I have a Pioneer Elite VSX-49TX receiver that gets quite hot when playing a movie in 5.1 or 7.1 sound. It has quite a bit of space in my equipment rack. I was watching "Lethal Weapon 4" & about 4 times through the movie the soundtrack quit playing & the speakers gave a high pitched sound. I hit stop on the DVD player & when I hit resume the movie started playing with no sound. I could see the picture however. I turned the DVD player off & back on & the 5.1 soundtrack came back on with the picture. The last time this happened the receiver shut off. I felt of the top of the receiver & it was extremely hot. Has anyone else had this experience with their receiver? This has only happened one time before to me along time ago & I can't remember if it was this receiver of the one I had before it. I may need to get fans since the receiver puts out so much heat. What type of fans would I get for my entertainment rack? Would I have to drill holes in my rack for them? Are there battery operated ones or is it best to go with electrical fans? Thanks for your replies.
