My 40D suddenly will not turn on

My 40D was working fine. I did not use it for several days and when I went to use it, it does nothing. No lights, not screens, nothing. Its as if its not turned on. I have checked all the switches in the battery door, replaced the 3v lithium internal battery. I've checked the switches in the card door. I've tried new batteries and new cards. Fully charged multiple batteries using multiple chargers. I've tried it with and without a lens, still it does nothing at all. No lights no displays of any kind. Its as if it just will not power on at all. Canon no longer repairs the 40D and there are no repair shops anywhere near me. The camera just suddenly went dead and does nothing..??
