Try connecting the box using the RF cable to the TV. Put the TV on channel 3 or 4 and see if the menu comes up.

And yes, you'll need an antenna if the wall connector doesn't go to an outdoor antenna.

For those of you who are wondering, I still have my Magnavox Converter box. It still runs great. Now all I need is an Antenna that will pick up all the stations as I am on a amplified rabbit ears antenna.

Can skip auto scan...Can manually enter true RF channel number. It then brings up a small screen indicating "SCANNING." If it locates a station, it brings it up. If it doesn't find it initially, it will allow you sit on the channel and then when the channel is found it will lock it in and bring it up on the screen.

It has a signal meter, via the "DISPLAY" button or through the menu button. The one through the menu gives a full graph giving a visual, plus it gives a "NOW" signal reading plus a constant "PEAK"

reading, indicating the highest signal registered. So far, the signal strength screen does not seem to time out. AND it stays up even while changing from channel to channel.

It automatically remaps the channel from the true RF channel to its virtual channel number. The "DISPLAY" button also indicates the call letters of the station.

Has 3 Display Modes: Letterbox, Zoom and Full
Has Auto Power Down feature with 4 settings:
Off, 4 hours, 2 hours and 1 hour.
Seems to be very user friendly.

Negatives with the TB100MW9 so far: Is slower than the ATSC11 at initially locating and decoding a new station. But once it is locked, no doubt that it is better at holding and retaining the station over the RCA.

It is very small in size and very lightweight. It has an RF in and an RF out. It also has composite outputs for video, and left/right audio outputs. Initially I'd say this is a keeper, especially for the price. I would like to know if this unit DOES contain the 6th generation chip. More later. Have to head to work. Steve
In retrospect, of those of you who have used the Magnavox TB100MW9 - which apparently remains for sale in some retail stores - what is your opinion of it? Has it been reliable or do they die prematurely? Reception and performance pluses and minuses?

P.S. This would include its brandmate cousins - the Magnavox TB100MG9, the Philco TB100HH9, Sylvania, etc.

I just acquired one of these Magnavox boxes for $10 including the matching remote. I'm going to be testing it out shortly. Have those of you who have used this box over the years any opinions to offer as to its performance and how to address technical glitches that may arise?

Is an outdoor antenna feasible for you? If outdoor placement is restricted either by HOA rules (or in some condos, a simple lack of "limited common area" assigned to your unit for placement of an aerial pursuant to FCC OTARD rules), have you tried using a high-performance outdoor antenna indoors? I have had good results using a Channel Master 4221 placed indoors. YMMV.

I've had one of these since they first came out 5.5 years ago. I haven't used it continuously, so I can't report on its long-term longevity. I tend to use it as a "baseline" for testing purposes. I found the tuner very good at locking onto and keeping even weak signals, so if I'm having trouble with reception on one of my other boxes, I fire up the Magnavox, and if it's having trouble too, I know the problem is atmospheric. Or if I'm tinkering with antenna setup and the Magnavox is having trouble pulling in the weaker channels, that setup isn't going to work.

Here are my two original posts about it; they still sum up my assessment of this box:

http://www.avsforum.com/t/986114/magnavox-tb100mw9-initial-impressions/60#post_13437429

http://www.avsforum.com/t/986114/magnavox-tb100mw9-initial-impressions/60#post_13458445

My two main "complaints" - neither of them deal-breakers - continue to be:

1. Somewhat soft picture quality. Not terrible, not a deal-breaker. But I like the crisper, sharper PQ I get from the Zenith DTT-901 and Channel Master units.

2. Laborious method of changing the aspect ratio. Around here a lot of the .2 and .3 streams are still 4:3. The Zenith lets you select a permanent aspect ratio for each stream. So, for instance, I can leave 8.2 (METV) permanently on 4:3, while 8.1 (CBS) stays on anamorphic 16:9 (still comes from the box as 4:3 but then gets horizontally stretched by the TV), etc. The sometimes-reviled Dish DTVPal has a top-level button on the remote that lets you change ratio - not as good as the Zenith but still less work than drilling thru menus on the Mag. Again, something I can live with, but I probably won't pull the Mag back into service until the other units conk out.

