    I have bought 2 of these which neither one of them worked and I tested them on 3 antennas. I used the same 3 antennas on a TV with a built in digital tuner and the antenna’s worked fine and pulled in all 5 of our local digital channels however the Magnavox fails to pull any type of signal. I returned those 2 for 2 more and the same thing happened so I’m at a loss on what to do about this because I can not return them because I used the government coupon so I’m out my 2 coupons and about $27 dollars. I am going to make some calls to see what can be done about this because I shouldn’t have to go through all this trouble.

    I had a similar experience as Paul - my Magnavox TB-100MG9 did not work. I tried it on two separate televisions. The green light comes on when turned on, but that was all. It was suppose to go into autosacan but did not, the digital channels would not change, nothing happened. So, I’m taking this one back - I’m not sure if I can get a $40 credit if I do so.

    I bought this model and am fairly pleased with its performance. I find that the remote is poorly designed, with the all-important channel up/down buttons small mand hard to use. I also have the RCA DT800 box and their receiver sensitivity seems to be the same. If it wasn’t for the poor remote, I would consider the Magnavox a good converter for the money. Oddly, when I bought this at Sears, I could not use my credit card to mpay for the balance. I was told that customers using the $40 coupon would have to use cash, check, or gift card to pay the balance. Even customer unfriendly Wal-Mart let me use a credit card to pay the balance on my RCA box.

    I currently receive channels 2, 4, 6, 7, 9 from Denver. Bought the Magnavox MG9 at Sears to get analog passthru for channel 2. The display info says it can be exchanged for an identical item. The salesman said no. You buy it, you own it forever. They’d take a check only. These rules were, apparently, laid down by Magnavox. Hooked it up and it did the autoscan. Got channels 4.1, 6.1, 6.2, 100.1 (same as 6.1). I live about 20 miles from the transmitting tower containing 4, 7, & 9. 4 breaks up and I didn’t get (and couldn’t add) 7 & 9. This appears to be a complete piece of junk. No wonder Magnavox won’t allow them to be returned. They’ve built a turkey and don’t want anything to do with them. If they can move one out they can pocket the money without worrying about returns. I guess the limited warranty stated on the back of the manual is meaningless. The real question is: “Can anyone tell me why I went ahead and bought this after reading hints of these problems in various fora”? I’m out $14 and my remaining coupon expires on June 25. Will I ever buy another Maganavox product?

    I bought 2 of these recently. When I hooked up the first one, the setup went smoothly, and I started to recieve 6 out of the original 11 chanels.

    Not even 10 minutes later, the box turned off unexpectedly. When I tried turning it back on, the light would blink for 30 seconds and then turn off without showing anything but a black screen.

    I hooked up the second one, and I had the same problem only without the setup. I turn it on, the light would blink for 30 seconds, and then turn off.

    The one troublesome thing about this whole thing, besides losing my 2 coupons, is returning it. It is pretty much like a big F you, we have your money and you can’t get it back. I am definitely going to reconsider buying any product with a Magnavox lable.

    Whatever it’s worth; I bought 2 MagnavoxTB100MW9 (no MG9 available yet) at Wal Mart. They work great; I receive the local channel extra channels also. Recently, PBS, that has 4 local channels, 9.1, 9.2, 9.3, 9.4 starts cutting out about 9:30 p.m to 10:00 p.m. I’ve been in contact with a PBS guy that seems to know his stuff. He said sometimes using a splitter, which I have, weakens the signal. However, he hasn’t any idea why the “no signal” display comes on at those hours as I get great reception during the day and early evening.

    I also had the same experience as Paul. Having been through the setup three times, after the channel scan was completed, was left each time with a “No Signal” message centered on the screen.

    The only reference found in the “Owner’s Manual” was on page 16, under “Picture Still”. Hardly helpful.

    i have rca and philco
    rca has better features like a remote you can see the buttons on
    the philco has tiny channel buttons and huge menu buttons
    which makes no sense…
    both dont pull in channels all the time..get lots of pixelation and mute
    they say just move antenna…bullsh*t..does no good
    plus if have roof antenna then what?
    this system will def tank in feb ppl will be forced to buy cable!!!
    cant wait to see the uproar when all are forced to use this
    my rabbit ears get just as good a pic

    I tried a Magnavox and a Insignia brand and both were crap. I got 3PBS channels. When I used my antena only I got 7 channles. These things seem to be a complete waste of time. Mine were $60, so I had to pay $20 each. I took them back and got full refund

