20 Most Recent Crown XS1200 Amplifier Questions & Answers

If you are not seeing any indicators, you may have a fuse open, power transformer, bridge diode, etc, etc. When you first plug it in, do you hear any clicks coming from the unit itself? If you need more information, or would like to inquire about having your Crown repaired, please visit my website at audioserviceclinic.com. BTW, I worked for Harman Kardon. Crown is one of their products.

You may have two speaker wires touching eachother (shorted) or one of your speakers may have a fault and not giving enough resistance to the amp (shorted). Last option is that one power output transistor is damaged and appears to be a short circuit to the circuit protection system.

Hello,

A common problem for these is bad capacitors in the power supply, Remove the back from your Amplifier and look at the power supply on the middle section of the amplifier

You will see bid round capacitor that are bulged / domed shaped on top usually these are valued any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same capacitor rating but a higher voltage.
Hope this help in solving the problem....

I would study the service manual and service notes to find out why the temperature sensors do not work. Probably a supply rail down I would think to affect both of them.

The Power Crown XTi 6000 is a power amplifier, and it sounds like it is activating its protection circuit and not generating a Pulse Width Modulation (PWM) signal. There could be a few different reasons for this behavior. Some possible causes include:

• Overheating: The amplifier could be overheating, causing the protection circuit to activate in order to prevent damage.
• Short circuit: There could be a short circuit in the amplifier, causing the protection circuit to activate.
• Input signal issue: The input signal to the amplifier could be causing the protection circuit to activate. This could be due to a problem with the source, such as a malfunctioning mixer or a disconnected cable.
• Output impedance or load mismatch: The amplifier may have a mismatch in output impedance or the load impedance which can cause the protection circuit to activate.
• Firmware or software issue : There could be a problem with the firmware or software that controls the amplifier, causing the protection circuit to activate.

Without more information, it's difficult to say for certain what the problem is. It's recommended to check the manual for troubleshooting steps and also check for any possible firmware updates. If problem persist it's recommended to take professional help.

Not most service manuals can be downloaded unless you use a model close to the original. Try service manuals.com

Google should have a manual for your 1000 amp thermal and also try on the companies official website too for a manual. Try searching on YouTube as well and YouTube should have videos about amp thermal on - Crown Audio Players & Recorders

Probable power transistor failure.

If you have eliminated any shorted speakers, cables etc, then the only other cause is a shorted device on the power output board. Probably a device on the heatsink.

Hello, Sylvia - I have no idea what entity you meant to receive your question. You posted in the Fixya.com website, which is intended for asking and answering questions on how to go about REPAIRING THINGS. Plus, your question landed in the Fixya category for Crown (brand) Audio Players & Recorders. Perhaps you meant to message Netflix, or your local public library, or a person from whom you borrowed the DVD, or someone to whom you sold the DVD, or . . . Best wishes.

Is the fan supposed to be on. On some units it runs all the time on others when the temp hits a certail level. Which is it for your baby?

It's best to assume there is a short circuit in the power amp board. The unit is going in to protect mode to stop it blowing fuses etc. Could be caused by bad speaker wiring or connections by the way.
