Roland Music - Page 3 - Recent Questions, Troubleshooting & Support


Hello,

if it does not power up, then it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter in order to test the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Take care........

The wires were probably broken or disconnected during the move.

Possible IC chip shorted or failure on the fader board.

Static is usually the result of a bad connection. I suspect there is a bad solder joint. If you are electronically inclined, use a listening device or oscilloscope and connect it to the volume control terminals if it is not present on the input to the volume control then it is the volume control that is bad which happens in old equipment best solution is replacing the volume control or you can try cleaning it with an aerosol product for this purpose.

If it hums when running on battery power, either your cable from your instrument needs repair, or it's the wrong type (unshielded or TRS) or your instrument has a problem, or you're in an area that has too much RF or electromagnetic interference.

All rechargeable batteries have a lifespan and they may be nearing their end. It may also be that t your charger isn't putting out what it used to. Best to take it in for repair so they can determine the cause of the problem.

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.

lucky you that wants to get burnt
disabling a safety feature is NOT the way to go but fixing the fault that wants you to do so is the way to go
