Came home from work last night, turned on my amp to listen in my bedroom. No sound. I looked a little closer. Normally when the amp is off and plugged in, the power light is red, meaning its in standby. Well, it doesnt change to green when it is turned on, like it is supposed to. The amp is a Sonance sonamp 260. Never used harshly. Any ideas what the prob could be, and is it something that i could fix? Thanks
