After about an hour or so of use, the center speaker turns scratchy. All the other speakers are fine, no matter how long they are used for. I've tried multiple speakers, multiple imputs, and changed the wiring, none or which have fixed the problem.

Re: Center channel turns scratchy.
Sorry to inform you, The driver transistors or IC is going bad, or there might be a poor solder connection on the center channel Amp. If you know how to solder, you may be able to poke around at the center channel amp circuit, with a wooden or plastic tool, and maybe see where the bad connection(s) are. To get a shop to looki at this unit, may not pay, but that is all up to you, on how much you paid for the unit, and how much your willing to pay to get it fixed. Read this great article and see if it helps you to decide. http://www.techlore.com/article/10602/How-to-Determine-if-you-Should-Repair-a-Broken-Device/

Replace center channel speaker with known good one. If no longer scratchy then the voice coil of removed unit is rubbing against the magnet pole and the speaker needs to be replaced. If the replacement speaker also sounds bad, then the amp for the center channel needs repair.
Its not working correctly I have a few different types of center channels and they all have equal sound no matter how many speakers are in them. Connection in speaker box is bad or you may have a blown speaker
if it is not working then there is another serious problem , and it could be the amp IC or the volume IC but tests will need to be done to determine what is causing the failure , but it does sound like amp IC as a suspect since the rear were not even working , did the volume seem different when turning it up or down before the center quit or after the center quit?
Yes Mark, You have a problem with a componet with that center channel. If your not a tech, dont have a schematic, or dont have any training in troubleshooting solid state electronics, unhook everythuing and take it into a repair senter for an estimate, as unless you know how to chech the parts you can cause more damage to the unit as it takes one slip and boom, all gone. Good Luck
if you say you checked the wireing ,did you check the speaker. disconnect on of the other speakers and connect up the center to see if you get sound. still no sound speakers bad. Got sound try unpluging unit for a couple of hours then try it again. still no center . Time for the repair shop. Good Luck