  13. Mary Knauss Said,

    We just ordered cable and said screw it. I did buy two of the Magnivox boxes at WalMart with the coupons because we won’t be hooking up every room with cable, only two. I am not optimistic that it will work well. The cable companies have to be jumping for joy about now…

    I’m unable to add channels with my TB100MG9. If I do an auto scan it picks up stations great but when I move my antenna to pick up other stations it allows me to add them but says there is no signal. If I do the autoscan with the antenna in that position it picks up those stations so it’s not a matter of reception. Exchanged it for a second one which does the same thing, Magnavox is no help. Anybody else having this problem?

    This is a report from Chicago area. I own two Magnavox TB-100MG9. I have two different TV’s set up within 10 ft of each other. The kitchen TV gets digital content (28 channels) 5,7,9,11,20,26,32,38,44,50,60,66 and NO CHANNEL 2 CBS. The living room TV gets all if I tweet the rabbit ears antenna for the various stations. I noticed degrading of signal during a violent rainstorm (not from power loss). When my microwave is working, it causes interference on by living room TV.

    I think the key is the type of antenna you have. I tried 4 different models of antenna (plain to boosted w/ UHS, VHS knob styles) until I got one to work reasonable well. The kitchen TV works fine with a plain antenna, (from the living room analog setup I had). I make sure I install the all rabbit ears as close to the ceiling as possible.

    By comparison, I have the cheesy Target brand 13 in. TV w/digital tuner mounted in my basement. I get 2/3’s of the channels (of course, NOT CHANNEL 2) from boosted rabbit ear antenna.

    The gold standard is my HD-ready LCD Magnavox paired with a Panasonic DVD recorder w/ digital tuner. Once I dialed in the boosted rabbit ear antenna, it gets 29 digital channels and the original 14 analog channels (poor quality compared to the digital). Yeah, I get signal drop out and pixalation, I think its some kind of interference from overhead planes, weather, etc.

    I too am waiting until 2-09 when the digital signals are supposed to get boosted once the analog signals are abandoned. The joke in Chicago is CHANNEL 2 is spending millions creating a new studio on the BLOCK 37 (another story) property downtown. The local feedback from viewers is “…fix your notoriously lousy signal to the suburbs…”

    I live about 65 miles south east of Chicago. I receive with my roof top antenna, channel’s 2,5,7,9,11 from Chicago Il. 16,22,25,28,46,57 and 69 from Southbend In.I currently have 2 Magnavox TB100MW9 converter’s. I can get using the box, digital channel 2 from Chicago and all the Southbend channel’s I had plus a few more. I tried turning my bog 160″ antenna, did no good. I emailed Chicago Channel 9 WGN. I asked if they were broadcasting digital signals, the answer is yes. To make a long story short. Turns out digital Channel 2 broadcasts VHF. Digital channel’s 5,7,9,11 are now broadcast UHF. I temporairly installed a small UHF antenna facing Chicago. I got 2 channel 5’s and 2 channel 9’s still no 7 or 11. I think with a better UHF antenna, raising it a little higher and maybe a amplifier I should be in good shape. The folk’s that are having problems receiving digitals channel’s may want to find out if their channels switched from VHF to UHF broadcasting.

    Bought (#1)Magnavox TB100MW9(s), and (#2)Digital Stream DTX9950(s). Using various shape and sizes of homemade coat hanger wire antennas 6.5 in. to biggest possible w. wire length after straightening them…hooked to co-ax 75-300 ohm boxes. Tried horizontal, vertical, sloping… (! _ /)antennas hooked directly to converter input connection. Strong signals easy, weak hard without pointing box in direction of weakestr stations. By trial and error ( and cussing a lot) got all stations in except a weak one that can’t get otherwise w. TV before. #1 Mag… poor, limited use, #2 100% better. #2 remote turns on/off, control vol, and other advantages w. only it’s remote. Go to Radio Shack and buy #2. I am checking all 92 conversion boxes available.

    My auto setup with the TB100MG also did not work until I pressed the autoscan on the TV. After the TV went through its autoscan, I pressed the setup button on the remote for the converter box and it began to work ie. you could see the setup program.

