A few months ago my Onkyo receivers center channel crapped out. I didn't think to much of it as it was older and had lots of use. So I picked up a Harman Kardon avr-645 for a steal off a guy that barely used it.

Now I have been using the harman kardon for about 2 and a half months with no issues what so ever. When all of a sudden tonight the center channel output is basically completely gone... ! I have swapped speakers around and pretty well tried everything.

So what are the chances I have 2 receivers both fail on the center channel like this..... ?

I'm concerned there may be something wrong with the speaker but why would it take 2 and a half months ???


Any insight would be much appreciated guys. I will probably be dropping the 645 off at a shop to have them take a look at it as this unit isnt quite a "throw away" unit like the old onkyo was.
