Thanks for the confirmation regarding the PRIME's power supply, Nick.
I tested the CONNECT with the PRIME power supply. It seemed to have no issues with the power, but could not detect any channels either. The behavior is inconsistent (with both CONNECT and PRIME power supplies), in the sense that sometimes it detects around 3 channels (which can be watched as well), but on other scans it detects 0 channels. This does seem to eliminate the power supply as a root cause I think. Thoughts?
I also tested the coax line and the antenna, with a TV sitting right next to the CONNECT. The TV got 79 crystal-clear TV channels, a couple of additional channels with poor reception, and even a few audio channels (from our local PBS affiliate). So, I think the coax, antenna and reception quality can also be eliminated as root causes.
Finally, I noticed something else today, which makes me think it is something inside the unit which is failing - the amplifier, ROM, or some other component. Here is the behavior, which I was able to replicate at least twice:
- Scan channels on the CONNECT, until at least 1 (or more) are found - I have been able to find a max of 8, though 3 is the most common number. It takes a LOT of tries though.
- Watch at least one channel to ensure it works, and save the stream address/url
- Wait for some time (I have tried from 15 minutes to a couple of hours)
- Scan again - this time 0 channels are found, and the lineup.html page also shows 0 channels, no matter how many times you refresh it
- Try to watch the channel from Step 2 above (using the saved URL) - It doesn't work
- Power off the unit, wait a few minutes, and power it back on
- Navigate directly to the lineup.html page, and voila! Some channels have magically appeared (usually 3), which can be watched as well
I don't know all the inner workings, but it seems to me that some storage/ROM/RAM component somewhere is still holding on to an old channel scan, which shows up after the power down/up. I've seen this happen in routers sometimes, e.g. when you flash a new DD-WRT build, clear the settings, power down/up, and find the old settings still there. Usually this is fixed by a hard (a.k.a. 30-30-30) reset, but I'm guessing that would be too much to expect from the CONNECT?
Please let me know if you think this unit is dead/dying. (Sigh) I'll start looking for a new one.
Also, just for my curiosity, is there something I could do with this unit, except trash it? I'd love to tinker with the innards, knowing full well that it will void the warranty, nothing is guaranteed etc.
