That is BS. First verify your power source. Any leaking is probably an electrolytic cap on the board. May require a bit of cleanup. Take it to a competent electronic repair shop. You can open the unit and look for something out of place. The electrolytic caps are USUALLY in a round can with plastic over them and woul likely be about 1/2 inch in diameter say and 3/4 inch tall for the power supply area.

The record button on my DR-670 Dr. Rhythm drum machine no longer works, it has benn sitting for quite a while . It has been well protected in it's original packaging. Any help would be appreciated


YOu can disassemble the machine and clean the switch and resolver the connections to the circuit board, but it would be easier to call Roland and get the info for the nearest service center in your area.

I'm having trouble being able to select any of my sounds or switch octaves or keys on my Roland RS-50 it seems as if it's stuck.... What do you think I should do


Will probably need to be diassembled and cleaned. Either a sticking key or a compromised contact on the circuit board. Any electronics repair shop should be able to fix this.

I got a roland jx-1 keyboard with no power supply. i tried radio shack power supply (12v - 500ma) as mentioned at the back of the keyboard and i was able to turn it on but couldn't hear any sounds..plz...


search google for "JX-1 FACTORY RESET". If that does not help, try your headphones. If that neither, you blew the Audio Power Amp circuit. Take it to a Tech. Good luck !!

Roland EP50 F sharp does'nt work.All other keys are fine


EP-50's are notorious for problems with either the 4.65 voltage feed to the velocity sensitive keys or failure of the small zenner diaodes. Each key has a pair fo split circles on the circuit board under it. When you hit the key you connect each side of the circles and the harder you hit the keys the quicker the circuits close the louder the sound. Problem is if the voltage to either circle fails, due to bad solder, scratch on circuit board, failed diaode then the sound disappears. The fix is simple if you are knowledgeable on solder on circuit boards, can use a multimeter and can dissassemble and reassemble the keyboard. If you have to take it to a repair shop it is probably not worth fixing as this is not one of the better Roland products

Roland XP 50 Head phone not working


Make sure that the level of the headphone out put is open. Make sure it is on manual adjustment and no auto level. And test your headphone on a other device to clear that your headphone is not broken. If all these options are correct you headphone pre amp of the XP 50 may be damaged or broken.

Transported Roland KR-177, toppled - pedal assy needs replacing


Good grief! FInd a tech that knows what he is doing. You can replace the plug and/or the jack. Each is a few dollars at most. You can even do it yourself. If you can see where wires went just buy new parts. They are probably available even at Radio Shack.

My roland xp-50 keyboard is dead.


Ok guys. Just got mine XP50 fixed with the "No Display" problem. The LCD screen was blank without text and only shown orange color. The problem is one of the capacitors on the main board was dead. I have replaced all 3 caps on the main board and the problem is solved and if you are a little handy on soldering, you can do it yourself. The 3 caps you should replace are:

- C901 (I used 16V 330MicroF)
- C65 (I used 5V 4.7 MicroF)
- C 902 (I used 16V 330 MicroF)
