Channel viewing issue, is it the box?
I own an SA 8300HD. Over the last few days the reception on some channels has become progressively worse, to the point that a few of the channels are completely black with no sound. As they were getting worse, the sound would stutter, the picture would break up with blocks here and there, etc.
This is occuring on both SD and HD chanels.
Looking at the diagnostic screen (Page 5) for the Current QAM, all channels are showing a Level of plus 15 dBmV and a S/N that varys between 29 and 31 dB.
I have also noticed that as the QAM frequency gets higher, the picture/sound quality drops off. For example, a channel with a QAM frequency of 600 Mhz or less is fine. Channels with a QAM frequency between 600 and 650 Mhz have issues, and channels higher than 650 Mhz are pretty much black with no sound. Additionally, on the channels that are black with no sound and above about 700 Mhz, the Status sometimes shows "Unlocked".
I have done the cold reboot (unplug, wait 30 sec.) with no change. I also removed one splitter immediatly up from the STB, again no change. The next splitter is for my cable modem. I have not noticed any issues with my cable internet connection.
Given the above, am I looking at a dying STB?
I will be giving my provider (Videotron) a call tomorrow, but would like to be armed with more info if that is possible.
Thanks in advance,
