My Denon AVR 3300 and Sony DVP-S7700 recently died a miserable death. I brought them in for repairs and the estimates to repair them were so high that I decided to just cut my losses and purchase a new Denon 3803 receiver and Panny RP91 DVD player. I suspect that one of the reasons both of these components lasted only about 2-2 1/2 years is because they overheated quite a bit in my entertainment center. I have a beautiful entertainment center that has a very cramped area for components with wood and glass doors and only a very small slit in the back for cables. It gets hot in there when those doors are closed and even when I try to leave them open it's hot. Anyone have a similar problem? Does it make sense to try to buy some type of small fan or fans to help cool things down back there? Any recommendations?
