Odd, I can only offer some things you did not mention, do you have one of them TV's with the back light i.e. Aquos? If yes, disable the backlight, see if it still does it.
No, I don't have any backlighting. In fact, the room in nearly pitch-black; it is a basement room, and that late at night I turn off all other lights
Are you using the remote in IR or RF mode?
I am not sure. I understand what the terminology means, but I didn't know I had an option. Can someone tell me what the advantages/disadvantages of each are? And how do I set my remote or HR-20 to choose?
Have you ever tried to notice if the channels you're flipping through include a certain common channel each time? i.e. when you flip by a local channel the HR20 freezes, perhaps you are a creature of habit and 'flip' through the channels in the same order at about the same time?
Hmm, this is an interesting question; and the answer is a very strong "maybe". Most of the shows I watch in "real time" are the locals, which are on between 8-10pm. After that, I usually channel surf; and IIRC, the problem happens when I get slightly higher into the D* HD channels (or just past them). So there might be some connection there. I will have to start keeping notes on that one.
It is possible that a local station is sending something the HR20 does not like (psip data maybe). How about if you limit your flipping at that time frame to none, or to nationals only, does it still freeze up?
Not sure, I will keep track of this too
Have you tried to plug the HR20 into a different electrical outlet (one on a different circuit) to see if it still happens? The thinking, is that there could be something on that circuit where the HR20 is (or something which uses the same [bad] ground that the dish is using, i.e. A/C or something heavy) which 'flips' on at that time surging i.e. bad ground issue) and making the HR20 unhappy. If you suspect a bad dish ground, and you feel comfortable with doing it (careful, there could be a high voltage if there is a bad ground (hot ground), recommend using a multimeter first to insure there is no high voltage), you can temp. remove the ground FOR THE DISH ONLY, and see if the issue stops, if it does, get someone to get you a proper ground for the dish.
I used one of those light up outlet testers, and the outlets should be fine. I know this subject fairly well, as my house is somewhat old with many different wiring updates (I found 2 rooms with bad grounds before, which fried other AV equipment). That being said, the theater room is new construction; so who knows what problems will continue to pop up in the next month. There should be nothing heavy on the circuit that turns "on". However, it could be possible that the clothes dryer would be shutting "off" about that time. Again, another thing for me to keep notes on.
Unlikely, but, maybe there is an electrical panel near the HR20 which is releasing EMP (yes, it happens if the electrical panel was not properly installed) which peaks at 10pm due to some load? EMPs can disable electronics. (yes, I know this is almost impossible)
Hmm, another interesting one. The circuit breaker is only about 12 feet away, on the same floor. However, it is in a different room seprated by a very thick and highly insulated wall.
Is the HR20 the only unit in the home? If not, have you tried moving the HR20 to a new location and seeing if it does the same thing at the same time? as that would eliminate some of the mentioned possibilities.
I have 5 STBs in my house: 3 "basic black boxes", a SD Tivo, and the HR-20. No problems with the other units. The HR-20, was upstairs for about a month beforehand with no problems. The problem did start occuring after being moved, but not immediately (maybe after a month or so)
And of course, the most likely, just a bad unit, a new HR20 should fix it
Yep, I am guessing the unit may need to be swapped out. But I figure I might as well try to find the root cause (if there is one other than the STB), just in case the problem continues after replacement (been down that road in these types of situations before...)
Thanks for the troubleshooting advice! I will update this thread if I can come to any conclusions.
