Cannot have a full screen

Try using the wide mode. There are multiple screens you can get such as wide, zoom, full, and wide zoom. Go through these til you get the picture you want.

Comcast remotes generally do not allow you to use the menu option for your TV. Check the Dynex website by entering your model number to find the manual for your tv.

I think the backlight is failing, you will need to have it replaced. It is also possible that the backlight inverter (power supply) may be faulty but that usually shows up a fault. I think it unlikely that the screen itself has failed unless it has been subjected to pressure damage.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

Hi Mic,

Can't get full picture ?
If this is for running a dvd if it is not a
full screen version of the dvd then you
will not get it.
If it is widescreen addition you will get the
black bars at the top and bottom.

If you can't get full screen in normal mode a
few things could cause this.
One if your running from your "say" direct tv box.
You will need to try your Format button...second
button on the left of the remote.
Second you could try the restore settings on your
tv, it will restore the settings to the manufacturer's
original settings.
Keep in mind that not all tv channels are full screen.
Example: If I watch nfl gameday in HD it is full screen.
If I select the same program but, not in HD the screen
is smaller. thing it goes to a 4:3 aspect ration..
Switch back to HD and it's full screen again.

hope this helps some.

1. use the zoom/strech feature in your menu or on your remote.

The issue here is LOW def and it comes in at a smaller resolution witch is normal.

you just need to use the streatch/zoom feature,


Thanks

Press Zoom Button or Screen Size in your Remote Select Full Size for permanent Full Screen.

Check if you have the full power voltage in your home. You should have a full screen if voltage is
full 110volts.

check you remote ,,,

i want full screen on my tv

in order to get the full HD experience you should be using HDMI cables. if you're using the white/red/yellow cables then your HD channels will not broadcast in full HD and you'll be stuck with the annoying black things around your screen
