Mb quart raa1000 powers up no sound

[Groundcontrol]

I have a mb quart raa1000 my brother gave to me.
It powers up fine and is getting signal (clipping indicator flashes with music)but produces no sound.
Nothing is burnt inside the amplifier.
What possibly could it be?
He said it played when last he used it.

Photos? No one has experience with every amp. This one may be similar to something more common. Post photos of YOUR amp.

For some reason I can't post photos.
It says can't execute operation due to low memory.
The MB quart amp is a Rockford fosgate made MB Quart raa1000 class d monoblock amplifier.
Manufactured in 2004
The amp is black and It has power and speaker connections plugs to jack into the amplifier in both ends
The controls for the amp are mounted at the top of the amplifier also.

Are you using the 'go advanced' and 'manage attachments'?

I just posted an image (and deleted it) with no problems.

I didn't think I needed to specify but the photos were to be of the component side of the board.

Are you sure that it's powering up? It appears that both power supplies are blown.

Side note, this is a design similar to that used by lanzar and lightning audio (rockford). not the circuit used in their BD amps.

What's the rail voltage and the voltage on the power supply pins of the various op-amps?
