I read the topic you mentioned, but i have none of this problems.
The only problem with this CDi4000 is that channel B produces a
"thick/bang/pop" sound immidiatly when the amplifier is switched
on. For the rest the amplifier works fine (as far as i have been tested).
At this time my workbench (its my daily job to repair professional
audio equipment) has been "wasted" to repairing a Chinese OEM amplifier
with blown output devices. When this one is fixed, i going to try
to repair the amplifier, because i'm pretty sure its a hardware problem.
In the past i repaired four Crown XTi amplifiers (one with blown output
devices, one was needed to replace the LC2412 DSP, one with a BIAS problem
and one with a blown power supply) so i'm little familiar with the XTi
I just recieved the service manual from Kip (thank you very very much!)
for the CDi4000 and at first sight i looks very close to an XTi, so
i hope i'm been able to repair it.
Do you have any idea where to look for? I still have the idea that it
could be a BIAS problem. At the same time the "Ready" LEDs are lit,
the power amplifiers itself are been activated because the BIAS starts
at the same time. Normally until this time the amplifier cannot produce
any sound because there is simply no BIAS to turn on the output devices.
So i think it could be a BIAS problem.
Just my toughts. Do you have any other toughts about this?
