Again, last night local NBC station KXAS 5.1 had signal issues with drop out's, it caused my set to reset twice during the Olympics and lockup once. So, when I went to bed I left it on KXAS NBC 5.1, and I be damned if the set didn't turn itself on not 20 min after I got in bed, I got up changed channels to WFAA ABC 8.1 turned off the set and had NO self turn on's the rest of the night.
I watch American Idol last night on FOX 4.1 with NO issues. When I went back to KXAS NBC 5.1, drop signal and the set rebooted itself.
So to recap this past week:
1) Tv does not lockup on any other digital station (FOX, CBS, ABC, PBS).
2) TV only turns itself on when left on KXAS NBC 5.1 after being turned off for the night. (TV stayed off when left on local ABC, FOX, CBS and PBS stations)
3) Local KXAS NBC 5.1 is the only station that causes the (202 error No Signal Received) Both Channel and Signal strenght meters read in the mid to upper 80's
I have tested a different station each night this week for all the issues listed above, I don't think this is a "virus" in the digital signal. ( I watch NO analog of any kind on this set, and have nothing hooked to the analog cable input. I have NO Cable or Dish service of any kind. Attenna I use is a large channel master located in the attic thats 2 years old, and have new coaxe cable running from it.
This is not a power supply issue, as the circuit from the PS to the PBC board is broken when the set is turned off. (My Home Theather system is connected to a APC Smart UPS 700) so I don't have to worry about power spikes and voltage drops. ( and yes I even tested with out UPS being connected) Now if the digital tuner still retains a power circuit even after the main circuit is cut off, then the tuner can still receive (or pull in) the signal from the attenna, and if the tunner can reset itself (reboot) when the unit is on, then it can also reboot itself with the unit off and make the TV turn on by itself.
