The power board bowled up because it was 110 voltage and they plugged it in a 220 voltage power and the system is not working again. I am very worried not knowing what to do with my system.hope you will help me get my machine back thanks,

if plug into 220 start saving for a new one you will burn it up

OK now so you plugged it into 220 when it is supposed to work with 110 and after you replace the fuse it still blows again this may be because of the high voltage the voltage could have caused the insulation on the wire in the transformer to burn off resulting in a short thus lowering its resistance and increasing current flow which will cause the fuse to blow over and over again no matter how many times you replace it . so my advice is to not plug it on again as it poses a risk of fire

110 volt to 220 power converter 220 volt to 110 voltage ...

110-220 volt voltage converter power transformer 220 volt voltage converters 240 ...run on 120 volt 60 cycles (60hz) and most of the worlds run on 220/240 volt ...

If you are attempting to connect your laptop between 110 and 220 volt power outlets, you may be able to do so already, take a look at your power cord's transformer (brick) and read the input voltage. If you only can use 110 volt AC Input Voltage should read 115VAC. If you can do both, then it should read 110-225VAC. 

If your power brick supports 220, then all you will likely need is a plug adaptor, found at many electronics store. If not, you wil need to stop in at a computer store or an import store and get an international transformer, which are set up to convert many different country plugs and many common voltages.

Good Luck!

Hi

check all semiconductor in the power board and look for a shorted and open parts! then replaced the defective parts.

Thanks!

Please check Input Voltage 110 ~ 240 volts AC at rear or bottm side of unit. If same is written there, its Auto Voltage Operatable and can be use on 220Volts.

It sounds like you hav blown a fuse. Hopefully just a fuse, connecting a 110 to a 240 will hurt.
Most equipment survives short term high voltage but sometimes it just can't take it.
if it's not the fuse then it's very likely damaged the power supply which will require the expert help of a technician..
good luck !
Ps the 321 is a very nice bit of kit..

Well, as a rule for electronics:
The United States and Canada use 110-volt electricity.
Most countries outside North America use 220-volt electricity.
Unless your appliance is dual voltage, you need to use a "converter" or a "transformer" to change the 220-volt electricity into 110-volt electricity in order to use a 110-volt appliance.
If your appliance is dual voltage, you can switch it to work on 220-volts, without a transformer or converter.

HOWEVER

Desktop units have a selector switch for 110 / 220 volts., which is done away with in the case of laptop one's which sense the input voltage and regulate accordingly.

I think your main concern is just that you have an adapter for the plug to go into the wall outlet.

Hope that helps :)
