My digital tv is saying no singal whats the problem and how do I fix it? we have a huge antenna on our roof

If it is just one TV that is showing the NO SIGNAL…
-Be sure your TV is on the correct source or input as your CABLE or SAT BOX.
-Press the TV button on TV remote control to turn your TV ON.
-Press the INPUT button on your TV remote control.
-Cycle through all the inputs on your TV.
-Do this until you are on the INPUT your CABLE or SAT BOX is plugged into.
-You should then see the CABLE or SAT programming show on your TV.
HINT: Your TV will most likely list the TV INPUTS as: HDMI 1, HDMI 2, HDMI 3, VGA, Component 1, Component 2, and so on.
If you still see NO SIGNAL on your TV screen, see the next step below…

2 – If you have your TV on the correct INPUT or SOURCE and you still see NO SIGNAL…
-Remove or unplug the power cable from the Cable TV or SAT set top box.
-Keep it unplugged for 2 to 3 minutes.

-Keep the cable unplugged for 2 to 3 minutes.
-Plug the HDMI cable or other cables back in.
-Give it some time for the Cable or SAT box to get the signal and initialize.
HINT: Make sure all the cables that are connected to your Cable or SAT box and your TV are tight, undamaged, and secured.

My 86yr old mother-in-law has a Vizio 320VL and the coax attachment just fell out - TV only 18 months old. TV has just sat there, not pulled or tugged on. Is there anything else t do besides buy a new...

It is repairable but at least consider there is a faster solution--if you have cable or sat for signal the set has rear connections other than the coax fitting that a cable or sat box will hook up to....there are ways to get around the cable fitting that is broken.

let me know if you have questions

HDTV Converter hookup with sat. and antenna

Hi there Phil...... this switch from analog to digital has lots of folks scratching their heads. Fortunately I have some great news for you. The signal coming from the Dish network does not need a converter as it is already digital.

No video output from Magnavox VCR (MDV560VR)

You need to tune a chanel on your tv to the vcr signal, using an RF cable (aerial cable between vcr and tv). That is if your tv has an analogue tuner.

Basic TS - Turn tv off and unplug from wall outlet for 30 seconds. Make sure cable or sat box mute is off. Turn back on. If still no sound, just make sure that a dvd player, vcr or anything else connected to TV has no sound. Check antenna as well as cable or sat channels. If nothing has sound, call a serviceman to check out.

In general, you want to run red, yellow, white (composite or a/v) cables from the out of your sat box to the in of the Magnavox. Then run a 2nd set of r,y,w cables from the out of the Magnavox to the in of the TV (there may be one or several places to plug it into TV). If your sat box is an HD sat box, you probably won't get it to work with this Magnavox. This unit was jointly manufactured with Funai corp, so you will have to call 1-800-605-8610 for tech support.
