A channel scan is a vital part of utilizing your cable TV service. When a coaxial cable is connected to a TV, sometimes it will not display any channels until you configure the TV for your specific cable connection and scan for available channels. A channel scan can be applied to basically any type of TV or TV/VCR combo, even if you are missing its remote control.
Bring up the TV's menu. Look for a button on the front panel of your TV/VCR labeled "menu" or "setup." Press it and you should see a menu appear on the screen. Part of the menu should inform you what buttons you can use to navigate through the menu. If not, try using the volume buttons or channel buttons on the front of the TV and see if pressing those allows you to navigate through the menu.
Specify channel scan settings. Once you are able to navigate through the TV's menu, look for the "channel scan" "auto-program," or "auto-tune" option. This may be inside one of the TV's sub-menus such as "setup," "channel setup," or the like. The key of this step is to specify your cable settings before running your channel scan. The "tuner mode" option needs to be set to "cable" rather than "air" or "antenna." You may have to specify what cable type to use, this will be set to "std" or "standard" for the vast majority of cable providers. If you are not certain what cable type you use at home, contact the technical support department of your cable provider.
Run a channel scan. Once the scan settings have been set properly, run the scan (usually done by pressing a "start," "scan" or "begin" button.) When the scan is complete, check to see if you are getting all of your channels. Contact your cable provider if you are not sure how many channels you are supposed to be getting.
I also can't find the remote for my Sylvania
TV/VCR/DVD combo... Model number 6719DF. I don't normally use this tv
(it's an extra spare that I plug into our generator when
the power goes out... since our regular family TV is
quite big and set into the wall making it difficult to
track cords around, I drag this crappy Sylvania down
from our dining room to our family room) I did
happen to find an old Zenith universal remote that
does work with it in some ways (See directions
below). I can turn the TV on and off, set the channels,
language, clock.. etc through the Input select button
on the universal remote but can't set to "Game Mode"
after using connections with video/audio input cords
plugged into the front panel of the TV. So
Playstations, extra dvd players or vcr's, etc won't
Switching from the VCR to DVD and vice versa does
require manually setting the tv itself (remote doesn't
work with that) but at least I can set sub titles, fast
forward through chapters on Dvd's and control the
volume, etc without having to constantly walk over to
Programming the remote: I've noticed a lot of people
have tried using codes supplied by different universal
remote providers and couldn't find a code that
worked using their lists with this particular model...
there is a way that it can be done but it's a bit more
Many types of "universal" remotes give the option of
"scanning" the electronic device for a code if one is
not available or the one provided with lists does not
work... Every universal remote though needs certain
buttons pushed during the "scan" and they are all
different! Ha! So if you lost or misplaced the MANUAL
as well (like me!) you might need to do a search on a
manual for your particular universal remote, but I can
at least give you directions on programming a
"Zenith" Universal remote to "scan" for a Sylvania
TV/DVD/VCR combo model 6719DF:
Using the Zenith Universal Remote or any Universal Remote using it's "scan" method:
1: Shut off the TV
2. Press and hold "Code Search" on the remote until
the red LED light lights up and stays lit.
3. Press the device button for the device (In my case,
for my crappy Sylvania combo, I pressed "TV".)
The LED light will blink once.
4. Scanning: Slowly press and release the "Power"
button on the remote, waiting a few seconds between
while watching the TV to turn on. It's very important
that you pause in between because if you do it too fast
and the TV turns on before you press the power
button again... you'll have to start all over. I've
learned that lesson. It took 160 presses each time on that button to get the
correct code scanned! I had to do it over 3 times
before I stopped myself beforehand because I was
pressing it too quickly..
5. Right after the TV power turns on, press the "Mute"
button on the remote to set the code. It should work with few limitations (no "game" mode)
Used the tv remote go into tv Menu goto SETUP go down Ch. enter pick CABLE and enter again.Tv now will go into auto scanning for CABLE channels.After the auto scan done for the CABLE channels are finish.After this u will able to go to channel 60 to used the dish remote.
If you are feeding the signal from your digital converter into the TV antenna input, I would input the converters signal to the TVs video input instead. I am assuming your converter has a video output signal and left & right audio so you will need cables for your audio also. If your converter has only rf output for the TV tuner input it is generally on either channel 3 or 4 and there may be a switch to set this. It is possible that when the TV scanned for channels the converter was off and it did not find a signal on 3 or 4. If you can get the TV to re-scan, be sure the converter is turned on and on an active channel. All your channel selection should be via the converter after that and the TV simply stays on 3 or 4. I would suggest looking in to getting the original remote. Try partstore.com and see if they have one for your model.
You need to go into the service menu and turn the ac power setting to off and read to see if you can get the channel to scan To enter service menu: hold down menu on remote until menu disapperar then type in 9-8-7-6 then enter. Continue as described
I've seen a similar problem like this caused by a stuck button either on the set or the remote control. IF one button has no effect then that's the one that's bad. This might also be your problem.
If not then something has failed in the system control circuit.
