I accidentally plugged my 110V amplifier to 220V outlet.It has no power anymore.what possible solution for this. Thank you very much. Do I need to replace the rectifier in it's circuit?

probably need both as the extra 100 volts would burn the board and the motor
it is never advisable to buy electric equipment from another country because of the voltage differences but even then the plugs are made different so that the cord will not plug directly into the power outlet.

I suggest contacting the manufacturer as there may be an internal "reconnect" that would allow 220v operation. Good luck!

Most likely you have damaged not only the power supply but also the D-Link wireless router unless the power adapter is a multi-voltage power adapter. Check the label on the power adapter and if the input voltage is a fixed 110 volt power supply you are in trouble.
You can try getting a 110v power adapter and connect it into the D-Link and if it works then you are lucky.

plugging a 110v device into a 220v outlet is not likely, as the plugs are a different configuration. In the event that you somehow managed to do that, your device is probably fried, as that would be to much voltage. Hate to say it; but you are probably gonna need a new one

You have damaged your machine. Place it into the bin and go buy new.... or maybe if you are lucky you can find someone who can fix it.

If the AC unit is 110V then you must plug it into a regular 110V outlet. You cannot plug it into the 220V outlet. Either get a bigger 220V unit or use a 12 gauge extension cord to get it to a 110V outlet.

With a bit of luck just the internal mains fuse failure. Otherwise could be transformer failure or a verity of other things.

If you are lucky you would have lost the fuse on the sub woofer module which powers the whole unit. If not, yes you will need a qualified technician to look into the matter because its not a small offense to plug a 110 device into 220v.

remove the rear cover and replace the fuse.

Hello,

There are two possible scenario's when you accidentally plug a 110V device in a 220V outlet:
1: The power supply to the device you plug in gets fried. this is your best case scenario. See if you can borrow a Wii power supply from a friend and test your console with this power supply. If this works, you just need a new power supply and all is well.
2. Your Wii gets fried. Worst case scenario: your Wii got fried. If it is still in warranty, see if they will cover this damage under the manufacturer warranty, if not, I am afraid you will either need to pay for repairs or buy a new console.

I hate to be the bearer of bad news, but plugging a 110V device in a 220V outlet generally will fry one thing or the other or even both.
