Home Entertainment issues

[CMorg]

I just bought a 58" Plazma Samsung series 5 tv and a Samsung sound bar , wireless subwoofer system. The tv has a great picture , but the issue is that it occasionally experiences a problem. The problem is upon power up it sometimes goes threw a flashing , on off on off type routine , like its trying to shut its self off to fix this just turn off the dish reciever then power back up. But my more annoying problem is the sound bar will just turn itself off , or volume down by itself ? WTF ? It is really annoying. The place I bought it from , the owner came out , and luckily seen it all for himself. He replaced the fiber optic cable for the soundbar thinking maybe it was bad , but it still does it. He moved the power wire to another outlet on the surge protector and then the tv power light just flashed and wouldnt even turn on ? Any suggestions ? Ps , my LG LCD I replaced never had any issues , and all the other equipment was the same , same dish reciever and cables/power strip..also the owner said he would replace both items. He even ordered a new tv today and it should be in tuesday. I am still curious though..
