No Out , CR Nearfield

[salvaes]

Hey guys how it goes? I wanted to ask a question.
After reviewing the forum completely, and read countless times a problem.
No sound, which most times it is said that the apogee clock card check.
Well my problem is this.
yesterday after more than 7hrs working without any problem, I started to make a creaking by CRMain out, and from that time stops for no sound out any of the following CRMain, CRNearfield, Master out.
table apparently works well, when the problem had nothing connected to ADAT solamante was working with the previous table.
the input level meters mark but the master does not dial out.

By the time I made the following tests.
all cards out. mfx clock in & out ufx
clean contacts.
disconnected from the CPU
and the whole operation in reverse with the following result
I have no sound output.
vumeters mark the entry level, but I can not hear nor headphones

Thanks Peter
The link to the database and look at it earlier, before it happened this fault table was already giving Vpots random errors, and the resulting cracks in the audio output, lost watch, I proceeded to the replacement of Rail Capacitor
once replace all seemed to go normal was 7 hours working until I stop sound, then look at the service manual, I saw what the status led, both the board dsp, and the brainboard, and in my brainboard have lit green and red, also stopped working yesterday the VFD and revised several times all the wiring and the result is the same, the table everything works perfcectamente except as discussed

Hello friends, I have the problem resolved.
The problem was, in the EPROM of brainboard peak voltage I corrupted half the startup program the EPROM, once got the file with an engraver of eproms and I managed to create a new eprom, which once installed on the brainboard everything works perfectly.
