Greetings. Been following this thread about the same model
Terk TUNVR1 I have. Bought it 11-30-2018.
SWV- Apr 20 2017-17:32:26-V3
HWV- ABL7802-R836-A <---this I'm pretty sure is the IC tuner chip installed.
I needed a atsc tuner, not a digital to analog tuner. This industry of cheap tuners is incredibly confusing and in bred. I think only a few make all the under $50 models.
Also in the manual this is clearly stated about recording problems - USB device should be USB 3.0
USB 2.0 standard does not have the file speed and this includes most portable hard drives with the 2.0 standard. However, a 2.0 external drive may work if it's ac powered and not off the USB port. It's a possible power issue as well when recording.
But asking this question about a possible strange behavior when just using it for OTA tuning. I live in a northern area and only able to get maximum 5 sources for around 9-11 channels. The vizio had 5 sources/ 7 channels at best.
Vizio HD tv with internal tuner. Tv tuner has crapped out as far as I can tell.
I know that Vizio had great numbers of complaints about it's tuners and their answer was to remove tv tuners from most all of their tv's starting in 2017 I guess.
So, enter the Terk. My antenna setup is fine and worked well until vizio failure. All cables are new and working at the time. Totally followed manual instructions to the tee and set up the terk for hdmi output to my hdmi3 input. Could not figure out how to bypass vizio tuner at the RF, so I went with Hdmi. Which is better quality anyhow.
The Terk almost automatically takes you to the tuning process. Terk doesn't not have a user input for cable/antenna input source so I assume it just automatically senses for it. Terk will scan for Qualm, (sp) which is Cable tv frequencies and not OTA. For Qualm, one must have an active cable service and attach that cable. I don't, but I assume the Terk will sense this as well as an source without user input.
Here's the weird. Tuning started right up, found 5 sources in less than half scanned, and with final finish, I had 5 sources or networks, with 11 different channels. 3 were weaker, but the original 9 were rock solid, much better than the vizio ever was. Did nothing but watch tv for a half hour. I did not touch anything else or used any usb at all. Didn't even enter that part of the menu.
All original cabling and such intact. Then decided to switch out to a brand new ru6 video cable as I was going to run that into the basement for my planned install of another device elsewhere and a powered splitter. I had the new powered splitter already in line and the picture was perfect in the front room where this was going on. Hoping no one trips over the cables laying around during the testing. Attached new cable, Trek came up with the logo as usual, went right to the channel tuner page. Nothing was found during the new scan. I then did a system factory reset. Tried again, nothing scanned. Did this process like 5 times. Then powered it down, pulled the power and everything else and let it sit overnight. Then next day, put it all back together like it was new. After the logo, it takes you to the tuner if you haven't scanned anything yet. I did the scan and nothing came up.
Okay, I didn't move any cables other than putting my new one in while just leaving everything where it was. So, is my new cable bad? To check that I used it elsewhere in the house and it was fine. Just to make sure, I used the original cable with the great picture and put it all back together like instructed as if new. Trek came up and went right to the channel search page, which tells me nothing has been saved yet. So, fully expecting everything to come back on this scan, nothing came up.
Reset sequence done to exhaustion, no results.
So what the heck just happened? Is the trek keeping some sort of tuning memory?
It worked the very first time with the new amp splitter which I knew worked elsewhere and I need it for this set-up regardless. When the channels were there, I tested the unit by turning it off and on and everything was fine. It was quick, very nice to see channel info, etc. I was as happy as a polar bear with a coke.
Has anyone ever had any brand tuner ever stop tuning after a simple change.
I have not contacted trek or vortex whatever yet. I don't think they would help me anyways.
I would appreciate anyone's input on this type of event with a tv tuner. The vizio still gets some channels but are very poor.
Thanks for reading.
