Sadly, your problem indicates a circuit problem inside the amp. Either the protection circuit or the output stage is messed up. If you don't know how to get inside, best to get some professional help. Sorry there isn't better news on this one.

Issue With Pre initial Rom Fail To Voltage Routine Check Cause... Static on The Chip Unit Posibility Security Relais Wont click On.. Do do so check for Fuse or red push botton over load security Braker at the back of your unit.. if your fuse is good Well Open the case and surch for more fuse inside of the unit Make shure the unit is unplug from the wall...Then check The voltage on the Transformer to make shure you have the right voltage then check The Regulator The Coil and Capacitor If your not shure Well send it to a Reapair Shop it your best choice Amp cant be dangerous for hazard shock....Good Luck

Try these for starters!
Is the power switch broke? Check the power cord! Are any internal fuses blown. Look inside for damage/burnt parts. Are the printed boards broken? after say being dropped? Is the transformer working? Check around the power supply area for faults.
Note - be careful your dealing with mains electric!

I think Radio Shack has a kit for this problem. Not sure about the cost, it's been awhile since I dealt with this problem. Good Luck.

Haven't found one yet tho i'm wondering... what issue/problem are you having with the amp ?

Robert

make cleaning to your filter by air blower------- keep good ventilation around in the pass of air(in-out)----after you finish try to test your amp by connecting one speaker only at a time until you find the bad one--------------if all above did not pass you will have internal problem of hardware and needs service center.

take off all your speakers cables from amp and test if it is fixed you will have a problem in your cables or speakers itself-if not you have a problem in amp itself and needs to repair in service center.

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.
