No Sound from FR Channel

I get no sound from my front right channel of the amp.
I tried changing the ICs and the speaker wire but nothing work.
I connected the FR input from the preamp to other channel and it works.
All channels work except the FR.
I have opened a ticket log but if i can get some tips here on the forum that will allow me to fix the problem.
Is this a blown fuse problem or it's something more deeper.
I would really appreciate your responses.
Thanks

Call the support number. I've found Outlaw support to be very responsive.

Cheers,

I talked to the CS and they were extremely helpful.
The fuse might have blown out on the FR channel.
Thanks,
