Crown Audio Players & Recorders - Recent Questions, Troubleshooting & Support

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.

It will be the boost cap near the power switch. 220if 35v. In fact 3 caps die which kill XTi and CDi series. Amps. 2 x 220ugf and one 470 uf. All. Located yon the freuont right edge of the main PCB. An actual crown tech

- Use your favourite search engine (Webcrawler is dandy) and type your question/info into it. - SEARCH ENGINES ARE YOUR FRIEND!!! Type in keywords and check the results. - I'm not an expert but it almost sounds like maybe a speaker relay or whatever on the amp has bailed out. Good Luck :) R

It could be a defective switching element but more likely something has failed in the right channel amplifier chain such as a a component or amplifier stage.

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.

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.

The most common problem found on FixYa for Audio Video Receiver's and amplifier's is:

My receiver/amplifier say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

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.

Possibley bad windings on the transformer. Not enough or bad insulation.
