Mac,
And you hit it directly on the head when you said "backs up their work with a warranty period that covers any work done." If the unit has separate power amps for each channel, they may work on the right channel, but leaves the left channel alone. That would not be covered under the warranty.

Now, as a technician, I do stand behind my work, and you can bet that if I was on that bench, I would be looking at both channels to make sure that there wasn't damage from a power spike or some other 'insult' to the circuitry that took out the one channel, and may have left the other marginal.

However, many companies, including ours, say 'we warrant the work we did.' If the other channel dies, even though we checked it, tested it, burned it in for 48 hours or more and cleared it as okay and sent it back to you, that other channel is on you. This is just the nature of the business right now. Companies can't afford to warrant parts of a unit they didn't work on. It's the economy. It may not be fair, but that's what's happening, and I'm hearing it from a lot of customers.

Danny, I recommend that you get a very detailed warranty explanation about what will and won't be covered and for how long after the company repairs it, and make sure you get it in writing.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
