Are there any boxes that don't require 'autoscan' for setup?
Looking for a converter that doesn't require a scan or rescan to receive channels.
Have amplified rooftop antennas that I turn to receive multiple stations in opposite directions; the magnavox TB100MW9 requires a rescan whenever the antenna is turned. Current channels in memory are erased and then replaced with new ones---- which has turned out to be completely hit-and miss...mostly miss.
The magnavox won't allow any other channels to be added after it autoscans(channels CAN be added to the list but no reception is possible on these channels) The manual implies channels can be added manually, but apparently not so...
Have tried disconnecting antenna, running autoscan, then reconnecting antenna-----result was that ALL channels were being locked out with no reception possible even on local digital stations......

Ok This is what I found out and hopefully found your solution..
Have you heard of Double Rescan?
The Federal Communication Comission Designed a Process called double rescan.
Double Rescanning erases and thenreprograms the channels in the converter box an digital TVs memory.
To Double Rescan, you will first need to disconnect the antenna from the converter box or antenna.
Then disconnect the converter and or digital tv power supplies from the wall. Wait a minute before plugging them back in. The antenna should still be disconnected.
With the antenna disconnected run the channel scan function on the coverter box or digital tv. When the scan completes you will have completely removed any channel data the converter box or digital tv, had in its memory.
Now it's time to rescan for real.
Do this by reconnecting the antenna to the converter box or digital tv and running the channel scan function again.
Thus the double rescan is born.
If the double rescan doesn't work, then try some tips and tricks to get your converter box up and running..I will have to look up the url again that has the tips and tricks...
If the double rescan doesn't work let me know and I will look up more options..
I really hope this works..
For the auto scan to detect there must be channels present on the CABLE that is connected to the RF input- TUNER INPUT- of the TV. So check with your cable operator for the channels and you can connect. however if you are using a digital box then the channels are memorised on the box as only the output of the box is connect to the video/audiop inputs of the TV. if so select line in/video 1/2.
you should not have factory reset when you lose a chnl delete the chnl then rescan you never need to factory reset you lose the flash or newest update you had installed reflash your box and delete the chnls that are scrambled only and then rescan
My set-top box has an 'autoscan' function in the channel menu under setup. Try that to see if it will be able to find the missing channels. Here, some time after the initial changeover to digital, they changed some of the channels, and a new scan was necessary to get all again.
My set top box has setup menu, channels, autoscan to scan for channels. They changed some of the channels here after the original switch to digital, and a fresh autoscan was needed to again find the channels that moved. See if your box has autoscan for channels, and do it.
you will need to manual scan. you must put on the ariel as this gives you the pictures check the instructions. for searches, if you dont get any channels after tuning then take it back to where you got it,
Best solution would be to use an outdoor antenna with an amplifier(booster)--but in some areas you may get by with an amplified set top antenna. Just all depends on your location..
In perspective, I have an outdoor UHF dish and 10 foot VHF antennas with an amplifier and still i get only fair reception on outlying digital stations that normally come in clear on analog.
Also--this converter box must complete the autoscan with an antenna attached, or else you'll receive NOTHING; not even by manually selecting a known digital channel.
This #@!! box automatically locks out what it considers to be unused or weak channels. It makes the decisions and you're left with 'no signal' messages and nothing to do but try a rescan.....and you cannot add channels to any it has already found.
When you say you "lose" channels, you probably mean there's no signal there anymore but they are still in the channel memory. This is normal if you have a rotatable antenna. You need to mark the rotator (or just keep a chart nearby) with the heading for each channel.
If you mean you're losing channels from memory when rescanning after turning the antenna, the only solution I can offer is to record the channels found (and their signal levels) after scanning a direction. Then change directions and rescan. See what new channels have been found, what have been lost, or how signal level has changed on common channels. Then you can manually add whatever you need, and you'll know what direction is best for each. It's tedious, but you should only need to do it once.
