I recently dropped my amp after a gig and once I hooked it back up only one channel works. I noticed upon start up after the fault lights go out I would hear two clicks .. now I only hear one. I'm wondering if a relay went bad or if something else could be at fault. I have no fault lights on power light is light and all connections are made.

I am a musician myself (classic rock band) I too have a crown two Chanel amp , only difference is ours is a 3000. Well don!t feel bad. I had dropped mine more than once and your right, when you turn it on you hear two clicks, one for each side, those are relays that trigger the power to come on and like warm up. I dropped mine one time and both sides were not clicking at all, so I took it apart ( lid off, unplugged of course) located the relays which were pretty easy to find as they were the first switch from where the internal power plug comes in, I moved them around, got lucky, they got loose from when I dropped. Then happened again by a helper, and this time no help. Went to guitar center and they took unit and replaced them, about 40 bucks. That was a couple years ago. Point of my story, this problem seems as mine, and I believe it is going to be a loose or broken relay for that side chanel. Thanks mike, hope this helps.

More than likely you just knocked somthing loose ( i.e. cable, header, ribbon cable, etc. ) i would start by just removing the top ( it'll probolly be pretty dirty inside ) and pokeing around just making sure connections are secured. of course dont do this with it plugged in or recently plugged in to keep yourself safe from electricity. 9 chances out of 10 if you drop somthing and it stops working you can usually physically see the culprit. also ch. 1 and ch. 2 should be identicle in the way they are designed ( circuit wise that is ) you can ( if your talented with a voltmeter ) take a voltage reading from your relays on ch. 1 and compare them to ch. 2 and see which power supply you've lost and back track from there.
