I've had my Sony STR-DA555ES receiver now for about two years and the other day it died on me. I was listening to music for about 2 hours at a pretty loud level and then turned it off and went to bed. Two days later I went to turn it on and it powered up but the display would not light and there was no sound. I tried unplugging everything and letting it sit for a couple of hours as recommended on the Sony troubleshooting website but it did not help. Anybody else ever have this problem? Any ideas what might have broke and how much it would be to fix it? I only used it maybe 2 - 3 times a week the whole time I had it. Thanks.
