My son accidentally plug a 110v bose 3-2-1 to a 220v outlet. What do you think is the damage? Do we still need to send it to a service center?

You should take your TV to some good electronic service and they should check if it can be repaired. Obvously you overcharged it and PROBABLY some part of the circuit board burned out. Maybe it's just a cable, or the insulation or maybe it has a massive damage. it's a question of verifying if damaged part can be replaced or repaired and for how much.
No way to tell for sure extente of damage, I'm just guessing.

Yes, the fuse is inside the unit where the power cord plugs in. Not accessible from outside the unit.

There is a safety feature that may have disabled it, contact your local service center. See page 115 in the manual. The manual can be gotten at: http://www.yamaha-hifi.ro/uploads/digital_uploads/Owner_manual_RX-V775_V675.pdf

There is a good chance the device is damaged beyond repair and it may require replacement.

exact location in Davao city for a service center of bose speaker need to be repair

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

Hi,
If that unit came from the states, the power would be 110V and in China tjhe voltage they use is 220V.
That means, you have to check the fuse in the radio, replace if it is already open.If the fuse is still okay, the power circuit has a burned parts.
My advise is to send it to a electronic tech or the nearby service center.
Hope that helps!

Hello nik286, hi, check first the label at the back of the TV, look for a voltage input something like a 90V-240V, if you see this, its an autovolt system, this type of power supply input is standard nowadays. Assuming your asking what would be damage, this could be anything from the fuse, thermal resistor, rectifier diodes, and the regulator IC of the power supply board.

Yes. The companion 3 system can be repaired for $75. Call Bose at 800-367-4008. They will also give you a new 1 year warranty.
