Defective Magnavox TB100MG9?

post #1 of 15
Thread Starter 
I posted this at another section before seeing that converter boxes are discussed here. Please pardon any double posting.

I have an analog TV without cable or satellite, in an apartment building with a rooftop antenna. The antenna, BTW, is not great any more, and the management won't repair it. This is in the suburbs of NYC, about 20 miles from all TV stations. A few months back I bought a converter box, Magnavox TB 100MG9, with an analog pass-through feature. I set it up, and the scanner found several 1 or 2 digital channels and the analog channels, but the reception was worse than without the box. I gave up in disgust after a few days, and detached it.

Today I tried again. Using the regular TV controls (last 2 remotes died,) the signal is much improved over that without the box. (huh?) But when I put it on Channel 3, which the box requires for conversion, the setup button does nothing. I think I need to get back into the initial setup menu, and the directions say nothing about accessing it again once the box is already set up.

I build my own computers, so I'm far from technologically challenged. I don't know if the problem in in the box or the remote (I tested the batteries) or maybe the TV. Is the box defective, or am I doing something wrong?

Also, as I said, the antenna is not great any more. I think I'm the only tenant still using it. Would I get better reception with a digital TV, which I can't really afford, or would I be wasting even more money?

I have to revise my post. I pushed the SETUP button in hard with a pen and regained the menu. I scanned for stations, tuned each one, and they all show as having zero reception.

I switched the TV off channel 3, and now the better reception I had through the box is lost too. So am I. Sigh.

I don't think buying a new Dtv will solve your reception problems, my great uncle has a Magnavox unit and its a decent receiver.

Sounds like the antenna is your problem. If you don't want to spend a lot, you can make your own (indoor) like the "you tube antenna"

If your Tv has audio/video inputs, I wouldn't even bother trying to connect the converter box to it via the coax, unless it has only one set of a/v inputs and you have something like a dvd player connected to them.

I have a Zenith DTT901 on a Mitsubishi consol TV which is working GREAT
Since I also have a VCR, I hooked the rabbit ears antenae to an amplified splitter (Shopko $19.99 = 1 antenae lead & 4 output jacks) with 1 coaxial cable going to the Zenith and then to TV using the A/V cables which means the TV must be tuned to "input" inorder to view using the Zenith.
Another coaxial cable from the splitter goes to a Zinwell 950A (0838 ) which is connected to a 1991 Magnavox VCR (model VR3330) with coaxial cable. (The unused jacks on the splitter are terminated with resistors.) The VCR is then connected to the TV with RF cables. The Zinwell picked up all the same programs as the Zenith BUT it won't "talk" to the VCR for programmed recording. The VCR will do programmed recording when the Zinwell is off and the Zenith is on or off so I know that the antenae signal is getting through. Both Zinwell & VCR are on Ch 3.
With the Zinwell programmed to come on at the same time as the VCR is programmed, the recording is too snowy or scrambled to watch. The VCR also will not recognize all the channels that the Zinwell does and won't turn on through the Zinwell.
I know the connection sequence is correct so what am I missing in the set-up or programming? I tried re-programming the VCR through the Zinwell but only got scrambled signals.
Also, if I use RF cables and CH3 for the Zenith, would I be able to run the Zenith, Zinwell, & VCR without changing the tuning on the original TV remote????--Then I wouldn't have to keep the TV remote handy inorder to change between Ch3 and 'input'. Or will this compromise the reception quality too much. The Zenith is the main "translator" because of its Universal control. The VCR is used when I want to record a different program than I am watching: hence the Zinwell with the event (program) timer. IDEAS???

Popeetheus--
I have 2 sets of yellow-white AV jacks, one in rear, one in front. I have a combo DVD-VHS player, but I don't record, only play. The converter box is attached with an RF cable that came with the box, not a coax, but I don't I don't know if it's different.

Also, for about 2 years, I've had an outdoor antenna, Radio Shack Amplified Omnidirectional Model # 15-1634, which I've been hooking up indoors, just for my MOST IMPORTANT PBS channel 13. On advice of antennaweb dot org.

Today I received 3 channels clearly from the box, but instead of sound, I had loud static. PBS (channel 13) which I know is digital already, doesn't come in. ) Would you say the variation in what I'm receiving is caused by a defective box?. Yesterday nothing, today 3 stations. I think I don't understand the analog pass-through feature.

Could you give me more specific instructions on how to redo the wires, before I decide if the box is bad? In summary I have:

Samsung TV TXM 1967with 2 sets yellow-white AV jacks
Combo DVD-VHS that I play, but not record with
Magnavox Converter box (also says Funai) with analog pass-through (Huh?)
Extra antenna for channel 13.

Techigranny62 doesn't need to start a new thread either; there already is one for the Zinwell ZAT-950A.

So-o-o-o sorry, foxycat!! Retrack your claws. I didn't know that toes were so sensitive (and territorial), especially to new members who don't quite have the handle on navigating this forum.
Thanks for your help, dattier.

Leave everything connected the way you have it. You will need the TV remote to change between Ch3 and 'input'. To record a digital channel on the VCR leave the VCR on channel 3 and program the Zinwell to the channel you need to record. Since the Zinwell is tuning the channel the VCR must remain on channel 3 or you will get snow. To record an analog channel you can turn off the Zinwell and just program the VCR the way you have for years. Hope this helps.

Thanks. That is what I did and everything works great now.

You may already be doing this but if not you can set the VCR to record at a certain time if you are not home. Just set the VCR to record channel 3 when using the Zinwell for tuning digital channels. Of course the Zinwell has to be set or programmed to the correct channel.

I resolved my Magnavox problem. The box and remote were both defective. Too late to return them; I chucked them and bought a Digital Stream. The sound and pic are crystal clear, and the reception is consistent. Thanks for your help, people.

I have one of these boxes and it really sucks. The tuner is weak, and if you lose the remote you are basically screwed because there are no buttons on it.

Foxycat - the Magnavox TB100MG9 requires a digital antennae this is probably why it's not working for you. It might be possible for you to do this yourself and bypass the funky old apartment building antennae. I don't know New York well but I imagine it's difficult to get reception without a rooftop antennae. good luck KML

Foxycat - woops I missed your last posting. Congrats. Can you share what system you purchased that worked for you? (also I've heard complaints from others about the Magnavox system you had before but you're the first I've found who had a defective one so ... this is good to know - thanks). KML
