In Topic: Loud 'bang' heardible from channel A when turning on XTi4000

11 July 2014 - 11:40 AM

I've heard bangs before, and usually a fault had occured! You seem to imply that the bangs are heard but the unit runs fine!! Confirm.
Have you applied any recent firmware updates?
Is the main board still inside the amp or have you removed the board from the chassis?
Bang : Do you hear this through the speakers or 'mechanically', audibly coming from the amp?

There seems to be two versions of the main board : the original version has the output heatsinks resting on pads like skids. The heatsinks are held down via screws to the chassis. If the main board is taken out of the chassis, you wouldn't have enough pressure to keep the heatsink's pressure on the power pads (under the heatsink).
The newer version of the main board has some pins protruding from the heatsinks making a proper contact with the power rails.
If you were to test the amp with just the main board, I wouldn't power the amp to speakers outside the chassis; Just make sure the amp is operating normally and install it back into the chassis before power tests.
Verify the filter caps (both hi and lo voltages) for domed tops! Make sure it is the cap that is domed and not the plastic top!
I hope this helps.

Hello Stanley,
I would highly recommend that you replace the display module; It is very difficult to repair the backlit panel, you would need to find the appropriate white leds.
Also, this version of [your] the display board may still be problematic : intermittent connection at cable end. All in all, replace the display module. :)

I received an answer from Crown : Basically it means the product's designation :
SML : XLS1000; MED : XLS1500; etc.
There are two more designations : Large : XLS2000 and Extra Large : XLS2500

Hope this helps!

What's the context, Stanley?

I think that we should start by having specific topics on the different amps, to have the users 'share' their interesting troubleshooting tips and solutions.
