I just tried DreamUp on another PC with same results. Also I am posting the log file from this PC.

Dream Multimedia always honored the 2 year warranty in my cases. I had no problem with Dream Multimedia in this respect.

This is the place to stay! Exactly the same problem.
This is my log file.

I have a problem with DM500HD. When I try to switch it on, the front Green LED keeps on flashing and nothing shows up on the screen.
I tried to flash the reciever but on Dreamup I am getting "upload completed, waiting for acknowledge.." and it keeps like that.
I am using ver1.3.3.12
Obviously I tried without network and without HDMI connection as per previous posts.
I then tried to log the data from Putty, maybe you can help me sort out my problem.

Looks like this fault is related to Serial Port circuit!!
