Re: plugged in 220v by mistake

Did you check trafo? Do you get any power on secondary coil?

Iplugged my jvc rx-7010vbk 120v reciever into a 220v outlet, does it have a power supply fuse that would burn out or is the whole power supply shot, what parts do i need to fix it

more than likely the whole board is shot
fuses only control current flow and break when that is exceeded
It is the voltage that does the damage that same as when you put 12 volts through a 6 volt bulb

Voltage change 220v 240v

These number have no bearing with amp issue. It only means if you're in North America or International with 220 volts. However, your problem is power transistors
that are shorted which is the cause of fuse blowout.

If I would buy a Onkyo TX-NR616 in the US (110V) and take it Europe (220V), wouldn't it be a solution to simply exchange the power transformer for a 220v one?

An stepdown transformer is needed should you buy in US and use it Europe

However, if your on a technical side , trace the primary windings , and check

There are European versions which are already 220V, no need to convert.

It was 110v and plug in 220v -no power

There are several parts that are going to be check like the ff:
1. Glass fuse - Some unit replacing the fuse alone fix the problem.
2. Stepdown transformer - if it has then check for open/shorted winding.
3. Regulator I.C.
4. Fusible resistor.

All parts are on the power supply section.

1 & 2 can be DIY but 3 & 4 are needed to do by the techinician.
If you replaced the fuse and blew again then you have a shorted parts. However if it has no reaction then you might have an open parts.

Pls rate my help..

Thanks for using fixya.

If i accidentally plugged it to 220 volts and it was burned in a seconds can it be repaired?

Good day sir/maam, Yes it can be repaired. if you have plugged in a 110v device to a 220v ac mains, chances are its toast, your onkyo's power transformer is burnt, the repair is replacing the toast power amplifier, or we usually rewind the power transformer specification, after the replacement, you may need to check the power supply section for shorted power regulators, and rectifiers. If you choose to send it for repairs, the service is usually reasonable.

Hi, I'd like to use my Denon at overseas where

There should be a switch that you could set to the various voltages. Normally a round switch in one of the corners on the rear panel that you can turn with a flat screwdriver

Plugging in with multiple voltage requirements.

no... it will put out 220volts, same as the wll socket voltage. you will need a 220v to 110v stepdown transformer to run the sub.

Yamaha reciever will not power on

If the receiver is completely dead, the problem could be as simple as a blown fuse. If there is no visible fuse holder on the back panel, you'll need to remove the cover. There should be a circuit board near the rear of the chassis where the line cord attaches. You should see a small glass fuse held by clips on the circuit board. Visually inspect it for a break in the small wire inside. Alternately, check it with an ohm meter. If the fuse is blown, replace it with the same amperage fuse rated for 250 volts. (The amperage is engraved on one of the metal ends i.e 0.5A). Before replacing the fuse, do a visual inspection of the other components on the circuit board looking for any signs of burning or overheating The over voltage may have damaged other components, in which case you'll need to take it in for service or scrap it. Most Yamahas have a separate standby supply. If yours has this, chances are pretty good the damage is limited to this area. If the main supply is damaged, it may not be worth fixing.

Receiver won't power on

My receiver was turned on and plugged into a surge protector along with my LCD TV. The power went out and everything shut down.

Plugged into 220V outlet by mistake! Help!

I don't know for sure, but I suspect that if you open it up, there should be a fuse near the power supply portion of the unit. It may have taken the hit for you and can perhaps be replaced easily. (As a disclaimer... be sure the unit is not plugged in when you open the case! And only replace the fuse with another of equal rating.) If it's not a fuse, then you probably smoked the primary winding of the transformer. If it got past that, you may have popped the rectifier and/or capacitor(s) in the power supply.