    Unit is adequate. However, no front panel On/Off or Channel UP/DOWN controls means that if the remote control is lost or damaged, you will not be watching any TV. Also there is a long delay when switching between channels. The unit displays a “searching” sign on a black screen while it finds the other channel. It will do, but other units do it better.

  22. LindyD Said,

    What they fail to tell you (the *^$(#* government) is that if you get weak reception now, the stupid box will make things much worse. I just installed the converter box and get two channels. Heck, I get better reception on five channels with my antenna. Looks like my family will be shut out come February since the way the government is nationalizing private enterprise, none of us will be able to afford a new t.v. in 2009.

    I bought an Apex DT 502 Converter box from a Best Buy store, and I got Insignia from my neighbor. When I hooked up Apex converter box to my cheap Antennae with Sony TV (15 y/o) it has picked up all of the channels, including CBS channel 2 Chicago. It has an initial installation set-up that is really easy to go through.
    Insgnia is not that efficient, tough. I hooked it up to RCA Antennae, with my 20 y/o Sonyo. Well, it took me 6 times to set up channels searching until it found 30 channels. Still , CBS channel 2 has an extremely weak signal. I get blurred video, which follows by “no signal” message.
    For all these converter boxes, you have to click using your remote control on Menu, Channel set up, point right arrow on your remote control to channel search.
    Although the quality of video is much better than an analogue signal, the quality of programs are really nightmarish. One can slip into coma-boring.

    I’m in a fringe area between dayton ohio and indianapolis, and I got around 7-9 channels without the tuner that come in good, with the tb100mg9 I get 2, and those 2 are channels I’ve never seen before.
    From what I have seen the new tv’s with built in tuners work a lot better.
    I still have 1 coupon left, I’m going to do some research befor I get the next one and s#!t can this one.

    It’s starting to look like those of us that live in rural areas will end up having to purchase costly receivers after wasting our coupons on these cheap receivers. Would have been nice to be informed before coupons were wasted. Chalk up another one to our government and the free enterprise system. Go Republicans!

    I have had nothing but trouble with the Magnavox converter. I live in a rural area that will not receive satellite Tv and I am not paying the $3500 to have cable run to my house. I have installed a new antennae and get 6 channels on analog with the converter I started to receive 2 then the box stopped working.
    I think the government does not realize how many people will lose their Tv signal after Feb. My family will be one of them, I guess we will be watching more movies. The worst thing is I lost my money because Walmart will not refund it because of the coupon.

    I purchased 2 Magnavox TB100MW9 converters and installed one of them. I live in Elgin, Il. and have an antenna installed in the attic of a two story house. The location is high above the Fox River, but I can only receive channels 2,9,20. Sometimes I get 32. Channel 9 is not worth watching. Question– Am I in a fringe area not capable of receiving certain digital signals or is my converter box at fault?

    When I hooked mine up I got no signal. It wasn’t until I tried autoscan that it started working. I lost a few channels, like Fox and CW, but I gained 3 PBS channels. That’s pretty much all I watch anyway. And the picture is great.

    First off read the installation manual. Second if you are not receiving your signal then you need to repoint your antena’s. The TB100MG9 may have an auto scan, but you need to still point the antena’s into the correct direction. I live in a valley that has mountains in a ten mile radius. Once the antenna was pointed at the antenna relays the box works just great.

    Used my cards to buy 2 Magnavox TB100MG9…Sears. I knew i was going to have signal issues with the living room tv as it was a newer one but was never able to tune in much, the 4 majors and that was about it.The older unit in the bedroom has always been able to tune in more than its fair share..Cut to the chase..TV in bedroom..Rabbit ears(broken even) i get apx 28 channels with little to no fuss. The Main tv situation has been a fun ide, but am closing in on a final fix.I purchased a set of rabit ears(HDTV ready..what a joke.)..After a few frustrating hours I went back to the other set of broke rabbits that I had and boom, was able to get almost all the same ones but with some signal issues…After a week or so, that got anoying, so I started contemplating HOW could I MAKE one?…I have used wire and such before, so…THen it hit me..YOUTUBE!!!..Sure enough. Watched a demo, made a preliminary model scaled down, and what do ya know!!!..Great clarity and only 2 channels missing,but I can add on and find them. I live in Clearwater, FL. Additional resources can be found
    If you want to see the video demos they have go to youtube and search for DTV antenna.and there will be a few interesting videos with some shocking result..I don’t think its so much the boxes, as it is the Antenna, and of course location…
