Crown I-T6000 Rare Failure

[opacheco]

Hi,

I am in the repair process of one Crown I-T600 power amplifier but it have a very rare and strange problem. This amplifier sound for 1 second(literally!) and after that it mute itself after the turn it on. I have added a short video showing this issue and I will be very grateful if someone can help me in order to find what the problem is.

Thanks for anticipated help!

I have written few minutes ago again, but the truth, I don't expect them to answer my request, anyway I sent a “Contact us” message.

By the way; I have any a little portion of its schematics and I ask to myself if Do anyone have a complete schematic copy for this I-T6000 Crown amplifier?

Thanks

The schematics are at the bottom of the download.

I just did a quick search over at a professional sound reinforcement forum (PSW). 

Nothing obvious recently about IT6000 issues.
