What model of DVD player do you have? The RF cable jacks on dvd players are only for switching the RF. All players always use AV input/output or Component input/output, the later is the best.

No digital channels or menus


Yes, the main tuner is likely bad.

We have a Samsung Smart TV. We cannot get the signal and have installed a Digital Satellite Receiver. We have a Magnavox VCR and a sony DVD Player. We owuld like to attache the same to our TV and watch...


Hi there,

Depending on your Satellite receiver's output type (i.e. HDMI or Component - Red, Green, Blue) you should connect to your tv's appropriate external inputs. Example: if you choose to connect the receiver via HDMI, then you use the SOURCE button on your tv and select the correct HDMI input you have connected your device to. If connected by Component (Red, Green, Blue) then use the SOURCE button to select the correct Component input, and so on.

Note: HDMI is the best connection type - you won't be able to access your receiver from the tv's built in tuner.

As above explanation, your VCR and DVD devices should be connected to your tv in the same manner - unless it is a combo unit (VCR & DVD in one), in which case this device can be tuned into your chosen tv channel (via the tv's tuner).

Note: if you have one of the latest SMART tv's, it should already have a built-in "Hi Definition" tuner which will allow you to watch free digital tv broadcast (DVB).

Hope this helps...

Hi mfaille
I`m going to help you with your setup but first;
Which connection are you using from the sat receiver to the tv?
Coax / standard rg6 cable?
Did you try to manually add(in the menu/tuner setup/find channel/add) the channel you need ?

Goodmans GML22W29H work irractically come on sometime not at times


This is a problem across the range, very slow start up times and erratic operations. An impercfect fix for the tuner being slow to start up is the connection via scart or hdmi of an external freeview tuner.
I have the same issues and had to resort to an external tuner it cured 99% of my issues

Not able to scan for digital OTA channels on a JVC LT-32X667 LCD


Seeing as it does not have a digital tuner in it, I would think this would be the problem, you will have to get a box for it.

Blank screen with other displays still working


1. By View your DVR, Do you mean you can actually see a picture?
2. By "Switch Channels", are these channels being tuned by the TV Tuner?

Your LCD Panel is OK Since you have a Picture (input display in right corner)
If you can see a picture with your DVR, VCR, DVD or any external source then your TVs Video Processing is OK....if not you will probably need to replace the responsible PWB for this function
If you can see a picture with the external sources and only the TV's Tuner is not showing Video, The PWB responsible for Tuning within the TV should be replaced.

Also, if all problems are associated with only the DVR (I assume this is Sat or Cable), then it is most likely that this device is not functioning properly. Possibly lost signal or deauthorized.
