Volume not responsive to knob


If there is any sound from speakers, but don't change volume by knob, and after power switching off and on don"t solve the problem (if there is a batery power in keyboard, take out these!) - there is a hardware (electronic) problem; repairable only in serviss.

I own a Behringer Ultratone K3000fx 300 watt PA/Keyboard Amp that stopped putting sound out. The amp is getting power just not putting out any sound at all. Just wondering if this is an easy fix or I...


This is most LIKELY an electronic problem... possibly in the final power amp. Repair may be a simple failed component or a mass number that fail like a stack of dominos. Take it to a shop for repair.

Hi The first 11 keys of our keyboard have not woked since new. If my girls press the play/pause button then it works. Is this a fault of the keyboard or are we doing something wrong? Thanku


Check the switch to be sure the keyboard is in normal mode and not chord mode. This will cause there to be no sound unless you play a chord on those first 11 keys. Pressing play activates whatever song is loaded at the time, allowing full keyboard use.

I have an older Casio, and the same thing happens all the time, especially when I'm in a hurry and don't check where I put the switch.


Hope that helps!

Types wrong letters


It sounds like you have the 10,12,15,PS selector switch on PS with a 10, or 12 print wheel installed. Return to the left margin, move the switch to 10 and type.

If the letters and numbers don't work, what is left ?

Keyboards are electronically organized into a matrix of rows
and columns. An internal processor monitors the columns
as it activates the rows one at a time in rapid succession,
or vice versa.

If a complete column or row is bad (electronically) then
a subset of keys will not work. For a PC, the detected key
strokes are encoded into special binary codes called
"scan-codes", which are sent to the PC over a serial cable
or a wireless link.

The operating system then employs several layers of
translation to determine which keys you pressed,
based on the language and location, as well as the actual
application actively running at the time. Also the keyboard
itself is programmable and re-configurable by software running
on the PC, such that the letter "A" for example, can generate
different scan-codes, depending on the selected keyboard
layout.

On laptops, multiple functions and the numeric number-pad
are overlaid over the main alphabetical section, such that a
single key can serve many functions, depending on the current
operating mode.

1) Make sure you don't have a software problem, and that your
keyboard is not stuck in some bizarre or foreign operating
mode.

2) Make sure that the wireless keyboard's batteries are not weak
or dead.

3) Make sure that there is a clear communication path between
the physical keyboard and the USB transceiver plugged into
the computer. CRT monitors and large metal objects will
interfere with this signal.

4) Reset the keyboard: Unplug the USB cable, and plug it
back in, or re-boot the PC.

5) If these easy checks don't fix it, contact the manufacturer,
or replace the keyboard, as these things are generally not
electronically serviceable

Typically the processor/controller is a single proprietary chip,
the circuit board has multiple layers which are very hard to
trace or repair, schematics are non-existent, and the switch
mechanics are very finicky and delicate. The actual
key-switches can use dozens of different principles, including:
capacitance, inductance, carbon pressure pads, conductive
foam, printed pressure bubbles, reed switches, optics....
you name it.

There is no practical way to repair these things, and at an
average price of $25-$100 for a new keyboard, it
is hardly worth it.

There are a number of issues that could cause this, the most likely culprit is the power supply, when I say power supply I mean the internal power supply, 
This means that you have already obtained a good "known to work" AC to DC power supply, and tested it on your keyboard to see if that is the problem. 
If you have completed this step, then your next step is to test your unit with batteries only, if the keyboard works, then you know your problem, is internal to the keyboard. 
There are two issues to check, before proceeding please read the following note.
 (a note here for those who have no experience working with internal electronics)
If you have no experience working with internal electronics I would not recommend, opening your keyboard. 
Two reasons, one, will void warranty if it still is under warranty. 
secondly, you could accidently cause more damage to the unit. 
Now if you are still reading, and feeling confident, you know that as a child you have dissembled many many electronic devices, just to see how they work. 
If you do decide to open the box, disconnect the power supply to the unit including any batteries. 
open the box and locate the power on button, clean using a Dielectric cleaning agent, can be obtained at most electronic specialty stores. 
clean the power button, may work but doubtful, usually the switch itself is usually bad, there is a way to test the switch, however, that is beyond the scope of this answer, if you are following this you will most likely have the knowledge to do this. 
The second and more challenging issue will be the internal power supply to the keyboard, or the interface that connects to your ac to dc converter. 
This can be much more trickier, and I wont go into it here. 
If you test your power switch determine that it is good then you should consider getting the unit serviced by a technician. 
If you examine the boards, (electronic circuit boards,) and notice burned, connections, (darker than other circuits) then most likely it will not be worth trying to fix. 
Hope this helps somewhat, if nothing else, take this print out to your local service dealer, and that will help in getting your keyboard repaired, 
Delete this part, before taking this to your dealer, 
Most electronic products can be easily fixed with a power switch, or power supply, however, many dealers will not tell you this and give you an estimate of fixing the unit that far exceeds the actual cost of repair, 
an example, in a local TV repair shop, a friend brought in a wide screen Plasma HD TV, quoted repair, $654.00  problem, 
power supply, actual cost, $75.00 my friend ordered the part online and with the help of a friend installed the new power supply returning his unit to full functionality. 
So beware,