If you read back through the posts in this thread, you'll see some discussion about the unit running kind of hot. Makes sense given that it does not use an outboard "wall wart" for power conversion and has no ventilation holes in the cabinet. You may want to consider drilling some vent holes in the top - assuming you are somewhat handy and think you can get the top off without damaging the internals. I would definitely do that to mine if I were using it on a daily basis.

Otherwise, the Magnavox is still a solid example of what the CECB was supposed to do: help people keep using their old analog TVs and not have to immediately buy a new TV when the Digital Transition occurred. Like many folks, I did that for a few years, then got a new LCD flat screen when prices came down. Now, I use my CECBs strictly to feed hard-drive based DVD recorders that lack digital tuners but can serve as "frugal man's DVRs" when paired with a CECB. The "converter boxes" still have a niche use for that, and for folks who have tough old CRT TVs, maybe in a secondary application like a garage or workshop, that just won't die.

I had forgotten about the aspect ratio feature. I stumbled across that feature on my Artecs which appear to be Zenith clones.

It's been awhile but I thought I had read that some posters were drilling vent holes in their Zenith/Insignias which also have built-in power supplies (seatacboy acquired some of those too).

I recently tested five of these old CECBs at my house using a roof-mounted Channel Master 4228. Something I learned about humble Magnavox TB-100MW - actually received a stable picture on an ultra-low-power high-VHF station that no other tuner has received at my home! On the other stations (RF being UHF), the Magnavox did not stand out in terms of reception. I guess the Magnavox CECB is "tweaked" in favor of receiving high-VHF stations.

What's really weird about the Magnavox TB-100MW was that the indicated signal strength fluctuated between 17% and 43%. On channels on RF UHF with similar low signal strength indications, there were some breakups of picture and sound. Accordingly, I suspect this unit picks up and holds onto high-VHF transmitters than to UHF transmitters.

That doesn't surprise me as I suspect the ATSC tuners are sub-sectioned into the various sub-bands in some manner, would seem too much bandwidth to do that all in one stroke. Another possibility is its tuner is better at multipath such that it's combining reflected signals nicely.

Yes, I took a 25 mile drive to the Indy area Wal-Mart that is currently stocking this unit and purchased one. My initial reaction to its performance next to the RCA ATSC11 is that I really like it. I have the UHF antenna signal coming out of a two-way splitter and feeding the two receivers. I also have a Radio Shack attenuator on the line for testing purposes. .......... I currently have them tuned to WIPB-DT-52 (49.1, 49.2), Muncie, IN (PBS) @ 40 miles. The Triax stack antenna is misaimed by approximately 45 degrees for this station and the new TB100MW9 is displaying a perfect picture with perfect audio while the ATSC11 has neither. In fact, the green LED light (indicating DTV signal)on the ATSC11 is only occasionally even lighting. Too bad there's no enhanced tropo today, as conditions are really bad at the moment............

Positives for the TB100MW9 so far: Can skip auto scan...Can manually enter true RF channel number. It then brings up a small screen indicating "SCANNING." If it locates a station, it brings it up.

This Magnavox unit was the first CECB model to show up for sale in retail stores, back in January 2008, even before the TV Converter Box $40 Coupon cards were issued. While my primary television is a modern LED HD display, we still use two SD CRTs in our home which are connected to converter boxes. I have several converter boxes, but a couple of months ago just out of curiosity decided to connect this very humble-looking Magnavox to my wife's TV. Interestingly, it performs very well indeed. This Magnavox box, and its Philco and Sylvania brandmates, are actually made by Funai. These are the most common CECBs found in thrift stores. They usually are very cheap - less than $10 - although often missing the remote. If you can find a Philips-brand universal remote which supports digital converter boxes, it should work just fine for these units.

