Most shops charge a fixed fee for labor and add in the parts cost. The capacitor cost can be anywhere from $1 each to over $10 each, depending upon their value and voltage rating. Typically I would charge between $80 and $120 for labor with a unit like this. Since this is a part time job for me because I like the work, my charges tend to be less than a full time shop.Realistically, this type of repair would cost between $150 and $200 and should include both a warranty for the work as well as bench burn-in time.

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.
GK 1001 rb speaker overload, is my guess
This problem is not likely to be a volume control problem. There is a transistor inside that is failing (getting noisy) when heated up. If you have no experience with amp repairs, do not attempt this as it is not simple to locate the defective part. Continued use in this condition can cause problems with the speakers. Please have this serviced by a repair shop with experience with GK gear.

Left channel erratic
You may luck out by using a spray can of electronics contact cleaner and spray the controls through the front end. If you can take the knobs off, that would be good.
You can purchase the contact cleaner in an electronics store such as Radio Shack.
I have a Crown CE1000 power amplifier. I turned it
Unfortunately Crown amps are not the easiest to repair as they utilize multiple levels of amplification. Since you saw a flash, a resistor probable smoked, I would recommend that you bring this to an authorized service center.

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.

Fault lights
I'm not sure what you mean when you say the channel 2 does not work in bridge mode. Bridge mode effectively turns the amp into a mono amp, thus there is no channel 1 or 2. The fans will only turn on when the heat is high enough, so that is not a problem. Please describe what you perceive as the problem with these and I'll try to help.
Thanks,

You have bad connections at the inputs. If you can solder, carefuilly remove the board that has the input connector and resolder the jack onto the PC board. This should be done ASAP as with the connection loose like that the circuit board traces are soon to break.

CE 1000 ... Inverting or Non-inverting???
Hi oldschoolrid
The inverting and non inverting is to phase the speakers correctly, particularly for low frequency reproduction. . If say you had the amp driving subs at the back of the room facing say for the example full range speakers at the front of the room, then you would need to invert the signal to prevent phase cancellation occurring. If everything is facing the same way, you need to use the noninverting setup for the bass towers.
am more than happy to answer

Hi waveybnc
The fan has failed, or is
clagged up with dust. Remove it and clean it first. But best to just replace it. They are not that special and there is not
alot that stops them from working. You can get a replacement device for the amp from
Crown direct, or once you know its dimensions and power requirements, from
here.Thanks for using
FixYa. Please rate my advice to you here as
FixYa if it helps you.

Feel free to request specifics if needed.

Look first at the output transistors. Those are the most likelt defective parts. Due to the odd design of the output section, Crown amps are difficult to repair. If you get lucky, only the outputs are smoked. Also, make sure that you change all of hte transistors for the channel that has a bad one.

Clip led
That particular channel is blown. These are not the easiest units to repair. Given that this is a commercial amp, I would recommend that this unit be brought to an authorized Crown service center for repair. Expect parts cost in the $50 range plus the labor charge.

Sensetivity switch and bridging
sensitivity switch select best position of the input level to get full power when you set level control at maximum. in your situation 26db position is better.

Hi monmax,
I hope you are aware that in bridged mode your amp will become monaural (single channel, double power). If you still wish to bridge it:
Switch of power.
Set mode switch behind amp to "bridge" position.
Connect speaker positive to CH1+ve terminal of amp output and connect speaker negative to CH2 +ve terminal.
Be aware that now, in bridged mode your amps output power delivery is 1100 watts for a 4 ohm speaker and 900 watts for an 8 ohm speaker. Make sure your speaker can handle that.
Peace
Jango.
