I believed you got 1 or 2 electrolytic capacitors were dry out so it missed 17V + or -- regulators in the preamp sections that why both side light are on If you go to 1 of the service center Crown in your town it would cost you between $100 to $200 I use Australian dollars

Without any audio source or speakers on output attached, the Crown CH1 Amplifier (as soon as you put the on/off switch to the ON position, the CLIP light blinks a couple times and the FAULT lights blink...

It's very likely that the main power amp section has a faulty part on it that is presumably causing an overload. You should check the devices on the main heat sink of the amp section.

CROWN CE1000- slips into fault immediately after connection

if ur output power amp is defective u will have that problem - meaning the moment u connect load across it it will go into circuit protection to limit/stop excessive output current. make sure the speaker terminals are connected to +/- output terminals. in bridge mode use only channel 1 and that too with 4 ohms speaker only otherwise amp will clip. considering all connections are okay if it still clips when speaker is connected, u have a faulty power amp section. this the way ur amp is designed

The power led light just blink they don't stay on

The amp is in "protect" mode. This means that a problem was detected internally and the output section is shutdown to prevent further damage. There are many possible causes of this. Crown amps are not the easiest to diagnose as many use mulitple voltage levels for different amplification stages. I would suggest that you obtain a repair estimate from an authorized Crown service center before proceeding.

Please keep us posted on your progres.

The fault light immediately comes on my Crown XLS 602 power amp immediately upon turning it on. It will not go out?

Hi try disconnecting the speaker outs and turn off bridge (if its on) If it doesnt work still, then suggest direct to a crown agent. The amp has a 3 year no fault warranty. Hopefully its still in!

All the best

Will not go past fault red lights flash

Ths unit is in portect mode and requires service. These are not the easiest to work on as they contain multiple levels of amplification that kick in at different times. Search for an authorized service center for Crown amps. If you can not find one, please update this with your location and I'll try to locate a service center for you.

Is it clipping for real or overheating ? It may just be a fault with the indicator light circuitry itself. Make sure the input levels of the amp are matched with the output levels of whatever device is running into the amp, they will either be +4 dbm or -10 dbu, if you have a choice you want them to be set at +4 dbm. Crowns are professional amplifiers and withstand years of hard touring on the road, it would definitely be worth it to take it to a good repair shop if you can't remedy the problem yourself.

Electrical prob

This in an indication that there is a problem detected in the final output stage of the amp. This amp will require service. Crown amps are not teh most straightforward designs and should not be repaired by an inexperienced tech. There are high voltages present inside these amps that can be dangerous. The typical cause of this symptom are bad output transistors. Expect a parts cost in the $40 range plus the local labor rate.

Crown ce 4000 amp wont work

Crown CE amps have a very decent service manual that give test points to check for faults. In these amps protect mode is a good sign that major components are not burnt out ie, (Transformer).
With a good Digital volt/ohm meter most common circuits can be checked against the service manual specifications. Usually in these amps the Zener Diode or Capacitors are the first to burn out along with cooling fans. That would be a good place to start.
