Crown XTi 6000 2Channel Amplifier - Answered Questions & Fixed issues

Hello Anonymous, Here are 2 links to Harman ( Crown ) Support and Service Manual. Crown suggests you call their tech support First to determine the need for repair. Best of Luck, JP https://3e7777c294b9bcaa5486-bc95634e606bab3d0a267a5a7901c44d.ssl.cf2.rackcdn.com/product_documents/documents/2862_1433871166/XTi_Series_Service_Manual_original.pdf https://www.crownaudio.com/en/support

Cannot give you the diagram but repaired some of them. whats the problem?

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Thank you for using Fixya

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.

Component over heating . Main input output ic defective.

Do you mean that you would like to change from a 3 wire cannon plug to a 1/4" female?

Replace/repair fan.

That is a subjective statement. You need to measure the SPL at the speaker and check against the specs and also measure the power from the amp to have the data to check and compare with. That will give you an objective answer. You could have lost part of your hearing, I do not know!

I would suggest you take it to your local Crown repair depot. It sounds like a fault in the internal protection circuits or the outputs are blown. Without a lot more information I cannot help.

Unfortunately, there may be a number of reasons. it would be much easier to diagnose if were taken to a n authorized repair center. Here is the link to Crown support- Service Centers

Check speaker to power bank protection circuit. The circuit is faulty indicating to the power amp that speakers are disconnected that shuts down the amp to protect the unit
