can help. You just have a cold soldier joint on the DC power input.Get the top/bottom off by removing a few screws and expose the connector. Just take a little soldier and touch up the solder points on the connector on the board. That's it. Will be good as new.
  • I recommend doing this before that jack gets pulled a bit to hard and tears off the circuit board which then may require more than a couple soldier joint touch ups.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Regards, Tony

SOURCE: Onkyo TX-DS838 integra receiver got sound cutting off for few sec

Hello sir, there are several factors that might cause this:

  1. Low voltage. check for filter leaking capactor. defective regulator, or a burnt resistor.
  2. High voltage peak, check for the voltage output VCC.
  3. the main amplifier is defective. if it is an IC amp. replace it. if transistorized check for the pushpull driver/transistor.
Hope this helps. let me know your progress. thanks

The key sounds are flat not intune


You did not mention the model or year, but some models have a global detune setting available (read manual, download after Googling) and it is possible that has been altered from 0.0 to some other plus or minus cents. Other models of keyboards may have a tuning potentiometer on the back. If it is a very old analog synth, then any oscillator pots might need trimming and capacitors replaced (such is work for a keyboard tech).

My amp becomes distorted when I turn my keyboard up. Both the Master Volume and the CH1 volume knobs are in the middle(12 o'clock). How do I keep my amp from distorting?


You left off the one bit of info we need... however, make sure the volume control on the keyboard is around the halfway point... If it is way down, turn it up and reduce the channel volume knob some. Make sure the cable from the keyboard is an instrument rated interconnect and not one intended for speaker (usually marked as such). Make sure the keyboard AND this amp are powered from the SAME receptacle... even if you have to run an extension cord. Listen with headphones on your keyboard to make sure the sound is clean there.

I have a Roland Fantom FA76 midi keyboard. I don't have a power supply cord for it. Where it plugs into the keyboard looks just like the cord that would plug into a desktop computer, three prong female...


yes they are the same type of cords as for the specs that is statting what the internal power converter can safely use to power the devices in the appropriate modes to change the mode you need to pen the pannel and change the seitch position, the factory default is 110-117V AC, if by chance that it is set to the higher settings the only sighn would be that the fuse will keep blowing on the device or it will cut in and out.

I've recently purchased a Roland foot pedal for my casio privia px-300 keyboard. When playing a note, even though the pedal is not pressed, the note sustains. When I press the foot pedal down, it cuts...


Sorry, but Roland uses the opposite sense switch. They use normally closed where Casio requires normally open contacts. SOMETIMES one can rewire the pedal internally, but you have to be mechanically and electrically inclined to do that.

Hello- my P95 sustain pedal does not work when plugged in but the sustain works when you disconnect the cord from the back of the keyborad


This is confusing... you say "the sustain works when you disconnect the cord"? How can that happen? and doesn't work when it is plugged in.

MOST sustain pedal problems are due to people using a different pedal than the keyboard is designed to use. It is very common that someone tries to use a Roland sustain pedal on a Yamaha and oof course it doesn't work because the Roland pedal is normally closed and Yamaha usually requires a normally open contact.

A FEW keyboards now check the state of the pedal input when power is first turned on and configure the pedal polarity accordingly. For these keyboards, make sure the pedal is plugged in before power is turned on.

How do i connect my roland D5 keyboard to my pc


What kind of sound card do you have in your PC? Generally you can plug into the line in jack using a stereo RCA to 1/8" stereo plug cord with !/4" adapters on the RCA plugs. Then run from the !/4" left and right output jacks on your D5 to the !/8" line in on your sound card.

Roland keyboard. Extremely static-y speakers. Cuts out.


It sounds like your volume slider is dirty. Try carefully and judiciously spraying a good quality contact cleaner into the slider and working it. do not use a lot. It only takes a little. Also do not use WD40.

I can not work with 3 sound midi modules, roland mks80, jv2080,ak


I assume roland mks80, roland jv2080,akai s 950 are all being used with a midi interface. You must make sure you download and install the latest driver softwarefor the midi interface. You do not need drivers for the instruments you mention but you must ensure your midi cables connecting the above devices are not damaged
