HD DVR Receiver Blue light on, but no signal
I have an HD DVR Receiver in my bedroom. It has always functioned well. This evening, I went to turn it on and it would not come on. The blue light came on dim, but my TV was not getting a signal. So I tried resetting as well as unplugging and waiting and then re plugging. Neither worked. Now, the blue light is still dim, but on. However the blue circle is not lit and I'm still getting no signal message on my screen.
Any help would be outstanding!
