Alright, so i buy this home theater system. i hook it up to my tv, and my tv has my xbox, dvd player, and vcr plugged into it. It works fine for a little bit, then it just seems to die, no matter what im doing, i could just be listening to music and it would just shut off. not even the little stand by light would be on. Its really really wierd. I have a phillips mx 3550 dvd/reciever,xbox, sylvania el cheapo vcr, sanyo dvd that i bought about 2 years ago, and my xbox all plugged into 1 $30 Wal-mart power bar. oh and the woofer for the reciever. I tried using different inputs/outputs. i tried my other speakers, i tried disabling the surround and making it just stereo(FL,FR,Sub), but after about 30 minutes of useage, it dies.then i have to wait a bit to turn it back on, then it cuts out in an even shorter length of time. im thinking it has something to do with the cooling. like it has a circut or something that cuts it if it "overheats". any help appriciated and thx in advance.
