# Is this something fixable?

A neighbor gave me his Samsung blu-ray home theater system (model #HT-BD1250) because there was smoke coming out of the back and he didnt want to fiddle with it. I opened it up and saw it had a burst something. I have included the picture.

After googling around I cant even find what it is. I think a capacitor but the pictures of those are cylindrical. If anyone could assist me and let me know if it is fixable, and if so how would i go about fixing it. Thank you.

Looks identical to the other 5 in the same position, what is the number on those?
Capacitor by the look of it.

0.47μF 160V to me..... but some other checks to establish the full extent of the damage (burned board?) and maybe WHY it blew up in such a spectacular fashion?

The components look to be part of the snubber circuit (across the speaker output).

The other identical ones say 474 j 400v

I have no experience with this. What would i look for as a cause? If it is burned is it unusable?

The 2nd photo shows that there is more damage, a overheated / burnt resistor, PCB, .....

My guess is that the capacitor failed short circuit.

Hopefully the damage is more cosmetic than it appears.

I would remove the failed capacitor, and possibly the one next to it and clean up the board as much as you can. Isopropyl alcohol on a q-tip would be my first method. If there's clearly residue under other components then you may have to remove them too, but let's hope that it was all smoke and no fire.

You may have to clean the good components before replacing them. But check for damage on the board first.

I am suspicious of the failed cap. The leads look too be formed exactly like the orange caps, but the colour appears too uniform to have changed due to heat or smoke. See if you can find any evidence of uneven colour or remaining orange bits.

A proper repair needs proper documentation.
model #HT-BD1250
I found the service manual for the model HT-BD1255 (same as yours)

So 470nf it is, I wonder how that buddy 'xploded like that.
