problem with luxman l530

[sub_arctor]

Hello
i just bought a luxman l510
there was almost no sound on one channel

i opened it, i try to connect the speaker cable directly on the board (i know it's stupid) and i think i make some sort of short circuit

i saw some smoke, and now, the "temporization" button (a little orange led near the power switch) light on but doesn't stop clicking
before it was clicking a little bit then stop and i could hear music

Someone would know what it could be and what do this led indicates

I check the board channel (but i didn't remove it) but i didn't see any part burnt ...

Thank you in advance for your advise

Julien
