Hi, i just got Loudbox100 from US,do i need a power converter or it is fine to use it just with the adaptor?I am from Europe.

use a inverter 110 /240 volts in the power supply line
the problem is the different cycles

try plugging in without the bateries...Also check your adaptor as well as your ac requirements on your keyboard..It specifically calls for a Casio AD-5 Adaptor.

• 9V power supply; 850mA
• Positive sleeve/negative tip This needs to match your adaptor Good Luck

Bad power Jack...................

Hi, Assuming you have tested with another adaptor then invariably it is a broken solder joint on the power input connector.
Re soldering will work but eventually the same thing occurs.
Set the connector in epoxy resin (Araldite) or better still mount a new connector in the case and wire with flying leads.
All the best, Chris the Fader.

Either your key scanning section or the power amplifier has fried.
Try playing the demo song, if the sound can be heard then the scanning section is faulty. You may download the servicemanual from Elektrotanya com and repair the keyboard.

If you are using the correct adaptor then the most likely reason is that the socket where the adaptor plugs in has broken away from the circuit board and will need to replaced/resoldered.




if you need a socket Google : Yamaha PSR power socket ( KPA3 / PA130UK / EPA3 ) (LB30226R)


OR if you have used the wrong mains adaptor and the polarity was reversed you may have damaged the diodes / voltage regulator on the power input.

not unless its set up for 220volts also, some of the older models have a switch you can flip to make that change, the newer ones don't, most everything in Europe is 22volts,, they do have adapters with voltage step in them, so shop around, they can be pretty cheap depending on the wattage required.. hers a few you can check out

hi,
You have to check the working voltage of the adapter of you device. If it purchased from US then it will be 110V. I think the Line voltage in Australia is 220V.Also You have to check is there is any input voltage selector in the in its adaptor . If it there you have to change it to 220V. If there is no such selector then you have to buy a 220v to 110v converter .Then connect the out put of that converter to to your device. You can by this converter at any electronic spare part shope near to you. Or you have to by a new 9V 1.3Amps AC adaptor. When you going to by the converter or a new adaptor take the device. If so they will explain you how to connect the converter or adaptor . By changing a fuse you can't change the operating voltage. If The adapter is designed to use in 110V then the fuse will blow. If you change the fuse and make more experiment with it it will make the full system useless.
ok

im pretty sure they sell a converter kit for pretty much anything, so i wouldnt see why not

You can get that fixed if you can find someone who can solder. The jacks wear out over time on a lot of things. The jacks themselves are worth about $1 but it is the labour to open the case and solder a new one in.

The contacts in the jacks are spring loaded so these can wear or get damaged etc. So eventually they won;t make good contact and you get your problem. You see this a lot on laptops. You can twist or apply pressure on the plug until you get it to power up. This is more luck than anything when it works and eventually it will get to a point where it won;t connect anymore. This really is a simple repair but finding someone to solder the new jack in is the problem.
