LCD TV LA40A650A1F. TV/DTV button does not switch from dtv to atv. continued pressing of channel selection button switches TV between atv& dtv

If you have not already, try pressing the source button on the remote control and select the DTV option that you choose to use and this should then act as the default until you select an alternative.

There is a DTV/ATV button that switches between analog and digital tuners. Using the source button doesn't change it.

Press the exit button or menu button until it goes away

Hi Hugh.

Please follow these instructions to manually/automatically update the digital (DTV) channels on the Samsung LE26R73BD.

Please use the following buttons on your Samsung remote control to navigate the on-screen menus:

- "D.MENU" - Opens/closes the on-screen menu (below the numerical key "0")
- DIRECTIONAL ARROW KEYS - To navigate up/down/left right through the on-screen menus
- "ENTER/OK" - Selects/confirms a selected option (in the centre of the arrows)

Automatic Channel Scan / Update:

1. Make sure you are in digital TV mode - Press the "TV/DTV" button on the remote to switch between analogue (ATV) and digital (DTV) modes.
2. Press the "D.MENU" key
3. Highlight "Installation" (first option) and press "OK/ENTER"
4. If asked for a PIN code, enter 0 0 0 0 using the numerical keys on the remote. If you have set a different PIN code, please enter your own code here.
5. Highlight "Select County" and press "OK/ENTER"
6. Use the LEFT/RIGHT arrows to select "UK" then press "OK/ENTER"
7. Highlight "Auto Scanning" and press "ENTER/OK"
8. Highlight "Scan Mode" and use the LEFT/RIGHT arrows to set the value to "Digital"
9. Highlight "Start Frequency" and use the LEFT/RIGHT arrows to set the value to "CH 21 . . ."
10. Highlight "End Frequency" and use the LEFT/RIGHT arrows to set the value to "CH 69 . . ."
11. Highlight "Start Frequency" again and then press "OK/ENTER" to start the channel scan.

Some of the options above will already be selected so will not need to be changed. I've provided the correct settings just in case they are incorrectly set. Note: UK Freeview stations are on channels 21 to 69 inclusive.

The scan will take a few minutes to complete and the progress will be displayed. When the channel scan is complete, the menu should close automatically and the TV will return to viewing mode. If not, press either the "D.MENU" or "EXIT" button to return to watching TV.


Manual Channel Scan / Update:

1. Make sure you are in digital TV mode - Press the "TV/DTV" button on the remote to switch between analogue (ATV) and digital (DTV) modes.
2. Press the "D.MENU" key
3. Highlight "Installation" (first option) and press "OK/ENTER"
4. If asked for a PIN code, enter 0 0 0 0 using the numerical keys on the remote. If you have set a different PIN code, please enter your own code here.
5. Highlight "Select County" and press "OK/ENTER"
6. Use the LEFT/RIGHT arrows to select "UK" then press "OK/ENTER"
7. Highlight "Manual Scanning" and press "ENTER/OK"
8. Highlight "Scan Mode" and use the LEFT/RIGHT arrows to set the value to "Digital"
9. Highlight "Channel Number" and use the LEFT/RIGHT arrows to choose which channel number you wish to scan . . .

UK Freeview stations are on channels 21 to 69 inclusive. In manual tuning mode, these need to be scanned one at a time. Please note, many of these channels are "empty". UK Freeview only uses 5 of these channels (called Multiplexes or MUX) or 6 if you have HD. I am unable to tell you which 5 channels these are as they vary according to whichever transmitter or repeater station your aerial is aligned to.

10. Press "OK/ENTER" to start the channel scan.
11. Repeat steps 9 and 10 for each additonal channel you wish to scan.

Please note: Manual scanning can cause some unexpected results - particularly if your aerial has a reception from more than one transmitter/repeater. For this reason it is better to use the automatical scan unless you have a specific reason for needing to scan manually.

Hopefully this will be all you need to update the digital channels on your TV. If you have any questions or need further assistance, please let me know.

Regards,
BElectric

These are the steps to reset the DTV features and unfreeze your TV:

1. Ensure the tv is in analogue mode, not dtv and turn it off.
2. With the remote: press info, then menu, then mute, then power. These buttons need to be pressed sequentially, not all at the same time, and in quick succession. A menu will appear on the tv.
3. Navigate to the reset option and press the left arrow key on the remote (or press the enter/ok button). The tv will reset itself and turn off.
4. Turn the tv back on & it'll re tune all its channels. DTV should be working again.

I hope that helps.

Reset the TV to the factory default settings then reconnect the DTV, select correct input then perform auto scan.

If the channel icon is greyed out and you cannot tune the channels press the TV/DTV button on the remote control unit the icon is not greyed out and tuning is possible.

Updating the Channel List Automatically You can update the channel list when the broadcaster adds new Services or if you move the TV to a new location.

1. Press the MENU button to display the menu. Press the ▲ or ▼ button to select "Digital Menu", then press the ENTER button.

2. Press the ▲ or ▼ button to select "Channel", then press the ENTER button.

3. Press the ENTER button again, to select "Country".

4. Select the appropriate country by pressing the ▲ or ▼ button. Press the ENTER button to confirm your choice. Even though you have changed the country setting in this menu, the country setting for Analogue TV is not changed. (Refer to page 11 of the user guide)

5. Press the ▲ or ▼ button again, to select "Auto Store". Press the ENTER button. When it has finished, the number of scanned services will be displayed. The existing favourite channel list will not be deleted when the channel list is updated. To stop the scan before it has finished, press the ENTER button with "STOP" selected.

6. Press the EXIT button to exit. If the signal status is poor, the "No Service found! Check the aerial connection" message is displayed. Check the aerial connection and the try the procedure again.

If the channel icon is greyed out and you cannot tune the channels press the TV/DTV button on the remote control unit so that the icon is visible again and not greyed out. This will allow you to tune the TV.

Your TV probably does not have a digital tuner connected to the DTV/ANT input. Mine didn't. I had to connect the digital antenna to a digital converter box THEN go to the DTV/ANT input. Only then would it activate the DTV menu and allow me to scan for channels. If your TV worked fine with Cable TV connected to the input, it was because your signal was coming from the digital tuner in your DVR, or your cable provider was sending you an unscrambled digital signal (not likely).
I used a digital converter box I had purchased with the government $40 coupon back in 2009 but the resolution is only 480 and looks like a Monet or Renoir. Now I am shopping for a high quality tuner.
