Has anyone else had issues with H25-700? Reason I ask: Just received mine a couple of days ago. At first, everything was working perfect. I plugged in the coax, and the power and boom, we had picture. I was able to activate the receiver with DirecTV, in little time. Here's where the fun started. After activating I was watching the news and 15mins later the receiver just reboot itself. It did this 3 times in a row. So, I decided i'd unplug it and wait about 10mins. After waiting, now the box wont even power on. Nothing. I do see a green light in the back of the receiver (were the power code goes) but nothing else. I was told by someone, these boxes have a over heating issue? Is this true? First time in a long, long time I've had a problem. There going to send out a replacement so, will see what happens.
