The Roland Pad 80 has a contrast control, if it's not correctly adjusted, it could cause it to appear all black or all blank.

If the LCD were bad, it's uncommon for both sections to both go out around the same time, since it uses two seperate 7 segment LCD components. About the only way to cause both to go out at about the same time, would be to get the equipment wet, or let it get way too hot or left sitting out in the sun, long enough to dry up the "liquid" part of "Liquid chrystal display".

    Also, there is a way to try resetting everything to factory defaults which may or may not help, depending on if it might also re-center the contrast control, but at the expense of losing any saved programs or data. If you'd like to try resetting, the procedure is:

Roland r8 has flashing green light


Are you using the correct AC adapter? An aftermarket unit will do this if the power is insufficient, or the polarity is wrong (- / +). If you're using an aftermarket unit, it may not be providing the right amount of Amps and Voltage to the unit; causing the display to blink. You can try this cord to help: http://www.powerpayless.com/ac-power-adapter-for-roland-r-8-r8-drum-machine.html

Roland cube street water damage repair


What part of it got wet will determine the course of action.

If the whole unit were submerged, the unit may prove more time consuming to try to fix than to locate a used one. However, I have salvaged imersed laptops before. the procedure is not much different- make sure the unit is as dry as you can possibly make by blowing a fan on it for an extended period of time.- Days.

Once dried, use some contact cleaner on the jack contacts and interupts, any manual control and any switch.

You can then apply power. If nothing lights up, check and replace fuses as needed. Also check the power supply board for failed caps or rectifiers.

Once the power supply is known to be functional, systematically check the LCD display and the aspects of the amp that it controls. This board will be the most vulnerable and most likely to be the source of most issues you will encountr.

If the display survived intact, and amp does nto work, apply a signal to the inputs and trace the signal through the amp with a set of headphones set up with test prods. The problem will be where the signal stops.

Screen on roland td7 lights up but is blank


Look for a contrast control for the display... often a small tweek shaft that comes out of the case. This is only if the thing operates but has no display.

I NEED TO KNOW HOW TO SET UP MY ROLAND JUNO D WITH MY AKAI MPC 1000, PARTICULARLY HOW TO SET UP THE MIDI ON THE ROLAND.


Simple way is MIDI out from Juno to MIDI in on MPC, then (depending on how you want to work), connect MIDI out from MPC to the in on the Juno. If you do this you MUST turn local control off on the Juno or else you'll get double triggers (internal + msg in from MPC). Now to record sequences on MPC , set MIDI to as track in setup window (on the 2500, this is accessed by pressing MODE then pad 9, then press button under the corresponding tab [on LCD]) then set your MIDI channel by port, meaning if your MIDI cable is physically connected to out A, in your LCD in bottom right corner it will show as follows: 1A. This indicates you are transmitting on MIDI channel 1; port A. Remember, MIDI IS NOT AUDIO!!!!! Since the Juno is a synth and not a workstation, all transport controls are handled by the MPC, that's pretty much it... Hope this helps a little, enjoy!

P.S. Go to mpc-forum.com its THE sh**! They also have links for their e-book I have one for the 2500 and its awesome!!!

The sustain pedal is permanently on!


You MAY be trying to use a Roland pedal on an instrument that requires a different one.

The Roland have a normally closed contact where MOST others are normally open.

If you are using Roland equipment, then use of another brand OR a broken cable will cause this as will a shorted cable with other brands.

It looks like you MIGHT have a Technics given that number you posted. Not sure of which polarity pedal you require with that, So you need to test it.

Plug in a regular instrument cable and see if it sustains with nothing at other end. If it does, you need a normally closed one.

Micro BR power Adapter


You may have damaged the data on the memory card. If you have no display at all carefully read page 125 of your manual.If it doesn't display with the adapter plugged in try new batteries. If it still doesn't display anything, contact the dealer you bought it from or try contacting Roland. This site should help:http://www.rolandus.com/support/service_centers/
