Smoking from my amp?

Hi,
I have a six channel amp that worked fine until I put it in the box five months ago for building a new room. Last night, I connected all my speakers to it and the left channel didn't work.
After turned on and off a few times to check for which one was damaged (speaker, cable or amp), I saw smoke coming out from the amp and smell something burn.
I opened the cover and see two fuses were blown, but didn't see any burned parts. I plan to replace the fuses and hook it up again. However, my friend told me that's not a good ideas because smoking and smelling burn that mean some parts already burned. He recommend me sending the amp to manufacture for repair because the damaged is more than the blowing fuses. Acording to him, blowing fuses doesn't create smoke, and hook it up again create more damaged.
So, should I replace the fuses and turn the amp on again before seding it for repair? Please advice me
Thank you very much.

Tubeking, I also supect the shorts of speaker wire because my amp and speakers were fine in the old room for almost two years. I run a speaker wire inside wall in new room, and there were a lot of things happened during the construction.
How can I check for shorts in the speaker cable to see if it was really damaged?
Thanks!

You will need a volt ohm meter. set to ohms and test the speaker wires with nothing atached at the far end, this will tell you if you have a short, the meter should read 0 ohms. Then if that is okay short the far end and you should see something in the .1 to 1.5 ohms on the meter.

Good Luck

They put smoke in at the factory, you are not supposed to let it out! You must send it back to reinstall it.
