20 Most Recent Crown CE2000 2-Channel Amplifier Questions & Answers

The problem depends on what you are putting into it. If you can make this an objective question somebody could probably help.

The power amplifier section should be troubleshoot for shorted output IC or transistor. If you wish to get some details; visit the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

The problem is not a fuse. The red light indicates that the unit is in "protect" mode. This means that a problem was detected in the final amplification stage and the unit is prevented from turrning on completely to prevent damaging either the speakers or the amp further. These are not the easiest to repair without prior experience and I would not suggest you attemt the repair. Please seek an authorized Crown repair center for assistance.

The problem sounds like a dead short issue and the amp is in protection. Check cabling to make sure there are no crossed wires. You can also check by swapping channel 1 and 2 inputs and outs to see if the amplifier passes signal on the bad channel.Also could be an amplifier channel failure if it does not. Have serviced by an autorized service center.

The Crown CE series of amplifiers have a 7 stage fan that runs as needed when the amplifier is working. Generally the fan is running at some point most all of the time, and you should be able to hear it ramp up as you push the amp to deliver more power. If the amplifier fan is not functioning, you may be in a thermal shut off mode that protect the amp from overheating by shutting off any signal. My advise would be to contact the manufacturer, and have it serviced.

Clearly a main power amp failure. Look to the device(s) located on the big heat sink and replace them.

Check fuses first

Have a look inside and see what the power amp consists of. You will find it located on a big heat sink. If you see a big IC with lots of legs it could be that has failed. Also look around for fuses.

Check your filter caps and your drive transistor On that channel that will also fix fan problem unless fan has problem of its own

It could be something as simple as a bad earth... Thats the common fault when this light shows try reconecting.

are you using 8 ohm speakers with an 8 ohm amp??? if ohms conflict , then it can cause problems

Hi,You can download the complete service manual including the schematic diagram also.Here is the link.Unfortunately there are many possibilities of faults and so I can not give you any solution. You should have given description about the problem.When you get to the site using the link it is possible that you have to wait a little bit to be able to download.After waiting you should see a button as "Get Manual" and simply click on it and save the file.Thanks.gylacz