The PQ is slightly softer than the LG/Zenith boxes, but from a tuner reception standpoint these units are fine. The signal-strength meter uses a more conservative signal measurement than those on the Zenith or Channel Master, which is to say that the "number" on the display might look lower than on a Zenith box but in reality they just use a different measurement system. On the Magnavox CECB, you will receive a viewable picture even when signal level is down around 18-20%, while with a Zenith when the signal level is shown around 50% you will experience signal break-up or loss. The tuner performance is almost identical in my own user experience, to my surprise.

The one drawback to these Magnavox/Sylvania/Philco CECBs: there is no real air ventilation. Be sure to set the unit to turn off after 4 hours, and turn it off when it's not in use. Otherwise, it will get warm to the touch. While I still think the LG/Zenith/Insignia CECBs are the best-in-breed units, these rather cheap-looking Magnavoxes actually perform just about as well and certainly working units are very commonplace and cheap on the second-hand market.

A step back in time. I take it they have an integrated power supply? (i.e. no wall wart).

Me, I'll take my CMs with superb PQ, s-video, Dolby, real EPG, and a great tuner; designed by a real RF company and built like a brick sh*thouse; a real solid remote too. Then my Zinwells as recording tuners with superb PQ, Dolby, Favorites, and a great tuner.
Of course I'll take my HD tuners I picked up cheap in the used markets over all the CECBs.

The Magnavox isn't the best CECB. It has a really cheap feel, I'm simply noting that when I recently tried one with a spare bedroom TV it worked better than I had recalled. Although I really don't use them much, I have a bunch of CECBs acquired second-hand. I actually have three Zenith DTT-900s, one Zenith DTT-901, one Insignia NS-DXA1, and several of the Zenith/LG remotes to provide backup if one is misplaced or dies. To my mind, the LG/Zenith/Insignia boxes were the best overall CECBs. I have a Channel Master CM-7000 in working condition but without the original remote; a Philips universal remote is programmed and works fairly well. It's a good CECB and using an S-video equipped TV the PQ is a bit better, but honestly I think the LG/Zenith tuner is neck-and-neck with the CM. I also have one of the Zinwells, without the factory remote; the Philips u-remote code doesn't quite replicate all of the Zinwell command functions. The Zinwell has some impressive features, particularly the signal-quality meter along with the signal-strength meter, and the PQ seems to be very good for a composite connection.

My point here is for the casual viewer who simply wants to watch TV in the garage or a spare bedroom, who finds one of these cheap-looking Magnavox CECBs for $5-$10 in the thrift store, this is a better CECB tuner than I had previously thought. The cheezy appearance, odd remote-control design, and lack of box ventilation would seem to be a recipe for "junk" but I have kept that "magnacrap" CECB connected to that old TV set and it still works darned well. Again, the Maggie CECB is not the best in breed - that honor IMHO belongs to the LG/Zenith, with strong competition from the CM (hard to find cheap on the used market, and somewhat trouble-prone) and Zinwell.

Speaking of which, now that flat-panel LED sets with built-in tuners have become overwhelmingly mainstream, we are seeing a lot more used CECBs in thrift stores. I've stopped buying them as I have ten in my house now! The only digital TV tuner I'd really like to buy used at this point would be a Samsung HTB-260F HD box to use with an older HD CRT set whose ATSC tuner died.

I should have quoted your Zenith best-in-breed sentence as that's really what I was referring to.

Consumer Reports listed the CM and Zinwell on composite in their top-tier PQ while the Zenith was mid-tier. Of course s-video boxes blew them all away.

There's some really nice satellite HD boxes, the ones right before they locked out the free ATSC feature, on the cheap out there. I'd buy those and sell off the ol' CECBs.
