20 Most Recent Roland CUBE Street Amp Combo Questions & Answers

Most likely the acid ate the internal power supply, but if you can dis-assemble it and clean any trace of gunk with a toothbrush and electronic cleaner, including the fuse and it's contacts, maybe you'll get lucky.

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.

Hi, Quick Check. Very often the input socket which is soldered directly to the circuit board, will have a broken solder joint. This is common on a very large amount of equipment. Try waggling the plug about and seeing if the noise comes and goes. Easy fix, re-solder joint. Permanent fix, connect socket to board with flying leads, or fix socket to board with hot glue or epoxy resin. All the best, Chris the Fader.

Hello. Hello. Generally the upper LCD display of bars is an indication that the internal battery is on it's way out and needs to be replaced.

Yes, you can use the second pedal on a Roland BK-5 keyboard to transpose the key of the music that you are playing up or down by a semitone at a time. To do this, you will need to press and hold the second pedal while playing the keyboard. You can also use the transpose function in the settings menu of the BK-5 to adjust the key of the music that you are playing by a specific number of semitones.

I am also using IOS and Android. So how can I improve some features? The black screen helps you relax when using the computer too much.

It's a Chinese made Roland and no service information is available as when a fault is found the main board is replaced, eliminating the need for service information. I would check that it is a stereo out jack and not mono. If it is a stereo out, check that both input phonos work. If they do, replace the faulty socket or damaged pcboard.

Sounds like a blown motherboard to me. It needs to go to the shop.

Hell,

there is no display on your Roland Handsonic because the screen inverter or screen board panel is faulty. This has to be replaced for you to see your digital display again.

So its either you use it like that without the display or you take it to a repairer for fixing.

Take care.

This depends entirely on what you personally define as 'Good'. The only real answer to this is try it, listen to it and decide for yourself.
