1answer

I have a Crown xti 4000 amp that does not power up. Nothing appears burned or damaged and I already replaced the 470mF and 220mF electrolytic caps that apparently are the usual cause.

This uses a switch mode power supply that will not be happy on a variac!
Is the power supply running correctly is the first thing to check.
470mF is a very large value = 1/2 Farad! Did you mean 470nF perhaps.
Follow the service data for voltages and test points.

My amp was blinking while it was working then it went off.Now it doesn't power up..Crown Xti 4000

Power supply likely failed. Electrolytics are the primary culprit.
It should have a switchmode power supply, so it is lmost likely the 5 volt section failed.

Crown Xti 2000, signal to both channels, no sound out of one, swapped speakers, connectors, etc. , still no sound out of one channel

common problem with xti series... all the amp needs is a soft ware update contact crown and they can sort it for you... you dont have to send the amp back to them. it was a verry common fault with all the early xti amps..

Hiya, to unlock press PREV and NEXT until it says unlocked.

The short 1 sounds a little serious though. Have you tried taking off the speakers?? If still there then suggest contacting crown. They have a pretty good no nonsense 3 year warranty

Best of luck
