Purchased the HT-s3400 last week, Set everything up with an lg 42LH50, ps3, xbox 360, and the hd cable box from verizon. Only complaint was the TREMENDOUS amount of heat that it puts off (i actually added some fans to my entertainment center for it). A few days went by everything was going smoothly. Last night, i was on my computer playing a game (tv was just on watching a tv show through the cable box which was hooked up through hdmi to the 3400) Suddenly i began to smell burning electronics, i looked back and my tv was off along with the 3400. Upon investigating more, EVERY SINGLE component was dead, the ps3, 360, hd cable box, as well as the tv. I decided to dismantle my tv, and the cable box. Both of them had components inside of them related to the HDMI ports, toasted. The s3400 hdmi port that the cable box was plugged into was burnt beyond recognition as well as the hdmi cable end that was plugged into it. Beware of this unit, i will be talking to onkyo tomorrow to see how things go with them. I would not purchase this unit again.
