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.

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.

When powered up the fault led light keeps blinking and amp won't come on


Without the make and model, I cannot provide any details. It would appear that your unit is in what is called "protect" mode. See the link below for an explanation. Feel free to update this with the make and model along with any further questions you may have.

Thanks,
Dan

The fault lights are blinking. No audio


If the amp is going into protect without audio passing it could very well be an internal short. In this case audio typically won't pass at line level. Have you tried turning the input gain stage knobs all the way down as well as the source material and slowly creep the volumes up? If it takes some audio before it faults you may want to double check the load you are placing on the amp's outputs. I'm assuming at this point it doesn't matter what speakers you are hooking it up too, it still crashed on you. Remember that Audio can be measured in voltage as well so you can measure the outputs of the amp with a volt-ohm meter.

Channel 2 Distorted/Clip light comes on


It sounds like the final amplification section is OK now. I'd be looking for a noisy transistor or transistor pair at the "front end" of the unit. There may also be a shorted coupling cap between the stages. If you can Email me the schematics, I can provide more details.

Gemsound power amplifier exa3955 keeps shutting off.


it is most likely that the shutting off is an precautionary system response to protect your amp and drivers. check all connections again for wrong polarity.

I have a crown ce4000 amp. it turns on,but both the fault lights & clip lights are on.i was wondering what could be the problem & what is an estimted cost to repair this amp.


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

CROWN CE 1000


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.

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.
