Because Of My Careless?

Hi, I was carelessly plug the power cord of my KENWOOD(110V) into 220V supply. After a few seconds, I find out I forgot to plug KENWOOD's cord to 110 transformer. But it was late, my KENWOOD doesn't work anymore. How do I fix it. Which part of KENWOOD are destroyed? Any advice.

 

Your Kenwood what? Radio?

Maybe, if you are lucky only a fuse is blown. Did you see smoke or smell anything. Do you see anything melted?

More information will get better answers.

 

No, It is Cassatt that can play CD, tape and MD. No I didn't get any smell. And I haven't open it up? Any advice. Thanks

 

If you are hoping to fix it yourself, you will need to open it up...

Give a model number and pictures of the insides...

 

Model No is RXD-SE5MD(S)

If your power supply is like the one shown here, I would look at your caps, diodes, and, possibly, the regulators... and verify the power amp output...

EDIT: Looks like mbohuntr beat me to it!

 

Checking, for a minute

 

It look like the same. And What I found out is the fuse is turning black. Is it the symbol of blow out? Any advice?

 

A fuse that changed color is usually bad, and you're really lucky if that's all that went wrong!

 

Very unlikely the fuse is the only thing gone. Blowing the fuse meant high current flowed through it and that current had to go somewhere.

The diagram doesn't even show in input line fuse.

 

It will have blown the primary of the mains transformer, which then took out the fuse. So a new power transformer will be needed.

There may be something blown after the secondary of the power transformer, but not always.

 

You're going to need the aid of a digital multimeter. If you don't have one, then get one. Without it you're searching in the dark.

Even with a multimeter, without knowing what the part was or a schematic or service manual plus some electronics skills the OP is probably better off going to a repair shop.
