Thank you all for the above insight,
Roku is installed on my HD Set. I normally watch OTA on my CRT about 4 feet away with the same antenna feed (I move the feed to the HD set with the Roku when I prefer to watch OTA in HD, how I found this issue the other night). Eventually when the CRT finally goes, I'll be using the HD full time.
Indoor Antenna? Yes but no, it's a 10' + boom yagi UHF/VHF laying in the attic above, line coming into the room, a small set top amp (Gemini PH61107 12 dB Signal Amplifier) near my second TV I tap from that but to only one set at a time.
A hang on the wall antenna is pretty useless in my local, yielding only 1-3 channels & their subs.
I did one test, the I found Roku totally wipes out my lone problematic VHF channel, & severely pixelates the Remaining UHF channels, , This VHF channel was coming in this AM on the CRT , I turned on the set powering the Roku, (I have it on a "sensing" power saver tap, usually turned completely off most of the time)...& was surprised it did NOT affect the signal when the Roku was powered.
One other thing, the power cord is tied to avoid dangling cords (isn't that the idea of the stick?). Seeing the Roku's do not come with a on/off switch, it would be nice to switch the USB port.
An Easter Egg hidden within???
Here are the instructions to fix it.
Start up the Roku and get to the home screen.
Press these 10 buttons quickly: HOME-HOME-HOME-HOME-HOME-FFWD-PLAY-REWIND-PLAY-FFWD
Select “Wireless Secret Screen” from the menu choices
Select “Interference” from the menu choices
I'm not that fast on a remote, (have issues entering address entries on my mobile).
, though this prevents all interference or reduces it? & what are the drawbacks of this setting? & I can return it to default if I it creates usability issues?
I can provide a HDMI extension to see if that works, Use the supplied USB adapter at a remote location. (I imagine Roku uses your TV's IR circuit for the remote?) Any reason why is should NOT be using my TV's USB port for power? ie: added stress in the TV power supply which incidentally I recapped the PS a few years back prior to buying the Roku.
I have the 3900 (Express Roku) on my set downstairs though my antenna feed is hosed in that location, thinking of placing it on my set with the stick to see if it affects the antenna, I was kind of on the fence on getting the 3800 stick over a second 3900R
My biggest concern was/is do I have a defective Roku or is it just is what it is?
